Full textAbstract:
Summary A preliminary survey indicated that the root-knot nematode Meloidogyne javanica is widely distributed in the rhizosphere of medicinal plants in Boyer-Ahmad region (Iran). Host suitability of ten species of medicinal plants to M. javanica was examined in a pot experiment under controlled greenhouse conditions: alkakengy (Physalis alkekengi L.), chamomile (Matricaria chamomilla L.), English plantain (Plantago lanceolata L.), fennel (Foeniculum vulgare Mill.), garden anchusa (Anchusa italica Retz.), horehound (Marrubium vulgare L.), lovage (Levisticum officinale L.), sorrel (Rumex acetosella L.), thistle (Echinops adenocaulos Boiss.) and woundwort (Stachys pilifera Benth.). According to the scheme of Canto-Saenz, seven species, namely garden anchusa, fennel, horehound, alkakengy, English plantain, woundwort and sorrel can be considered susceptible hosts with gall index (GI) > 2 and reproduction factor (RF) > 1, and thistle, lovage and chamomile, can be considered as hyper-susceptible with GI > 2 and RF ≤ 1.

"A simple model to examine the impact of changes in wood traits on the costs of thermomechanical pulping and high-brightness newsprint production with radiata pine."

Full textAbstract:
A number of functions were investigated that related the costs of thermomechanical pulp (TMP) and high-brightness newsprint production, using Pinus radiata D. Don, to important pulp and paper quality (breeding objective) variables, including specific energy consumption and pulp handsheet tear and tensile strength, brightness, and opacity. Pulp handsheet quality traits were considered to be reasonable two-dimensional predictors of paper quality traits in this context. A specific production process that requires the use of a reinforcement kraft pulp and an artificial clay filler to improve the quality of paper produced from the bleached TMP fibres was investigated, similar to the production process used by Australian Newspaper Mills' Boyer Mill in Tasmania, Australia. Pulp and pulp handsheet quality variables could be explained by significant (P > 0.05) wood traits using multiple linear regression equations. This provided a method to predict the economic importance of each wood trait in relation to the thermomechanical production process investigated. The results showed that tracheid length, wood density, wood brightness, and tracheid coarseness were the best predictors of costs. Increases in tracheid length, wood density, and wood brightness and decreases in tracheid coarseness resulted in decreasing the total costs of TMP and high-brightness newsprint production.

Full textAbstract:
A geographical survey of sediments in the Derwent Estuary, near Hobart (Tasmania), for sterol biomarkers of faecal pollution has established the extent, distribution and severity of sewage pollution in the estuary. Analysis of biomarkers for terrestrial plants has also determined the distribution of pulp fibre discharged from a paper mill at Boyer in the upper estuary. Contributions from other sources of extractable organics, such as hydrocarbons and terrestrial plant and animal faecal matter from stormwater and creeks were qualitatively evaluated. On the basis of the distribution of the faecal biomarker coprostanol, the mid estuary and parts of the upper estuary (from Newtown Bay to Taroona) are severely contaminated by sewage. Pollution from pulp fibre is worst in the upper estuary and concentrations of pulp-fibre biomarkers decrease downstream. Sediments of the lower estuary (south of Taroona) have biomarker distributions more typical of open marine systems with little evidence of pulp fibre. There is, however, evidence of low concentrations of faecal pollution in the lower estuary.

Full textAbstract:
Viburnum tinus L., commonly known as laurustinus, is an ornamental shrub that is widely used as a garden plant and flower crop. V. tinus is popular because of its desirable characteristics such as evergreen foliage, tolerance to pruning, winter blooms, and its adaptation to cold temperate zones. It is also relatively easy to grow and is commonly used as a windbreak. Infection of this ornamental species by Alfalfa mosaic virus (AMV) has been associated with yellow mottling or variegated leaf coloring, including light green and white, and has been referred to as the “Viburnum Calico” (1,4). In April 2011, at the onset of winter in the Southern Hemisphere, intense yellow spotting and mottling was observed on V. tinus leaves in the San Joaquin Campus at Pontificia Universidad Catolica de Chile. Presence of Aphis spiraecola Patch was observed on the shrubs, however, in the area it is also common to find other aphid species such as Toxoptera aurantii (Boyer de Fonscolombe) and A. fabae Scopoli. Leaf tissue samples from 10 asymptomatic and 10 symptomatic plants were examined for the presence of AMV by tissue-blot immunoassay with a commercially available polyclonal antibody (Agdia Inc., Elkhart, IN) along with the Goat affinity purified anti-rabbit IgG conjugated (Whole Molecule) (Molecular Probes, Invitrogen Corp., Carlsbad, CA). First-strand cDNA synthesis and PCR were performed with specific primers CP-AMV1 and CP-AMV2 (3). AMV was detected in all symptomatic leaves and also in two of the asymptomatic tissue analyzed by tissue blot assay. Reverse transcription (RT)-PCR produced 753-bp amplicons in all samples that were positive to AMV by tissue printing. No amplification product was observed when water control or seronegative samples were used as templates in the RT-PCR assays. Two amplicons were directly sequenced in both directions to confirm the identification of AMV in the leaf samples. The sequences obtained were homologous and BLASTN analysis of the submitted sequence (GenBank Accession No. JN040542) showed 99% nucleotide sequence identity to an AMV isolate described from Nicotiana tabacum L. (GenBank Accession No. FJ527749). These results demonstrate the presence of AMV in V. tinus in Chile. This pathogen has also been described to be affecting V. tinus in France (1) and V. lucidum Mill. in Spain (2). In Chile, V. tinum is increasingly grown as an ornamental plant. Therefore, care should be taken to ensure that the propagative materials of V. tinum are devoid of AMV infection to prevent further spread of this virus. References: (1) L. Cardin et al.

Revista Brasileira de Geografia Física 14, no. 2 (June 16, 2021): 784. http://dx.doi.org/10.26848/rbgf.v14.2.p784-800.
Full textAbstract:
A Copernicia prunifera (Mill.) H.E.Moore é uma palmeira nativa do Brasil que é alvo do extrativismo anual da sua folha para retirada do pó e produção da cera, um produto muito comercializado nacional e internacionalmente. Essa palmeira vem sofrendo com a ameaça da Cryptostegia madagascariensis Bojer, espécie nativa da ilha de Madagascar, África. Essa planta, é considerada invasora no semiárido brasileiro, principalmente no bioma Caatinga, devido a sua facilidade de formar densas populações. O objetivo desse trabalho é comparar a estrutura fitossociológica de duas áreas de Caatinga com atividade extrativista da folha da Copernicia prunifera (Mill.) H.E.Moore e com a presença de Cryptostegia madagascariensis Bojer. Assim, foram selecionadas duas áreas, Área I – atividade extrativista intensiva das folhas da Copernicia prunifera (Mill.) H.E.Moore, Área II – não possui atividade extrativista intensiva. Para análise fitossociológica utilizou-se o método de parcelas, e catalogados os indivíduos com circunferência a altura do peito maior ou igual a 5 cm e altura maior ou igual a 1 m. Para a avaliação das comunidades vegetais, foram analisados os parâmetros fitossociológicos convencionais, e os índices de Similaridade, Diversidade, Equabilidade e Impacto Ambiental de Exóticas. Como resultado, foram inventariados 2.567 indivíduos pertencentes a 21 famílias, 28 gêneros e 39 espécies, das quais 21 são nativas, 17 endêmicas, 1 cultivada e 1 naturalizada, percebeu-se também que a diversidade na Área I foi menor quando comparada ao Área II. Assim, conclui-se que a presença da Cryptostegia madagascariensis Bojer associada à atividade extrativista intensiva reduz número de gêneros, espécies e famílias na Caatinga.Palavras-chave: Extrativismo, Semiárido, Fitodiversidade, Impacto Ambiental de Exóticas. Phytosociology of Two Caatinga Woods Used for Leaf Extraction of Copernicia prunifera (Mill.) H.E.Moore and Infested by Cryptostegia madagascariensis Bojer A B S T R A C TThe Copernicia prunifera (Mill.) H.E.Moore is a palm tree native to Brazil that is the target of the annual extractivism of its leaf for dust removal and wax production, a product very commercialized nationally and internationally. This palm has been suffering from the threat of Cryptostegia madagascariensis Bojer, a species native to the island of Madagascar, Africa. This plant is considered invasive in the Brazilian semiarid, mainly in the Caatinga biome, due to its ease of forming dense populations. The objective of this work is to compare the phytosociological structure of two areas of Caatinga with different degrees of extractive activity, leaves of Copernicia prunifera (Mill.) H.E.Moore and infestation by Cryptostegia madagascariensis Bojer in the municipality of Pacatuba - Ceará, Brazil. Thus, two areas were selected, Area I - intensive extractive activity of the leaves of Copernicia prunifera (Mill.) H.E.Moore, Area II - does not have intensive extractive activity. For phytosociological analysis, the plots method was used, and individuals with circumference greater than or equal to 5 cm and height greater than or equal to 1 m were cataloged. For the evaluation of plant communities, conventional phytosociological parameters were analyzed, along with the Similarity, Diversity, Equability and Environmental Impact of Exotics. As a result, 2,567 individuals belonging to 21 families, 28 genera and 39 species were inventoried, of which 21 are native, 17 endemic, 1 cultivated and 1 naturalized, it was also noticed that the diversity in Area I was lower when compared to Area II. Thus, it is concluded that the presence of Cryptostegia madagascariensis Bojer associated with intensive extractive activity reduces the number of genera, species and families in the Caatinga.Keywords: Extractivism, Semiarid, Phytodiversity, Environmental Impact of Exotics.

Full textAbstract:
The objective of this experiment was to evaluate the effect of 2 feeding systems and 5 breeding groups on the growth performance, biometric features, and stomach morphology of feedlot goat kids. The experiment utilized gender as a randomized blocking factor in a 5 × 2 factorial scheme. The study goats were from the Alpine, Anglo-Nubian, 1/2 Boer x Alpine, 3/4 Boer x Alpine, and 7/8 Boer x Alpine breeds. Half of the goats were fed an experimental diet, whereas the other half were given the same diet supplemented with 1.5 L milk daily. The kids were slaughtered after they attained 30 kg body weight. The 1/2 Boer x Alpine goats showed superior growth performance because they exhibiting considerable heterosis. These animals are especially easy to use given that there is no need to maintain cross-bred females (½ Boer x Alpine e ¾ Boer x Alpine) in the flock. Using milk in the feed the animals does not adversely affect growth performance or biometric features. Moreover, it helps to reduce the total weight of the stomach and leads to a 51.39% savings on feed. Dietary supplementation of milk in goat feed is recommended so long as there is excess milk available on the property.

Full textAbstract:
Sixty goats (20 Alpine, 18 Anglo-Nubian, and 22 crossbred Boer), with average body weight 49.33 ± 1.41 kg, were raised on Panicum maximum cv. Tobiatã pasture with two different levels of concentrate supplementation, 300 (SL30) and 600 g kg-1 (SL60) of the daily requirements, and evaluated from the pre-mating season until an average of 110 days of lactation. Milk controls were performed every 14 days. The following milk production curve parameters were estimated: time to reach peak milk production (TP), peak milk production (PP) and milk production during the first 110 days of lactation (MP). The following milk components were determined: fat, protein, lactose, total solids (TS), defatted dry extract (DDE), urea nitrogen (UN) concentrations, and somatic cell count (SCC). Goat prolificacy and birth weight of the kids were also determined. Breed affected the lactation curve, with Alpine and Anglo- Nubian goats presenting higher TP, PP, and MP. Protein, TS, and DDE concentrations were also affected by breed, being higher for crossbred Boer goats. Milk fat, lactose concentrations, and the log of SCC were affected by the concentrate supplementation level, being higher for SL30, as well as by the breed, with crossbred Boer goats presenting higher fat concentrations and log of SCC, and crossbred Boer and Alpine goats presenting higher lactose concentrations. UN was affected by the stage of lactation. Prolificacy and birth weight were affected by breed and concentrate supplementation level, being higher for Anglo-Nubian and crossbred Boer goats with SL60. Kids from single births presented higher birth weights. The Anglo-Nubian breed presented good milk production and the best body condition, which might indicate the effectiveness of this production system, SL60 supplementation resulted in higher birth weight and prolificacy.

Full textAbstract:
In dairy goats, the low average daily gain and the high conversion ratio for milk and concentrate of the kids mean that their sale price does not offset the costs generated. The hypothesis proposes that a crossbreeding of the Murciano-Granadina breed (MG) with the Boer breed (MG×Boer) will improve the profitability of the kids sold. Thus, the effect of two different groups of kids (purebred MG and crossbred MG×Boer) on birth weight (BW), mortality, average daily gain (ADG), the time for minimum slaughter weight (7 kg) and its variation factors were studied. MG×Boer kids had a 27% greater BW than purebred MG kids (2885 ± 84 g and 2275 ± 74 g, respectively), similar ADG (156 ± 6 g and 142 ± 6 g, respectively) and mortality (18% and 20%, respectively), and reached minimum slaughter weight a week sooner. ADG was less and less as the lactation period progressed due to a lower milk consumption and milk energy value, which highlights the importance of providing a concentrate that will compensate for this reduced energy content. In conclusion, the results show that MG×Boer crossbred kids reached the minimum slaughter weight a week earlier than purebred MG kids, and highlighted the improvement of farm profitability through the increase of milk sold and the need to provide a concentrate feed to enhance the growth of the kids.

Full textAbstract:
The sugarcane borer, Diatraea saccharalis (Fabr.) is the main sugarcane pest in Brazil. In the State of São Paulo, the main active population control of D. saccharalis is by inundative releases of the exotic parasitoid, Cotesia flavipes (Cam.). However, the production of C. flavipes in sugar mills entails costs and few studies have evaluated the effects of native predators on sugarcane borer populations. Using a simple colony translocation method, we evaluated the effect of fire ants (Solenopsis spp.) on population densities of D. saccharalis and concurrently upon rates of parasitism by classical biological control agents in the São João sugar mill in the State of São Paulo, Brazil. The translocation technique proved to be feasible and economically possible. Sugarcane borers were sampled in each of the 5 areas for each treatment in two 1.4 x 5.0 m (7 m²) points (sample size), by opening and visually examining all canes. The average numbers and its respective standard deviations (SD) for D. saccharalis population densities before and after colony translocations considering 0, 5, 10 and 15 colonies added per 0.5 ha were, 9.2 ± 5.9, 8.4 ± 3.4, 9.0 ± 6.9, 9.4 ± 8.1 and 3.2 ± 1.8, 2.8 ± 2.7, 2.6 ± 1.5, 3.8 ± 2.8, respectively. However, we detected no significant changes in sugarcane borer densities with respect to ant colony densities over a two-week period, none of which were greater than for no colony additions. No effects of colony translocations on parasitism rates of braconid and tachinid parasitoids on D. saccharalis were detected. Thus, although the translocation technique was economically feasible, no reductions of D. saccharalis densities were produced by colony additions, and may not be a viable alternative for D. saccharalis population reduction, especially at the low population levels which prevail in Brazil.

O objetivo deste estudo foi avaliar os inseticidas deltametrina e carbaril, de modo a abranger seus resíduos em dois sistemas de condução da cultura de tomate estaqueado (linha dupla, plantio comercial e linha simples, plantio experimental) e sua eficiência no controle da broca-pequena-do-fruto, a determinação dos resíduos nos substratos: frutos (visando à proteção à saúde pública), folhas e solo (como uma possível fonte de contaminação ambiental), a comparação dos níveis de resíduos encontrados nesses diferentes sistemas de condução, o controle obtido com os dois inseticidas e sistemas de condução e a comparação dos níveis de resíduos dos frutos com os LMRs (Limites Máximo de Resíduo) e intervalo de segurança estabelecidos pela legislação brasileira. O experimento foi conduzido no Município de Piedade, no Estado de São Paulo, Brasil. Consistiu em cinco tratamentos: (1) nove aplicações de deltametrina (Decis 25 CE) no plantio linha simples, (2) nove aplicações de carbarill (Sevin 480 SC) no plantio linha simples, (3) nove aplicações de deltametrina (Decis 25 CE) em linha dupla, (4) nove aplicações de carbaril (Sevin 480 SC) no plantio linha dupla e (5) controle. A primeira aplicação foi feita no início da fase de maturação do fruto e as seguintes em intervalos subseqüentes de 7 dias. As amostras de frutos foram colhidas com (-1), zero, 3, 5 e 10 dias após a última aplicação. As amostras de folha e solo foram coletadas com (-1), zero, 1, 3, 10 e 20 dias após a última aplicação. O método analítico consistiu na extração dos resíduos com acetato de etila, limpeza dos extratos em cromatografia de permeação em gel (GPC), e determinação quantitativa em cromatógrafo de gás equipado com detector de captura de elétrons (GLC/ECD) (deltametrina) e em cromatógrafo de gás equipado com detector seletivo de massas (GLC/MSD). Os resultados mostraram que os resíduos de deltametrina nos frutos no plantio comercial estavam abaixo de seu LMR ao final do intervalo de segurança; o mesmo não ocorreu com o carbaril que nos dois sistemas de condução, apresentou resíduos superiores ao seu LMR. Os resíduos maiores foram encontrados nas folhas, para ambos os inseticidas, constituindo assim, estas, uma possível fonte de contaminação ambiental. Os resíduos encontrados no solo foram baixos, no caso da deltametrina se aproximaram dos valores encontrados para o fruto e os de carbaril foram ainda menores que os do fruto, mostrando um baixo escorrimento da calda de saturação e conseqüentemente, um baixo potencial de contaminação do solo. O plantio experimental (linha simples) apresentou resíduos sempre maiores que o plantio comercial (linha dupla), sendo, em conseqüência, melhor o controle da praga nesses tratamentos.The objective of this study was to evaluate the insecticides deltamethrin and carbaryl, in order to study their residues, in two cultivation systems of staked tomato crop: experimental cultivation (single line) and commercial cultivation (double line) and their efficiency in the control of the fruit small borer, Neouleucinodes elegantalis (Guenée, 1854) (Lepidoptera: Crambidae), the determination of the residues in fruits (aiming the protection of public health), leaves and soil (like a possible source of environmental contamination), the comparison of residues found in these two different systems of cultivation, the control achieved with both insecticides and systems of cultivation and the comparison of the residues in fruits with the MRLs (Maximum Residue Levels) and safety intervals established by Brazilian legislation. The experiment was conducted Piedade County in the State of São Paulo, Brazil. It consisted of five treatments: (1) nine applications of deltamethrin (Decis 25 CE) in single line, (2) nine applications of carbaryl (Sevin 480 SC) in single line, (3) nine applications of deltamethrin (Decis 25 CE) in double line, (4) nine applications of carbaryl (Sevin 480 SC) in double line and (5) control. The first application was made at the begining of the fruit maturation stage, and the following ones in 7 days period scheduled. Fruit samples were collected one day before the last application (-1 day) and zero, 3, 5 and 10 days after the last application. Leaf and soil samples were collected one day before the last application (-1 day) and zero, 1, 3, 10 and 20 days after the last application. The analytical method consisted by extraction of residues with ethyl acetate, clean-up of the extracts by gel permeation chromatograph (GPC), and quantitative determination by gas chromatograph equipped with electron capture detector (GLC/ECD) (deltamethrin) and by gas chromatograph equipped with mass selective detector (GLC/MSD). The results showed that deltamethrin residues in fruits from commercial cultivation system (double line) were below MRL at the end of safety interval; as for carbaril residues they were above MRL in fruits from both cultivation systems. Higher residues were found on leaves, for both insecticides, being considered this as a possible source of environmental contamination. Soil residues were lower; as for deltamethrin the levels were similar to fruit, but for carbaril they were lower in as compared to fruits showing low drift from the saturated foliage and consequently, low potential of soil contamination. The experimental cultivation system (single line) always showed higher residue levels for both insecticides than the commercial one (double line), being, in consequence, better the insect pest control in these treatments.

At the Pine Ridge winery in Napa Valley, California, a sign lists six essential steps in wine production. The first step reads . . . Determine the site—prepare the land, terrace the slopes for erosion control, provide drainage and manage soil biodiversity. . . . Determining the site means gathering comprehensive data on the local climate, topography, and geology, as well as the main soil types and their distribution. Traditionally, site determination was done using the knowledge and experience of individuals. Now it is possible to combine an expert’s knowledge with digital data on climate, parent material, topography, and soils in a GIS format to assess the biophysical suitability of land for wine grapes. Viticultural and soil experts together identify the key properties and assign weightings to these properties. An example of an Analytical Hierarchy Process is shown in figure 8.1. In this approach, both objective and subjective data were pooled and evaluated to decide the suitability of land for viticulture in West Gippsland, Victoria. In this region with a relatively uniform, mild climate, soil was given a 70% weighting, and the important soil properties were identified as depth, drainage, sodicity, texture, and pH. But in other areas, with another group of experts, a different set of key properties and weightings may well be identified. For example, a similar approach used in Virginia, in the United States, gave only a 25% weighting to soil and 30% to elevation (which affected temperature, a critical factor governing growth rate and ripening) (Boyer and Wolf 2000). This kind of approach can be refined to indicate site suitability for a particular variety within a region of given macroclimate. For example, Barbeau et al. (1998) assessed the suitability of sites in the Loire Valley, France, for the cultivar Cabernet Franc, using an index of “precocity.” Such an index is related to the ability of the fruit to accumulate sugar and anthocyanins and to attain a favorable acidity.

Full textAbstract:
Annual plants have developed a range of different mechanisms to avoid flowering (exposure of reproductive organs to the environment) under adverse environmental conditions. Seasonal environmental events such as gradual changes in day length and temperature affect the timing of transition to flowering in many annual and perennial plants. Research in Arabidopsis and additional species suggest that some environmental signals converge on transcriptional regulation of common floral integrators such as FLOWERING LOCUS T (FT). Here we studied environmental induction of flowering in the model legume Medicago truncatula. Similarly to Arabidopsis, the transition to flowering in M. truncatula is hastened by long photoperiods and long periods of vernalization (4°C for 2-3 weeks). Ecotypes collected in Israel retain a vernalization response even though winter temperatures are way above 4°C. Here we show that this species is also highly responsive (flowers earlier) to mild ambient temperatures up to 19°C simulating winter conditions in its natural habitat. Physiological experiments allowed us to time the transition to flowering due to low temperatures, and to compare it to vernalization. We have made use of natural variation, and induced mutants to identify key genes involved in this process, and we provide here data suggesting that an FT gene in M.truncatula is transcriptionally regulated by different environmental cues. Flowering time was found to be correlated with MtFTA and MtFTB expression levels. Mutation in the MtFTA gene showed a late flowering phenotype, while over-expressing MtFTA in Arabidopsis complemented the ft- phenotype. We found that combination of 4°C and 12°C resulted in a synergistic increase in MtFTB expression, while combining 4°C and long photoperiods caused a synergistic increase in MtFTA expression. These results suggest that the two vernalization temperatures work through distinct mechanisms. The early flowering kalil mutant expressed higher levels of MtFTA and not MtFTB suggesting that the KALIL protein represses MtFTA specifically. The desert ecotype Sde Boker flowers earlier in response to short treatments of 8-12oc vernalization and expresses higher levels of MtFTA. This suggests a possible mechanism this desert ecotype developed to flower as fast as possible and finish its growth cycle before the dry period. MtFTA and FT expression are induced by common environmental cues in each species, and expression is repressed under short days. Replacing FT with the MtFTA gene (including regulatory elements) caused high MtFTA expression and early flowering under short days suggesting that the mechanism used to repress flowering under short days has diversified between the two species.The circadian regulated gene, GIGANTEA (GI) encodes a unique protein in Arabidopsis that is involved in flowering mechanism. In this research we characterized how the expression of the M.truncatula GI ortholog is regulated by light and temperature in comparison to its regulation in Arabidopsis. In Arabidopsis GI was found to be involved in temperature compensation to the clock. In addition, GI was found to be involved in mediating the effect of temperature on flowering time. We tested the influence of cold temperature on the MtGI gene in M.truncatula and found correlation between MtGI levels and extended periods of 12°C treatment. MtGI elevation that was found mostly after plants were removed from the cold influence preceded the induction of MtFT expression. This data suggests that MtGI might be involved in 12°C cold perception with respect to flowering in M.truncatula. GI seems to integrate diverse environmental inputs and translates them to the proper physiological and developmental outputs, acting through several different pathways. These research enabled to correlate between temperature and circadian clock in M.truncatula and achieved a better understanding of the flowering mechanism of this species.
