Testo completoThe objective of this work was to determine the effect of heat treatment with or without fungicide on the quality and potential storage of Murcott tangor. The cold storage for long time increases the incidence of chilling injury and decay of Murcott tangor. Fruit were stored under two cold storage temperatures: 1 and 4°C, and different treatments were applied in each one: 1) Control (fruit without fungicide, just with 25°C water dip/2min), 2) Fruit with 25°C imazalil (50mg L-1) dip/2 min, 3) Fruit with 53°C imazalil (50mg L-1) dip/2 min, 4) Fruit just with 53°C water dip/2min. All fruit were stored (under temperatures 1°C and 4°C) during 8 weeks. Every two weeks analysis were determining the physico-chemicals properties and the sensorial characteristics. Reduction of storage temperature and heat treatments had low influence over physicochemicals properties. The 1°C stored fruit presented chilling injury symptoms after 6 weeks. The heat treated fruit before storage showed reduction on chilling injury levels but increased weight loss. The fungicide dips did not have effects over chilling injury and decay incidence neither on physico-chemicals properties. The sensorial characteristics decreased along the period. Heat treated and 1°C stored tangor `Murcott` presented better on the sensorial evaluations.

Testo completoThe objectives of this work were to determine the effect of minimally processing and the storage temperature on the physiology of fresh-cut tangor Murcott and to determine the edible coatings that maintain the microbiological, sensorial and physico-chemical qualities of fresh-cut tangor Murcott. In the first experiment two processing levels (peeled fruits and segments) and five storage temperatures (1º, 6º, 11º, 21º and 31ºC) were tested. Whole fruits were used as control. In the second experiment the segments were treated with several edible coatings and stored under two temperatures (6º and 12ºC). The edible coatings were: gelatin 4% w/w, gelatin 8% w/w, whey protein 8% w/w and paraffin wax emulsion. Segments without recovering were used as control. In the first experiment the respiratory rate and the ethylene production were determined every hour for 10 hours and then, every day for 7 days. The temperature quotients (Q10) were also determined. In the second experiment were determined: the physico-chemical properties every two day for six days; the respiratory rate daily for eight days; the microbiological analysis on the fourth and seventh days of storage; and the sensorial analysis on the fourth day of storage. The storage temperature and the processing level did influence the respiratory rate. The ethylene levels were low and inconstant during the study. The edible coatings were little effective on reducing the respiratory rate and on maintaining the physico-chemical, microbiological and sensorial properties of fresh-cut tangor Murcott.

Testo completoThe demand for fresh fruits with good characteristics to exportation has increased, being mostly dependent on the improvement of fruit quality. In this sense, the adequacy of the operations related to production and post-harvest is crucial to make the Brazilian citrus fruit more competitive in foreign markets. Due to the large part of Brazilian citrus growing area is located in the tropical, citrus fruit reaches full internal maturity, while the peel remains partially green, making them unacceptable for the demanding fresh fruit markets. Thus, there is a necessity to study methods and more suitable conditions for the degreening of post-harvest fruit in our climatic conditions and varieties. This study was based on the technique of post-harvest degreening of \'Murcott\' and \'Valencia\', involving the application of ethylene in liquid and gaseous form (chamber). The concentrations used were 0 to 8000 mg L-1 of ethephon by immersion (3 minutes) and 0.0, 0.25, 0.5, 0.75 and 1.0 L m-3 of ethylene applied inside the chamber for 24 to 120 hours of exposure and 15 to 30ºC and 90% RH. The best conditions for degreening were defined and later, part of the fruits was for 3 days at 25ºC and 80% RH, simulating the commercialization, and the other part was stored under refrigeration (5ºC) with 90% RH for 30 days, and after that, 3 days at 25ºC and 80% RH, simulating the commercialization. The effect of cold storage of the fruit before the degreening inside the chamber was also evaluated. The fruits were evaluated right after the applications, the first simulation of commercialization, the cooling and the second simulation. The condition of 0.5 L m-3 for 96 hours at 25ºC was the most efficient way to improve fruit color. Respiratory rate and ethylene production increased with the dosage of ethylene used. The increased activity of chlorophyllase was followed by decrease in chlorophyll content, while the carotenoid content remained constant. As for the internal features, significant changes in the treatments were not observed. It was found that refrigerated storage after degreening do not interfere on the development of the fruits peal color, neither affecting their quality. Beyond that the process of degreening after cooling is effective for changing the color of both studied varieties.

Testo completoThe experiments were conducted from August 2001 to August 2002 in the post-harvest Physiology Laboratory, Department of Biology, ESALQ-USP. It was checked the isolated effect of gibberellic acid, 1-methylcyclopropene and aminoethoxyvinilglycine, and also the combinations of 1-MCP with GA3 and AVG with GA3, on Murcott tangor and Tahiti lime post-harvest. The cultivars were chosen because of their potential, both for the internal market as for fresh fruit exportation. The following concentrations were applied: GA3 at 20 mg L -1 ; 1-MCP at 0.1, 0.5 and 1.0 mL L -1 ; AVG at 10, 50 and 100 mg L -1 and the combinations of 1-MCP at 0.5 mL L -1 with GA3 at 20 mg L -1 and AVG at 50 mg L -1 with GA3 at 20 mg L -1 , and the control. The fruits were exposed to 1-MCP gas during 12 h in hermetic boxes at 20 o C. AVG and GA3 were applied dipping the fruits, for a minute, in solutions with the mentioned concentrations. In combinations, GA3 was applied after the treatments with 1-MCP or AVG. The experimental design was totally randomized factorial to check the action of 1-MCP and AVG on Murcott tangor and Tahiti lime. For the combinations of 1- MCP+GA3 and AVG+GA3, totally randomized design was used with time subdivided parcels. It was determined the evolution in the peel color (L, C* e h o ), the levels of total soluble solids ( o Brix), total titriable acidity (%), vitamin C, mass loss (%), juice content (%) and respiratory rate of the fruits under cold storage and after 3 days at 25 o C. The results were submitted to regression analysis. 1-MCP doesnt have any effect on the peel color, in late application, on tangor Murcott. The 1-MCP at 0.5 mL L -1 was enough to reduce the respiratory rate and the waste of C vitamin. The physic-chemical characteristics were kept suitable for the consumption during 45 days of cold storage. The AVG, in post-harvest application, enhanced the peel color intensity of Murcott tangor, decreased the waste of total soluble solids, the respiratory rate and didnt affect the total titrable acidity. The combinations of 1-MCP and AVG with GA3 didnt have any effect on the peel color of Murcott tangor, after an advanced stage of peel coloration. The combinations didnt affect the levels of total titrable acidity, C vitamin, mass loss and respiratory rate of Murcott tangor. In relation to Tahiti lime, the treatment with 1-MCP at 0.5 or 1.0 mL L -1 delayed changes in the peel color (color croma and angle), promoted higher concentration of total soluble solids and decreased the range of ratio variation. The AVG didnt prevent peel color change, however it decreased the waste of TSS and of TTA; it didnt affect the respiratory rate and the level of C vitamin. The combination of 1-MCP+GA3 delayed the evolution in the change of peel color during 60 days. The level of C vitamin was kept high. There werent changes in the respiratory rate and in juice content Tahiti lime.

Testo completoThe objective of this study was to test an alternative management in a conventional orchard of Murcott tangor (Citrus reticulata, Blanco X Citrus sinensis, Osbeck) grafted on rangpur lime (Citrus limonia, Osbeck) using fermented compost Bokashi, in order to evaluate its effect on soil decompaction, root colonization of indigenous arbuscular mycorrhizal fungi (AMF), nutritional performance, yield and technological characteristics of fruits. The experiment was set by separating one hectare plot in a ten year old yielding orchard, where chemicals fertilizers and pesticides, including herbicides, were discontinued and replacing them by sources of low solubility nutrients and alternative pest control, with the purpose to encouraging the biological interactions, mainly mycorrhizal associations. To stimulate vegetal covering, a fermented compost Bokashi was applied on the spontaneous vegetation of the row e interrow, mechanical clearing was used, and the area was designated alternative treatment. An equivalent and adjoining area, where conventional cultural and phythosanitary treatments were maintained was used for comparative purposes, and was designated conventional treatment. The parameters chosen for comparison were: soil resistance to penetration, surface root density, colonization of indigenous arbuscular mycorrhizal fungi, as well as amount of viable spores in the soil, analysis of foliar nutrient content, and fruit yield and quality. Ten plots of 3 plants per each treatment were evaluated. The alternative management with application of fermented compost Bokashi on the spontaneous vegetation on the interrow provided a 107.5% increase in vegetal covering, mainly grasses, measured in January 2005, which decreased soil resistance to penetration and resulted in an improvement in soil compaction state as compared with the conventional treatment. Also, there were an improved development of surface root systems, a higher rate of root colonization of indigenous arbuscular mycorrhizal fungi (AMF) in plants of Murcott tangor, averaging 10% higher and, consequently, a higher amount of viable spores in the soil, an average of 23% higher than of the conventional treatment. In nutritional terms, the input of K in the alternative treatment was not enough to supply adequately the needs of the plants, indicating that more attention is required in relation to this nutrient in alternative proposals of citrus management. The foliar content of B was shown to be significantly higher and at increasing rates along the experiment, reaching levels 280% higher than those of the conventional treatment, having reached contents of up to 161.35 mg.kg-1, a highly desirable result for citrus nutrition. Despite the initial yield decrease, the alternative treatment showed a higher fruit mass per plant in the last evaluation in August 2004, i.e. 58.2 kg.plant-1 against 42.9 kg.plant-1 in the conventional treatment, even though fruit size and total acidity were impaired by K deficiency. This shows that, in older aged orchard, an alternative management should be introduced gradually. Subsequent appraisals showed that the alternative treatment provide a better equilibrium in the population of Orthezia praelonga, i.e. 0.54% of attacked plants against 14.06% in the conventional treatment.

Testo completoAlternate bearing, small fruits and fruit set are problems of some citrus cultivars. This research was performed at 2000/2001, in comercial orchards of 'Murcott' mandarin hybrid (Citrus reticulata Blanco x Citrus sinensis L. Osbeck) and 'Tahiti' lime (Citrus latifolia Tanaka), with 10 and 8 years old, located in Mogi-Mirim and Taquaritinga-SP, respectively. In the first trial, it was evaluated the effects of bioregulators ethylclozate 200 mg.L-1, Phenothiol 10 mg.L-1, Fengib 1 ml.L-1, GA3 20 mg.L-1, 2,4-D 8 mg.L-1 and GA3 20 mg.L-1 + 2,4-D 8 mg.L-1 on the fruit thinning and the fruit size of 'Murcott' mandarin hybrid. The treatments were sprayed on whole trees after total petal fall (fruits with approximately 6 mm of diameter), at a rate of 6 litres per tree. The number of fruits per tree and yield (kg/tree) were not affected by the treatments. GA3 20 mg.L-1 + 2,4-D 8 mg.L-1, GA3 20 mg.L-1 and Fenotiol 10 mg.L-1 increased the final fruit size (3.4%; 3.0% and 3.0%), the final fruit weight (7.8%; 8.8% and 9.5%) and the number of fruits of larger comercial size class. The treatments didn´t affected juice content, total soluble solids, acidity, pH, juice colour and peel colour. The CO2 assimilation, transpiration, stomatal conductance and chlorophyll content were not affected by the treatments. In the second trial, it was evaluated the effects of bioregulators 3,5,6-TPA 15 mg.L-1, 2,4-DP 50 mg.L-1, Phenothiol 20 mg.L-1, ethephon 200 mg.L-1 and ethylclozate 200 mg.L-1 on the fruit thinning and the fruit size of 'Murcott' mandarin hybrid. The treatments were sprayed on whole trees after physiological fruit drop (fruits with approximately 22 mm of diameter), at a rate of 6 litres per tree. 3,5,6-TPA 15 mg.L-1, ethephon 200 mg.L-1 and Phenothiol 20 mg.L-1 increased the final fruit size (7.0%; 6.8% and 4.4%), the final fruit weight (19.1%; 17.3% and 8.7%) and the number of fruits of larger comercial size class. However, 3,5,6-TPA 15 mg.L-1 ethephon 200 mg.L-1 decreased the number of fruits per tree (57.1% e 47.9%) and yield (47.8% e 37.5%), in kg/tree. Phenotiol decreased by 0,4 the total soluble solids. The treatments didn´t affected juice content, acidity, pH, juice colour and peel colour. The CO2 assimilation, transpiration, stomatal conductance and chlorophyll content were not affected by the treatments. In the third trial, it was evaluated the effects of bioregulators Phenothiol 10 mg.L-1; Fengib 1 ml.L-1; Brassinolide 0.015 mg.L-1; GA3 20 mg.L-1; 2,4-D 8 mg.L-1 and GA3 20 mg.L-1 + 2,4-D 8 mg.L-1 on the fruit set of 'Tahiti' lime. The bioregulators didn´t change the vegetative growth. The treatments with GA3 (GA3 20 mg.L-1, Fengib 1 ml.L-1 e GA3 20 mg.L-1 + 2,4-D 8 mg.L-1) increased the fruit set. The best treatment was GA3 20 mg.L-1 + 2,4-D 8 mg.L-1 that promoted 21.3% of fruit set against 5.9% by control. The fruit set was coupled to increases in chlorophyll content and CO2 assimilation by leaves of 'Tahiti' lime.

Testo completoThe citrus fruit processing is justified for the difficulty of peeling of these fruits. Studies of peeling of \'Pera\' sweet orange fruit accomplished at ESALQ-USP are showing the potential of the use of the hydrothermal treatment to facilitate the peeling of this variety. The oranges are immersed in hot water at 50ºC for 8 minutes. This process to make easy the peeling and it doesn\'t affect the quality of the fruit. However, it is necessary to study other immersion times to make flexible the use of this technique in industrial scale, as well as to extend it for other varieties. The purpose of this work was to adapt the technology of peeling of citric fruits for the use of the hydrothermal treatment, as well as to evaluate the influence of the hydrothermal treatment in the physiological, physicochemical, microbiologic and sensorial qualities of \'Pera\' sweet orange, \'Valencia\' sweet orange and \'Murcott\' tangor. The peeling time, the yield of marketable fruits and the internal fruit temperature were also evaluated during the treatment. Fruits were washed, sanitized, cooled at 5ºC for 12 hours, submitted to hydrothermal treatment and peeled. The hydrothermal treatment consisted of putting fruits in water-bath at 50ºC for 5 (only for \'Murcott\' tangor), 10, 15, 20, 25 and 30 minutes. Then, fruits were peeled by first opening a gap on the peduncular region with a knife and then, the flavedo was removed, manually, with the albedo. Fruits with no hydrothermal treatment (control) were peeled by first removing the flavedo and then, the albedo was removed carefully to cause the less of injuries possible. The fruits were analyzed for six days of storage at 5ºC. The experiments were carried out separately for each citric fruit and in agreement with each analysis type. The experimental designs used were completely randomized and in randomized blocks, appropriate for each analyzed variable. Hydrothermal treatment caused changes in respiratory activity just in first hours after treatment. Internal fruit temperature (evaluated at 2 cm depth in relation to the epicarp) after 30 minutes of treatment reached 35ºC approximately, temperature commonly observed in some stages of the commercialization\'s chain of the fruits. The external coloration of the oranges without treatment presented larger value of brightness (L) when compared to the treated fruits. There were no changes in the others physicochemicals and microbiologics characteristics of the fruits. The treatment did not change the flavor and it improved the appearance in relation to the fruits without treatment due to the lower albedo residue in the fruits. Besides, the treatment decreased in up to 78% the peeling time of the treated fruits for the \'Pera\' sweet orange, in up to 75% for the \'Valencia\' sweet orange and in up to 57% for the \'Murcott\' tangor, when compared to the fruits without treatment, and it increased the yield of marketable fruits. The hydrothermal treatment accomplished up to 30 minutes at 50ºC can be used as peeling technique for \'Pera\' sweet orange, \'Valencia\' sweet orange and \'Murcott\' tangor.

Resumo: O cádmio é considerado um elemento tóxico, pois afeta severamente a vida de muitos organismos, mesmo em baixas concentrações. Na célula, ele interage com proteínas e ácidos nucléicos e com isso, enzimas elou membranas são afetadas, interferindo em várias vias metabólicas importantes. Com o intuito de verificar os efeitos desse metal pesado na morfologia de células vegetais, foram utilizadas suspensões celulares de cana-de-açúcar e laranja, que receberam soluções de cloreto de cádmio 8f.1M durante 4 a 72h de incubação. Os materiais foram fixados para a microscopia de luz, microscopia eletrônica de transmissão e de varredura. Foram ainda retiradas amostras para dosagens de proteínas e açúcares em cada experimento. As suspensões celulares de cana apresentaram os maiores danos em conseqüência do tratamento sendo nítida a presença de duas regiões: uma denominada região A, com células que tiveram contato direto com o agente estressante. Nela foram observados núcleos picnóticos, paredes celulares lignificadas ou com má formação. Na outra região, denominada B e correspondente a células que se desenvolveram na presença do metal, foram notados vacúolos compartimentalizados e outras vesículas, núcleos mais descompactados e com aumento no número de nucléolos. Houve ainda um aumento aparente no tamanho e quantidade de mitocôndrias. O complexo de Golgi foi observado com maior freqüência e o retículo endoplasmático apresentou dilatação de suas cisternas. Na superfície das paredes celulares da região B foram notadas desfibrilações bastante evidentes à microscopia de luz e microscopia eletrônica de varredura, sendo ainda bem contrastadas ao microscópio eletrônico de transmissão. O tratamento com cádmio provoca alterações significativas no conteúdo de proteínas, açúcares livres e solúveis, mas não na quantidade de amido presente nas células. Essas alterações em tratamentos mais longos tendem a retomar aos valores inicialmente obtidos, indicando uma resposta das células à situação imposta. Nos tempos de tratamento e nas concentrações de cádmio utilizadas, as respostas obtidas foram mais evidentes nas células de cana-deaçúcar do que nas de laranja, tanto no que diz respeito aos danos provocados nas células, quanto às respostas das mesmas ao agente estressante
Abstract: The cadmium is considered a toxic element, because it affects severely the life of many organisms, even in low concentrations. In the cell, it interacts with proteins and nucleic acids and with this characteristic, enzymes and/or membranes are affected, interfering in several important metabolic pathways. With the intention of verifying the effects of this heavy metal on the morphology of vegetable cells, cellular suspensions of sugar-cane and orange were used, which received solutions of cadmium chloride 8J.1M during 4 to 72 hours of incubation. The materiais were fixed for light microscopy, transmission electron microscopy and scanning electron microscopy. Samples were also removed samples for protein and sugars dosages in each experimento The cellular suspensions of sugar cane presented the largest damages and as a consequence of the treatment, the presence of two clearly differentiated areas: one, denominated A area, with cells that had direct contact with the stressful agent and showed picnotic nuclei, lignified or with malformed cell walls. In the other area, denominated B and corresponding to cells that grew in the presence of the metal, with compartmentalized vacuoles and other vesicles, non-compacted and on increased number of nucleoli. There was still an apparent increase in the size and amount of mitochondria, Golgi complex, and endoplasmic reticule presenting dilation of their cisterns. On the surface of the cell walls in this area, a quite evident fibrillation was noticed with light and scanning electron microscopy, also being strongly contrasted with the transmission electron microscopy. Cadmium treatments lead to significant alterations in protein content, free and soluble sugars, but not in the quantity of starch. The alterations, found in longer treatments, tend to return to the initial values, which indicates an adaptation to the culture conditions. For the treatment periods and cadmium concentrations used, the adaptation mechanisms are more evident in sugarcane cells then in orange, not only in relation to the alterations produced but also their adaptations to the stress agent

A mancha marrom de alternaria, causada pela Alternaria alternata f. sp. citri, afeta o tangor murcote causando lesões em folhas, ramos e frutos, acarretando em desfolha e manchas que depreciam o fruto comercialmente. Os objetivos deste trabalho foram verificar o efeito do meio de cultura no isolamento, da temperatura e do fotoperíodo no crescimento micelial do patógeno, avaliar a sensibilidade do patógeno à fungicidas in vitro e estabelecer o melhor produto e dose para o controle da doença no campo. As avaliações laboratoriais constaram de avaliações de crescimento micelial, medição do tamanho de conídios, concentração de conídos/mL e avaliação de meios de culturas para isolamento do patógeno. Os resultados do teste in vitro mostraram que os ingredientes ativos trifloxystrobin, iprodione, azoxystrobin, difenoconazole, pyraclostrobin, trifloxystrobin + propiconazole e trifloxystrobin + tebuconazole inibiram completamente o crescimento micelial do patógeno. No ensaio de campo todos os tratamento foram superiores a testemunha quanto a produtividade. Concluindo que o controle da doença é recomendado independente do produto utilizado. Entre os produtos utilizados o tratamento com trifloxystrobin + propiconazole foi rentável comparando-se custo e produtividade.

‘Murcott’ tangor is a fast expanding citrus cultivar in Taiwan. This study investigates the optimum harvesting stage and harvesting index of this fruit, as well as conditions for its cold storage. The potential of application of ultraviolet light-C was also studied. Based on the results of experiments carried out in two consecutive years, the optimum harvesting period for ‘Murcott’ tangor grown in Shin-kong, Taichung was from late February to mid-April with its sugar to acid ratio reaching 18. Proper harvesting index include titratable acidity declined below 750 mg citrate/100 ml juice, sugar/acid ratio increased to 18 or higher and the Hunter “b” value is greater than 3.5. Storing fruits at 0℃and 5℃reduce decay significantly. Granulation of juice vesicles were observed in fruits stored at 5℃, 10℃ and 15℃for over two months. This disorder symptom was most sever in fruits stored at 10℃. All fruits that were stored for more than 4 months exhibit poor flavor by panel test. It was suggested that the best storage temperature for ‘Murcott’ tangor is 0℃ and its duration not exceeding three months. It was found that the relative ratio of fructose, glucose and sucrose within the total soluble solid content of fruit juice remained unchanged throughout maturation period. However, in the relative ratio of individual sugars varied after fruits were stored at different temperatures for one or more months, and such variation could not be represented by changes in the total soluble solid content. The application of ultraviolet light (254 nm, UV-C) could not maintain the green button ratio of ‘Murcott’ tangor during storage. Dosages higher than 1 KJ/m2 effectively inhibited the occurrence of penicillium rot. However, dosages higher than 5 KJ/m2 promoted the incidence of stem-end rot and skin shrinkage.

In this thesis, explore effect of different harvest maturity, storage temperature, rootstock types (Sunki, Rangpur lime), fruit size and field bagging on fruit quality of the Yilan Murcott tangor. Aspirations of the Yilan research and extension citrus industry helpful Murcott (Murcott tangor; Citrus reticulata × Citrus sinensis) was cultivated in Yilan Sanshing township and used in the following experiments. Fruit shape index was always less than 1 during development, as oblate sphere. The cumulative growth curves of the fruit were both single sigmoid growth curve. Fruit drops occurred by the late April to early June, up to 8.7% per week, while significant fruit drops also occurred at October, reaching 5.0% per week. Fruit cracking occurred mainly between September to October, up to 2.6% per week. Fruit maturity date was 293 days after anthesis, as estimated by absolute growth rate study. Yilan Murcott tangor harvest after early February total soluble solids content is up to 12 ° Brix, and hue angle is smaller than 60(orange peel), would be the appropriate harvest date (harvest maturity). The peel thickness of fruit on Sunki rootstock was significantly lower than on Rangpur lime, and no significant differences between the two. Effectively reduce the decay rate and weight loss at 1℃, to extend the storage life of Murcott tangor to three months, while the rootstocks no significantly impact on the storage life.Peel thickness and TSS/TA ratio varies with fruit size of increases to improve, but the juice percentage, flesh firmness, titratable acid content, lightness and chroma decreased with the fruit size decreasing, The greater fruit of Murcott tangor its TSS/TA is relatively high, lower titratable acid content and flavor better. Bagging Murcott will increase the peel percentage, lightness, chroma and hue angle, and reduce the juice percentage, total soluble solids, titratable acid content and TSS/TA ratio, but the fresh weight, peel thickness and flesh firmness did not affect.Early set of white paper with red wax will cause higher flesh firmness, bagging of the morning and evening periods of little influence on the rest fruit quality and no consistency.Removal of white wax paper bags, will reduce the hue angle, and improve the peel percentage, chroma and total soluble solids content (still lower than the control group), while the removal of silver black bag can reduce the peel percentage, peel thickness, lightness and hue angle, and increase the total soluble solids (still lower than the control group). Overall, Bagging does not apply to Murcott because it reduces fruit quality (low total soluble solids, low TSS/TA, and high hue angle)
