Abstract:
The low intake of fruits and vegetables is a global issue. This research aimed to determine the association of fruit and vegetable intake with waist circumference and barriers of intake. A total of 279 female students from the International Islamic University Malaysia, Kuantan, were recruited through convenience sampling and provided with a set of questionnaires to identify their fruits and vegetable intake. The waist circumference of respondents was measured. The majority of students consumed only one serving of fruit and vegetable per day, which is less than the levels recommended by the Malaysian Dietary Guideline. Only 9.0% of students had a fruits intake of two servings/day, while 6.5% had a vegetable intake of three servings/day which meets the recommendation. There was no significant association of fruits and vegetable intake with waist circumference among female students. Non-availability and not delicious were identified as major barriers to fruit and vegetable consumption respectively. In conclusion, the fruit and vegetable intake among the majority of female university students is inadequate. Thus, there is a need to increase awareness and develop strategies to promote adequate fruit and vegetable intake among this specific target group.

Abstract:
A scanning electron microscope study of citrus fruits was performed to assess the colonization process of antagonistic yeasts to green mould of Tarocco oranges under artificial inoculation. Yeast suspensions of Debaryomyces hansenii DBVPG 4025, Pichia guilliermondii NRRL Y 18134, P. anomala J121 and Saccharomyces cerevisiae P1.6 with or without addition of 1% CaCl<sub>2</sub> + 0.1% Tween 80 were evaluated. Penicillium digitatum was sprayed one hour later. Observation of fruit surface waxes revealed marked morphological diversity. Yeast cells and conidia were mostly localized on epicuticular waxes, particularly in naturally occurring small pits. The size of the wound affected the number of yeasts and conidia penetrating inside. Treatment with CaCl<sub>2</sub> did not affect the waxes and/or the behaviour of the yeasts and pathogen.

Abstract:
Tomato is an important plant grown in tropics as a perennial plant and in other areas mostly as annual plant. Tomato plant grows upto an height of 9 feet. The flowers are small, yellow and have five lobes on corolla. The fruit colour is green when unripe and red when it is fully ripe. Fruit is low in calorie and rich in vitamins and minerals. Genetic variability, heritability and genetic advance were assessed in thirty five genotypes of tomato at Departmental Research Farm of Vegetable Science, UHF, Solan, HP during kharif season, 2016. The experiment was laid out in RCBD with three replications. Analysis of variance revealed highly significant differences among genotypes for all the characters under study. The PCV (Phenotypic coefficient of variation) and GCV (Genotypic coefficient of variation) were higher for fruits per cluster (49.66 % and 49.50 %), fruits per plant (46.28 % and 46.11 %), yield per plant (38.13 % and 38.04 %) and average fruit weight (30.39 % and 30.29 %). High GCV and PCV provide the possibility of improving and fixing the characters through selection breeding. High heritability along with high estimates of genetic gain were observed for number of fruits per cluster (99.33 % and 101.63 %), number of fruits per plant (99.28 % and 94.66 %), fruit yield per plant (99.52 % and 78.18 %) and average fruit weight (99.35% and 62.19 %). High heritability and genetic gain suggest the possibility of improvement of traits by means of selection due to existence of additive gene effect. Selection for these above characters will be fruitful in improving fruit yield in tomato.

Abstract:
The production of passion fruit is important in Brazil. In order to contribute to the development of the most promising cultivars of passion fruit, this study aimed to evaluate the agronomic performance of 32 genotypes of passion fruit in Federal District of Brazil, and to estimate genetic parameters for use in breeding programs. Thirty-two genotypes were used in a randomized block design, with eight plants per plot and four replications. The experiment was conducted in field. Twenty-eight harvests were performed, and the variables analyzed were: productivity estimated, total number of fruits per hectare, average fruit weight and these characteristics following classification of fruits in five categories. The genotypes that presented the highest total yield estimated were MAR20 # 23, AR 01 and PLANTA 7. For industrial purposes, genotypes MAR 20 # 21 and BRS Gigante Amarelo were superior. For fresh consumption, the genotypes with the best performance were PLANT 7, AR 01 and MSC. Total productivity estimated and total number of fruits per hectare in the first-class classification showed high values of heritability and CVg/CVe ratio. These results indicate a favorable condition for selection.

Abstract:
The purpose of researches was the assessment of commodity and consumer qualities for fruit of promising apricot forms which have been bred in the Michurin Federal Scientific Center. 8 apricot genotypes breeding in this institution were studied. The regionalized variety U’lyanikhinsky with its high level of commercial consumer qualities of fruit was used as a control. Fruit skin strength was assessed at the stage of consumer maturity using an FT30 penetrometer with a plunger diameter of 8 mm. Weighing was carried out on an AND EJ-6100 laboratory balance. The content of soluble solids was determined with an MT-032ATS field refractometer. Statistical data processing was carried out using computer programs Microsoft Excel 2007, Statistics. The largest fruit size was marked in Cezar variety. Average and maximum weights were 42.3 and 59.1 g, respectively. The least stone-to-fruit weight ratio (6.6 %) was found in Viking variety. The sample varieties Cezar, elite forms №1 and 3-5-7 are considered to be as freestone apricots. Elite form No. was characterized by an excellent taste of fruit. The fruits of the control variety «U’lyanikhinsky» and elite forms №1, 1-1-24 were distinguished by a strong juiciness of the pulp. The extremely rich fruit texture was observed in control variety U’lyanikhinsky and in Cezar variety, elite form № 3-5-7. The fruit of varieties Cezar, Viking and elite form No. 1 had the firmest fruit peel. The aforementioned apricots combined the attractiveness of fruits, their one — dimensional ground color with bright over color. Under the circumstances of the Central chernozem region the varieties Cezar, U’lyanikhinsky, Viking and elite form No. 1 pay attention to their high commodity and consumer qualities of fruit.

Abstract:
Comparisons are reported for developing predictive models for dry matter across a wide variety of fruits with near infrared spectroscopy instrumentation, using a number of commercially available hand-held portable instruments (NIRVANA by Integrated Spectronics, F-750 by Felix Instruments, H-100C by Sunforest and SCiO by Consumer Physics) and an in-house laboratory based instrument (Benchtop). Three intrinsic (same fruit type) and combined (all fruit types) data sets were created from two separate batches of fruit populations. The first batch (Lot I) consisted of 205 ripe fruits from three different main fruit types (apples, kiwifruit and summerfruit) and 12 distinct fruit sub-categories. The second batch (Lot II) consisted of 91 ripe fruits from two different fruit types (apples and kiwifruit) and seven distinct fruit sub-categories. The laboratory based Benchtop instrument performed the best overall with typically higher prediction r2 values (>0.92). The hand-held instruments delivered moderate to high r2 values between 0.8 and 0.95. Results obtained with the intrinsic data sets revealed typically lower root mean square errors of prediction for apples and kiwifruit (0.32% to 0.73%) and larger prediction errors for summerfruit (0.53% to 0.82%). Some large performance variations between instruments of the same type were observed suggesting caution in evaluating the relative performance of different instrument types or formats on the basis of data generated with just a single instrument and/or data set. However, performance differences between the different hand-held portable instruments, on the same data sets, were often not statistically significant ( p < 0.05). Instrument choice for any particular application will likely come down to matters not considered here, such as, for example, ease and accuracy during in-field operation and overall reliability.

Abstract:
Despite dietary recommendations that have repeatedly underscored the importance of increasing consumption of fruits and vegetables, intakes worldwide are lower than recommended levels. Consequently, the diets of many individuals may be lacking in nutrients and phytonutrients typical of a diet rich in a variety of fruits and vegetables. In the present study, we estimated phytonutrient intakes by adults categorised by sex, level of fruit and vegetable consumption ( < 5v.≥ 5 servings/d), and geographic diet cluster. Intakes of nine select phytonutrients were estimated from the 2002–4 World Health Survey fruit and vegetable servings intake data (n198 637), the FAO supply utilisation accounts data, and phytonutrient concentration data obtained from the US Department of Agriculture databases and the published literature. Percentage contributions to each phytonutrient intake from fruit and vegetable sources were also estimated. Estimated intakes of phytonutrients from fruits and vegetables varied across the thirteen geographic diet clusters, reflecting regional differences in both numbers and proportions of fruit and vegetable servings consumed, and the specific types of fruits and vegetables available in the diet. The mean phytonutrient intakes by adults consuming ≥ 5 servings/d of fruits and vegetables were approximately 2- to 6-fold the mean phytonutrient intakes by adults with low fruit and vegetable consumption ( < 5 servings/d). In some cases, phytonutrient intakes by adults consuming ≥ 5 servings/d of fruits and vegetables in one geographic diet cluster were lower than the intakes by adults reporting < 5 servings/d in another cluster. The findings from this assessment provide important information regarding the major dietary patterns of phytonutrient intakes across geographic diet clusters.

Abstract:
This article investigates the possibility of obtaining genotypes of garden strawberry with enhanced fruit strength. The creation of species and varieties with the specified feature is expected to improve the quality, transportability and storability of berries. Experiments were performed in 2015–2020 at the collection and breeding plots of the Kokinsky testing station of the Federal Horticultural Research Centre for Breeding, Agrotechnology and Nursery. 29 species of the domestic and foreign selection, 7 choice species, as well as the hybrid seedlings of 22 crossing combinations and 3 open pollination populations of garden strawberries, were investigated. The aim was to identify sources of increased trength and perspective crossing combinations, affording the highest yield of seedlings with firm fruits. The examination of the fruit strength was performed at the stage of optimal maturity. Berries crushing force was determined using a VR-04MS-2-BR balance by applying pressure to the fruits until the first drop of juice appears. The measurement results were converted into international units, i.e., Newtons (1 kg = 9.8 N). The phenotypic evaluation of varieties and species of garden strawberries based on the fruit strength revealed genotypes with the firmest fruits — Kleri, Darselect, Tenira, Selekta, Polka, Tzaritza, Aquarelle, Irma and the 3-366-9 selection. These varieties yield the fruits, which endure the crashing force of over 10 N. In the hybrid progeny, the fruit strength varied within a wide range, and its significant change within the crossing combinations and populations of open pollination was revealed. The Darselect, Cleri, Irma, Tzaritza varieties are the most valuable seed parents in the transmission of the high strength character. Within the research period, the best crossing combination yielding seedlings with fi m fruits were Alfa×Darselect, Festival Romashka×Darselect, Irma×Lyubava, 3-366-9×Kleri, Nashe Podmoskovye×Irma, Festival Romashka×Kleri and open pollination population of the Kleri, Darselect, Tzariza varieties. 42.2 to 60.3 % of hybrid seedlings yielded fruits with the crushing force of over 10 N, and an average value for the families amounted to 9.6–11.2 N.

Abstract:
Cucumis melo var inodorus or known as Melon Manis Terengganu (MMT) is a new variety of rockmelon and has been developed and grown exclusively in Terengganu since 2015. However, pest infestations such as fruit flies have reduced melon production yields, and research on fruit flies is still poorly studied in this new variety. Therefore, this study was aimed to identify the fruit fly’s species infested MMT as well as to determine the infestation rate of fruit flies on MMT at different ripening stages. The infested MMT fruits were randomly collected for three consecutive weeks prior to harvest and each week was represented as unripe stage (Week 1), ripe stage (Week 2) and fully-ripe stage (Week 3). Each week, 10 fruit samples were brought to the laboratory and weighed individually before being placed in plastic containers. The fruits were reared until all larvae transformed into pupae for determination of infestation rates and emergence of adult fruit flies for species identification. A total of 232 of fruit flies adults emerged from 30 MMT fruit samples collected and all the flies were identified as Zeugodacus cucurbitae (previously known as Bactrocera cucurbitae). Unripe stage fruits recorded the highest infestation rate of fruit flies at 28.24 ± 18.58 pupae/kg and followed by ripe stage at 24.47 ± 8.17 pupae/kg. Whilst the fully-ripe stage had the lowest infestation rate of flies at 13.5 ± 5.07 pupae/kg. However, no significant difference (P>0.05) of infestation rate was recorded among the different fruit stages. This study contributes new information on the fruit fly’s species that attack MMT and its infestation rate. Hence, these findings are expected to help better management of MMT fruit flies in the future.

Abstract:
Parkid higlohosa, an important indigenous fruit tree of West Affican Sudanian woodland, was studied with respect to natural population distribution and structure, regeneration, reproductive biology and phytosociology in Nigeria. As relevant background, a comprehensive range-wide monographic account of the species was assembled. An ecological survey covering the range of Parkia in Nigeria was undertaken between 1994-1995. The survey involved four ecological zones ranging from derived to Sudan/Sahel zone transition. In each ecological zone there were two sample sites within each of which there were two land use types. The survey showed that nearest mature con-specific neighbour distance and corresponding stocking for all individuals ý: 10 cm dbh ranged from 25.5 m and 15 tree ha-I in the north down to 91.5 m and I tree ha-I in the south. A gradual increase in stocking from the lowland forest zone boundary to the Sudan savanna was observed. Parkia populations are significantly more concentrated in cultivated fields than in less intensively used areas of the bush fallow. Natural regeneration in Parkia in Nigeria was sparse overall - 9.80 individuals ha-I and coppice shoot regeneration was the main form. Bush fallow conditions favour more regeneration than intense cultivation, and to the south there is more regeneration than in the north. Tree morphological appraisal showed that there tended to be taller trees in the south of the Nigerian range (with a moister climate) but with smaller diameter than in the north. A broader crown diameter typified populations in the northern part of Nigeria range compared with the south. Branching height ranged from 1.7 m in the north to 3.9 m in the south. The tree rarely branched below Im anywhere. Two was the most frequent number of primary branches. Individuals with more than two primary branches per tree occur more frequently in the north of the range. For all morphological parameters except the number of primary branches a significant land use effect was detected. In the survey 136 associated woody species were recorded. More woody tree species were associated with Parkia biglobosa in the south than in the north of its range in Nigeria. A reproductive cycle of 135 days was observed at Saki, Nigeria. Capitulum abortion rate was more than 30% and not related to the tree diameter or crown position. Capitulum, podding efficiency was about 67%. Open pollinated capitula had the highest number of pods per treatment. Parkid displays some degree of self-compatibility. Capitula located >5 m above the ground are more likely to be pollinated than those below.

Abstract:
Durant l'última dècada, el sector agrícola ha passat de les pràctiques tradicionals a mètodes més intensius per tal d'augmentar la seva productivitat, com a resposta a la creixent demanda d'una població creixent. En conseqüència la producció d'aliments ha desencadenat una important contribució a l'esgotament dels recursos naturals i l'impacte ambiental. Per desenvolupar una gestió ambiental adequada, és essencial per a les indústries de conèixer els principals indicadors ambientals dels seus productes i processos : emissions, consum d’energia i consum d'aigua, generació de residus, eficiència, etc. Tot això pot ajudar als productors a millorar la gestió dels seus sistemes productius, donar un valor ambiental afegit al seu producte, i proporcionar més informació ambiental als consumidors. Tenint en compte que la poma i préssec són dues fruites significatives en els països mediterranis, i que la majoria de les publicacions sobre els impactes ambientals de la producció de fruita es basen en un únic any productiu, aquest estudi intenta realitzar un anàlisi ambiental de la producció de poma i préssec utilitzant amb un enfocament d'Anàlisi del Cicle de Vida (ACV), amb la finalitat de proporcionar nova informació ambiental sobre la fruita, i també introduir una anàlisi des de la perspectiva plurianual per tal d’identificar la variabilitat dels impactes ambientals relacionats amb el rendiment anual d’una plantació, les condicions geogràfiques i climàtiques. Els resultats s'expressen en termes de petjada de carboni i petjada hídrica, per tal de comparar aquests conceptes des d'un punt de vista metodològic, i també informar al sector de les fruita i dels consumidors. La petjada de carboni, quantifica les emissions CO2 equivalents relacionades amb el cicle de vida d'un producte o servei en termes d'escalfament global. La petjada hídrica mesura l'aigua que es consumeix per desenvolupar un producte d'un bé o un servei. Aquest estudi segueix un marc interdisciplinari, tenint en compte les següents etapes en el procés de producció de la fruita: fase agrícola, comercialització, distribució, el consum i disposició final, així com l’obtenció dels materials i substàncies relacionats amb la producció de fruita. Els sistemes estudiats són horts de poma i préssec situats a Catalunya. Les dades utilitzades han estat recollides directament dels horts de la Unitat d'Horticultura Ambiental de l'Institut de Recerca per a l'Agricultura i l'Alimentació i Tecnologia (IRTA), ubicat a la província de Lleida, i abarca entre 9-15 anys de producció real. Aquesta tesi contribueix a detectar els punts crítics de l'impacte ambiental relacionat amb la producció de fruita des d’una perspectiva d'anàlisi del cicle de vida, així com avaluar les metodologies existents per calcular la petjada de carboni i d’aigua, a més de desenvolupar nous aspectes metodològics, i generar noves dades sobre el tema, que seran útils pels productors de fruita i també pels altres actors involucrats en la producció de fruita. Encara que l'estudi demostra que l'ACV és una eina útil per estimar l'impacte associat a un producte o un procés, i també pel càlcul de la petjada de carboni i la petjada hídrica, encara hi ha algunes qüestions per resoldre pel que fa la qualitat de les dades i base de dades disponibles per quantificar l’impacte ambiental, ja que a vegades és necessari treballar amb dades genèriques, que poden generar variabilitat en els resultats.
Durante la última década, el sector agrícola ha pasado de las prácticas tradicionales a métodos más intensivos con el fin de aumentar su productividad, como respuesta a la creciente demanda de una población creciente. En consecuencia la producción de alimentos ha generado una importante contribución al agotamiento de los recursos naturales y el cambio climático. Para desarrollar una gestión ambiental adecuada es esencial para las industrias conocer los principales indicadores ambientales de sus productos y procesos: emisiones, consumo de energía y agua, generación de residuos, eficiencia, etc. Conocer esta información puede ayudar a los productores a mejorar la gestión de sus sistemas productivos, dar un valor ambiental añadido a sus productos, y también proporcionar más información a los consumidores. Teniendo en cuenta que la manzana y melocotón son dos frutas significativas en los países mediterráneos, y la mayoría de las publicaciones sobre los impactos ambientales de la produccion de fruta se basan en un año productivo único, este estudio pretende realizar un análisis ambiental de la producción de manzana y melocotón utilizando la metodología del Análisis de Ciclo de Vida (ACV), con el fin de proporcionar nueva información ambiental sobre la fruta, y también introducir un análisis de la perspectiva plurianual para identificar la variabilidad de los impactos ambientales relacionados con el rendimiento anual de las plantaciones, las condiciones geográficas y climáticas. Los resultados se expresarán en términos de huella de carbono y de agua, con el fin de comparar estos conceptos desde un punto de vista metodológico, y que para que la información pueda servir para informar sector de la fruta y de los consumidores. La huella de carbono cuantifica las emisiones de CO2 equivalentes relacionadas con el ciclo de vida de un producto o servicio en términos de calentamiento global. La huella hídrica cuantifica el agua que se consume para desarrollar un producto de un bien o un servicio. Este estudio sigue un marco interdisciplinario, teniendo en cuenta las siguientes etapas en el proceso de producción de la fruta: fase agrícola, distribución, consumo, residuos, así como el sistema relacionado con los materiales y sustancias relacionados con la producción de fruta. Los sistemas estudiados son huertos de manzano y melocotón situados en Cataluña. Los datos utilizados han sido recogidos directamente de un huerto de la Unidad de Horticultura Ambiental en el Instituto de Investigación para la Agricultura y la Alimentación y Tecnología (IRTA), ubicado en la provincia de Lleida en el noreste de España, el estudio abarca entre 9-15 años de producción real. Esta tesis contribuye a detectar los puntos críticos del impacto ambiental relacionados con la producción de fruta con una perspectiva de ACV, así como evaluar las ventajas y debilidades de las metodologías existentes para calcular la huella de carbono y huella de agua, además de desarrollar nuevos aspectos metodológicos y la generación de nuevos datos sobre el tema para los productores de frutas y otros actores involucrados en ciclo de producción de fruta. Aunque el estudio demuestra que el ACV es una herramienta útil para estimar el impacto asociado a un producto o proceso y para el cálculo de los indicadores huella de carbono i huella hídrica, existen todavía algunas cuestiones por resolver en cuanto a la calidad de las bases de datos de impacto ambiental y los datos disponibles, porque a veces, es necesario trabajar con datos genéricos.
During the last decade, the agricultural sector has changed from traditional practices to more intensive methods in order to increase their productivity, as a response to the growing demand of an increasing population. Consequently food production has become an important contribution to the depletion of natural resources and climate change. To develop a proper environmental management it is essential for industries to know the main environmental indicators of their products and production processes: emissions, energy and water consumption, waste generation, efficiency, etc. It also can help producers to improve their production system management, give an added environmental value to their product, and provide more information to consumers. Considering that apple and peach are two significant fruits in the Mediterranean countries, and most publications on environmental impacts of fruit productions are based on one single productive year, this study attempts to perform an environmental analysis of apple and peach production using Life Cycle Assessment (LCA) approach, in order to provide new environmental information of fruit, and also introduce a multiyear perspective analysis to identify the variability of the environmental impacts related to annual orchard yield, geographic and climatic conditions. The results will be expressed in terms of Carbon footprint (CF) and Water Footprint (WF) terms, In order to compare these concepts from a methodological point of view, and how those can be introduced to inform fruit sector and the consumers. The CF measures the emissions of CO2eq related with the life cycle of a product or services in terms of Global warming. WF measures the water consumed to develop a product a good or a service in terms of litres. This study follows an interdisciplinary framework, considering the following stages in the process of fruit production: agricultural stages, retail, consumption ad disposal, as well as the back-ground system related with materials and substances production. The systems studied are apple and peach orchards located in Catalonia. Data used have been collected directly from an orchard of the Environmental Horticulture Unit at the Institute of Agriculture and Food Research and Technology (IRTA) located in the North East of Spain, and covers between 9-15 years of real production. This dissertation contributes to detect the hot spots of the environmental impact related to fruit production with a perspective of LCA, as well as evaluate the advantages and weakness the existing methodologies to calculate the Carbon and water Footprints, besides developing methodological aspects and generating new data on the topic and fruit producers and all the actors involved in fruit production. Although the study demonstrates that LCA is a useful tool for estimating the impact associated with a product or process and calculate the CF and WF indicators, there are still some issues to be resolved regarding to the quality of environmental impact databases and data available because sometimes, it is needed to work with generic data, and it can generate variability in the results.

Abstract:
Childhood obesity in America is reaching epidemic proportions. This study explored whether daily online lunch menu information was sufficient to enable parents to advise their children about healthy and unhealthy menu choices in 350 Texas middle schools and whether online menu information strongly correlated with the descriptions of the offerings given by 52 school cafeteria managers in telephone interviews. Although schools are making efforts to describe their offerings, they are not vigorously taking advantage of the opportunity to aggressively inform or educate. They are not coding their descriptions in such a way as to explicitly brand food as healthy or unhealthy. They are also not labeling food as generally required by law for consumer services that provide food (except for the fresh produce that lines supermarket shelves). Instead, they only briefly describe what they are serving in the way of fruit in one or two word snippets. Finally, cafeteria managers’ online descriptions were inconsistent with what they described in interviews. Online and verbal descriptions were sometimes contradictory, raising questions about the accuracy of either type of description.

Abstract:
Declines in pollinators around the globe, notably the loss of honey bees (Apis mellifera L.) to Colony Collapse Disorder, coupled with a dearth of quantitative data on non-Apis bee pollinators, led to this dissertation research, which documents the role of non-Apis bees in crop pollination in southwest Virginia. Major findings of this first study of its kind in the region were that non-Apis bees provided the majority of pollination—measured by visitation—for several economically important entomophilous crops (apple, blueberry, caneberry, and cucurbits); diverse bee populations may be helping to stabilize pollination service (105 species on crop flowers); landscape factors were better predictors of non-Apis crop pollination service than farm management factors or overall bee diversity; and non-Apis bees in the genera Andrena, Bombus, and Osmia were as constant as honey bees when foraging on apple. Non-Apis, primarily native, bees made up between 68% (in caneberries) and 83% (in cucurbits) of bees observed visiting crop flowers. While 37–59 species visited crop flowers, there was low correspondence between bee communities across or within crop systems ("within crop" Jaccard similarity indices for richness ranged from 0.12–0.28). Bee community diversity on crop flowers may help stabilize pollination service if one or more species declines temporally or spatially. A few species were especially important in each crop: Andrena barbara in apple; Andrena carlini and A. vicina in blueberry; Lasioglossum leucozonium in caneberry; and Peponapis pruinosa and Bombus impatiens in cucurbits. Eight species collected were Virginia state records. In models testing effects of farm management and landscape on non-Apis crop pollination service, percent deciduous forest was positively correlated in apple, blueberry, and squash, but at different scales. For apple and blueberry, pollination service declined with an increase in utilized alternative forage but was positively related to habitat heterogeneity. For squash, percent native plants also related positively, possibly due to increased presence of bumble bees in late summer. Species collected from both bowl traps and flowers was as low as 22% and overall site bee diversity had no effect on crop pollination service, highlighting the value in pollination research of monitoring bees on flowers.

Abstract:
A fundamental requirement in agricultural trade is that imported products are safe, and do not pose a risk to human, animal and plant health. To address this issue, all countries maintain measures to ensure that imported food is safe for consumers, and to prevent the spread of disease among animals and plants. These measures, by their nature, can affect competitiveness by increasing the costs of imports or prohibiting them altogether. To ensure that these measures are used for their intended purpose and not as protectionist measures, WTO member countries signed the Agreement on the Application of Sanitary and Phytosanitary measures. A growing number of studies attempt to quantify the effects of SPS regulations on international trade flows. However, precious little research is dedicated to determining the effects of specific phytosanitary regulations on trade flows and, more importantly, questions regarding SPS regulations and their impact as "trade barriers" or "trade catalysts" remain to be settled. This thesis contributes to existing literature in two ways. First, a comprehensive and user friendly database on specific phytosanitary regulations faced by U.S. exports of onions, peas, walnuts, apples, cherries, grapes, peaches/nectarines, oranges and strawberries to 176 countries is developed for the period 1999-2009. Second, this database is used for an empirical investigation to determine how existing SPS regulations affect U.S. fruit and vegetable exports. The results indicate that initially, phytosanitary treatments act as "barriers" to trade. However, as exporters' experience grows, the negative impact of treatments is reduced and eventually eliminated.

Abstract:
To properly evaluate initiatives targeting children's fruit and vegetable (FV) consumption, we need feasible and valid dietary assessment methods that are time, cost, and resource effective. The objectives of this study were to test the feasibility and validity of two methods, digital imaging (DI) and aggregate plate waste (APW), for assessing children's FV consumption. UVM dietary assessment team graduate students prepared and distributed FV snacks in two pre-school classrooms over 30 consecutive school days. Feasibility of APW was tested by recording the frequency and weight of waste sorting errors by pre-school children and performing paired t-tests comparing uncorrected and corrected FV waste. Feasibility was tested for DI by determining the total number of individual FV snacks from which FV consumption could be estimated using the digital images. Validity was tested for DI using paired t-tests to compare FV consumption as assessed by DI against actual consumption as assessed by weighed plate waste (WPW). A total of 159 cluster APW weights were recorded during the 20 days of APW collection, with an overall mean difference of 0.57 grams (p=0.440) between uncorrected and corrected FV waste. Researchers were able to capture 100-percent usable digital images, effectively displaying 214 individual FV snack servings over the 10-day DI study period. Percent agreement between the two digital image coders was 99.1-percent. DI estimations for individual FV item and cumulative consumption were strongly correlated with WPW (all above r=0.97). Overall FV consumption as estimated by DI differed from WPW by less than one gram, and DI estimations for individual FV items differed from WPW by no more than two grams. Paired t-tests revealed no significant difference between DI estimations of clementine (p=0.954) and peapod (p=0.806) consumption and WPW measurements. However, paired t-tests indicated statistically significant differences between DI and WPW measurements for overall (p=0.001), grape (p=0.031), carrot (p=0.008), and pepper (p=0.027) consumption. Both methods were feasible for assessing mean FV consumption. DI estimations for individual FV items and cumulative consumption were strongly correlated with WPW, suggesting that despite statistical significance between DI and WPW measurements in some cases, the DI method is still precise for mean FV consumption evaluation. APW may be especially advantageous for rapid and efficient evaluation of behavior change in response to interventions targeting children's FV consumption. Due to ease of administration and instantaneous results, the APW method reduces the need for trained research staff to be present, drastically increasing accessibility to group-level dietary assessment.

This paper reports on a focused human rights impact assessment (HRIA) of Coop Sweden’s Moroccan citrus supply chains. The HRIA aimed to assess the actual and potential human rights impacts at the production stage of the value chain in Morocco, to identify their root causes, and to provide recommendations to relevant stakeholders concerning their mitigation and/or remediation. The assessment took just over a year and consisted of five phases of analysis using a methodology aligned with the UN Guiding Principles on Business and Human Rights (UNGPs). The field phase took place between January and April 2021. The HRIA was commissioned by Coop Sweden, who wanted a better picture of working conditions in the citrus sector and of the experiences of workers in seasonal production.

Full text
Abstract:
An electronic sensory system for the evaluation of headspace volatiles was developed to determine fruit ripeness and quality. Two prototype systems were designed, constructed, and later modified. The first is an improved version of our original prototype electronic sniffer using a single head sensing unit for use as a single or paired unit placed on an individual fruit surface for applications in the field, lab, or industry. The second electronic sniffer utilizes a matrix of gas sensors, each selected for differential sensitivity to a range of volatile compounds. This system is more sophisticated as it uses multiple gas sensors, but was found to enhance the ability of the sniffer to classify fruit ripeness and quality relative to a single gas sensor. This second sniffer was designed and constructed for the sampling of fresh-cut or whole packs of fruits such as packaged strawberries and blueberries, and can serve as a prototype for research or commercial applications. Results demonstrate that electronic sensing of fruit ripeness based on aromatic volatile gas emissions can be used successfully with fresh frits. Aroma sensing was successful for classifying ripeness in muskmelons, including different cultivars, apples, blueberries, strawberries, and in a complimentary BARD project on tomatoes. This system compared favorably to the physicochemical measurements traditionally employed to assess fruit maturity. This nondestructive sensory system can detect the presence of physically damaged fruits and shows excellent application for use in quality assessment. Electronic sensors of the tin oxide type were evaluated for specificity toward a wide range of volatiles associated with fruit ripeness. Sensors were identified that detected a broad range of alcohols, aldehydes, esters, hydrocarbons, and volatile sulfur compounds, as well as individual volatiles associated with fruit ripening across a wide concentration range. Sensors are not compound specific, thus, the matrix of sensors coupled with discrimination analysis provides a fingerprint to identify the presence of compounds and to assess alterations in fresh products due to alterations in volatile emissions. Engineering developments led to the development of a system to compensate for temperature and relative humidity relative to on-line aroma sensing with melons for ripeness determination and to reduce response time, thus permitting the electronic sniffer to be used for monitoring both fresh and processed food products. The sniffer provides a fast, reliable and nondestructive tool to assess fruit ripeness and quality. We hope that our work will foster the introduction and utilization of this emerging technology into the agricultural and horticultural

Full text
Abstract:
Over the last few decades, the organic agriculture sector has experienced sustained growth. Globally, as well as in the European Union and Portugal, organic production accounts for just under 10% of total Utilised Agricultural Area (UAA) (FiBL, 2019; Eurostat, 2019; DGADR, 2019; INE, 2019; GPP, 2019). This growth has been seen in terms of production, number of producers, amount of retail sales, imports and exports. This article attempts to build on the multi-level perspective (MLP) of the socio-technical (ST) transitions theory by employing a whole systems analysis (Geels, 2018) of organic agriculture in Portugal, which defends an integrated vision of the systems, where multiple interactions occur within and among the niche, the regime and the landscape levels. This approach has been employed in order to develop a critical analysis of the current state of the Portuguese organic agriculture sector, stressing the multiplicity of elements that are contributing to the agro-food system´s transformation into a more sustainable one. In fact, the agro-food system is related with climate change but also has connections with other domains such as public health, water management, land use and biodiversity. Therefore, it is affected by shifts in these areas. This analysis considers developments in increasing domestic organic production, number of producers, amount of retail sales, imports, exports, market innovations, and the sector´s reconfiguration. The organic sector´s increase has been attributed to European regulation, institutionalization, standardization, farmer certification, external (government) subsidy support programs, incremental market improvements (visibility and product access), the emergence of new retailers, the rise of supporting consumers and a shift away from conventional agriculture (Truninger, 2010; DGADR, 2019; Pe´er et al, 2019). However, together with positive incentives, this sector also faces numerous barriers that are hindering a faster transformation. Difficulties for the sector to date have included: product placement; a disconnect between production, distribution and marketing systems; high transport costs; competition from imports; European subsidies focused on extensive crops (pastures, olive groves, and arable crops), entailing a substantial growth in the area of pasture to the detriment of other crops; the fact that the products that are in demand (fresh vegetables and fruit) are being neglected by Portuguese producers; expensive certification procedures; lack of adequate support and market expertise for national producers; the hybrid configuration of the sector; and price. Organic agriculture as a niche-innovation is still not greatly contributing to overall agricultural production. The low supply of organic products, despite its ever-increasing demand, suggests that a transition to increased organic production requires a deeper and faster food system reconfiguration, where an array of distinct policies are mobilized and a diversity of actions take place at different levels (Geels, 2018; Pe´er et al, 2019). This paper will attempt to contribute an overall critical assessment of the organic sector´s features and evolution and will identify some of the main obstacles to be overcome, in order to boost the sustainability transition of the agro-food system in Portugal.
