Full textThe goal of this research was to test commercially viable alternative methods to fungicides for controlling storage diseases of melons that are safe for human health and the environment. Initially, experiments were conducted on melons to develop a protocol for optimum conditions of disease development during storage for different pathogens and for different stages of fruit maturity. For all pathogens tested, the study found that humidity greater than 90% and temperatures above 20° C support infection and rapid growth of disease. Differences in the rate of infection and extent of disease development after the inoculation of different storage pathogens was observed between rockmelon and honeydew melons, indicating differences in host pathogen interactions. Among the tested pathogens, Alternaria spp. was the least aggressive in infection and disease severity, growing considerably slower than Fusarium acuminatum which was moderately aggressive and Rhizopus spp. which was very aggressive, in comparison. Green half-slip melons showed greater resistance to pathogen attack than green full-slip fruit, while yellow full-slip melons were highly susceptible to pathogen attack. Therefore, the laboratory experiments for postharvest treatments of rockmelons were performed using green full-slip fruit challenged with F. acuminatum. Evaluation of physical and safe chemical methods of postharvest treatment to control postharvest diseases of melons showed that none of the treatments alone was as effective as the commercially available fungicide. Hot water solutions of safe compounds considerably increase their efficacy against postharvest rots, however, symptoms of phytotoxicity on the rind after dipping made their use unacceptable. Iodine was the only safe chemical tested which did not cause any phytotoxicity on melons. When combined with hot water, iodine showed the best control of storage rots and was as good as the fungicides carbendazim or guazatine. Hot water iodine dipping of fruit also delayed ripening and fruit were firmer during storage for a longer period of time. Systemic acquired resistance (SAR) was evaluated as a method of controlling powdery mildew in glasshouse grown rockmelon seedlings by treating with the activators 2,6-dichloroisonicotinic acid (INA) or benzothiadiazole (BTH) or water. Increased resistance due to application of INA or BTH, was observed by the reduction of powdery mildew on pre-inoculated detached leaves and also on intact leaves from natural infections. Heightened resistance due to spraying with elicitors of SAR, was further evident by the increased activities of the pathogenesis related proteins (PR proteins), peroxidase and accumulation of phenolics or antifungal compounds during and after challenge inoculation. Field grown rockmelons were treated with INA or BTH or BABA (β-aminobutyric acid) or water at various stages of plant growth and evaluated for increased resistance against pre and postharvest diseases. Both powdery mildew and downy mildew were significantly less on the SAR elicitor treated plants. Preharvest treatment with SAR elicitors also reduced storage diseases of the harvested rockmelon fruit. The reduction in postharvest disease was similar whether plants were treated once, three weeks before harvest, or given four sprays during the growing season beginning at anthesis. A further postharvest dip with 500 ppm of guazatine gave substantial reduction of storage rots of melons. Enhanced activities of chitinase and peroxidase, two major PR-proteins, compared to the control, indicated induction of defence had occurred in the foliage and fruit as a result of SAR. Over the course of four field and one glasshouse experiments slight phytotoxicity was observed in plants frequently sprayed with INA or BTH, but no phytotoxicity was seen after a single spray during the late stages of fruit development. The combination of SAR elicitor treatment and use of a safe postharvest dip provided substantial control of storage rots of rockmelons. The best treatment for control of storage rots involved application of BTH (50 ppm) two weeks before harvest, combined with a hot iodine dip (55° C) of fruit, achieving equivalent or better disease control than use of guazatine fungicide dip.

Full textAbstract: This study aimed to determine the dynamics of plant growth, the pace of accumulation of nutrients in the culture and chemical modification of substrate composed of sand and peanut bark. The 'Fantasy' hybrid was cultivated in pots with substrate (mixture of sand and peanut bark in equal parts). The drip irrigation was performed with nutrient solution recommended for the hydroponic crops. The determining the dynamics of growth, the accumulation of nutrients and chemical changes in the substrate was done in six sampling dates. The harvest occurred at 78 days after transplantation being evaluate yield and fruit quality. According to the results, the net melon grown in substrates of sand and peanut bark, had continuous accumulation of dry matter until the harvest, being fruits the responsible for the largest percentage of accumulation in relation to other organs. The order of the nutrients was: N> Ca> K> P> Mg> S>B> Fe> Mn> Zn> Cu. The amount of potassium accumulated in plants was low, suggesting then verify the use of this nutrient in the nutrient solution. The substrate studied had low accumulation of nutrients by the end of the cycle. The amount of nutrients supplied by the nutrient solution was enough to plant productivity and ideal for the management of the substrate without providing its salinity. The sand and peanut bark substrate is excellent alternative for cultivation in substrate and use of waste agribusiness

O presente trabalho teve por objetivo avaliar o efeito de reguladores vegetais nas trocas gasosa durante o desenvolvimento da planta e na qualidade pós-colheita de frutos de melão rendilhado Galileu, armazenados em condições ambiente. A primeira etapa do experimento foi conduzida em estufa para cultivo protegido das plantas de melão, localizada na área experimental da Fazenda Experimental de São Manuel/UNESP, Botucatu, SP. A aplicação dos tratamentos foram realizadas no início da fase reprodutiva, 15 e 30 dias após a primeira aplicação. As medidas de trocas gasosas foram realizadas sempre no período das 8:00 às 11:00 horas da manhã, nas plantas controle e tratadas com os reguladores vegetais, no dia anterior e posterior à aplicação. Ci, A, gs e E foram feitas com um Infra Red Gas Analyser IRGA, modelo LI-6400 da LI-COR. As plantas receberam os tratamentos no campo (T1 controle, T2 GA3 (ácido giberélico) a 100 mg L-1, T3 IBA (ácido indolilbutírico) a 100 mg L-1, T4 cinetina a 100 mg L-1, T5 mistura de GA3 + IBA + cinetina a 5%), os frutos foram colhidos (51 dias após a primeira aplicação) e transportados ao Laboratório de Frutas e Hortaliças, pertencente ao Departamento de Gestão e Tecnologia Agroindustrial/UNESP, Botucatu, SP. Os frutos foram avaliados a cada 5 dias, durante 20 dias de armazenamento. As alterações pós-colheita foram detectadas por meio de análises de perda de massa fresca, firmeza, acidez titulável, pH, sólidos solúveis, relação SS/AT, açúcares totais, redutores e sacarose, atividade das enzimas peroxidase (POD), pectinametilesterase (PME) e poligalacturonase (PG). Os macronutrientes e micronutrientes foram analisados na colheita. O delineamento estatístico utilizado foi em blocos ao acaso com o controle e mais quatro tratamentos e quatro repetições que correspondem aos blocos. Nas condições em que o experimento...
This work's objective was to evaluate the effects of plant growth regulators on gas exchange during plant development and on post harvest quality of Galileu cantaloupes stored at conditions atmosphere. The first stage of the assay was conducted in a greenhouse (protected cultivation of cantaloupe plants), in the experimental area of São Manuel's Experimental Farm/UNESP, Botucatu, SP. The treatments were applied in the beginning of the reproductive stage, and 15 and 30 days after the first application. Gas exchange measurements were performed from 0800 to 1100 a.m, both in control plants and plants treated with plant growth regulators, on the previous and subsequent day from application. Ci, A, gs, and E were evaluated with a LI-COR model LI-6400 Infra Red Gas Analyzer - IRGA. The cantaloupe plants were treated in the field (T1 controls, T2 GA3 (gibberellic acid) 100 mg L-1, T3 IBA (indolebutyric acid) 100 mg L-1, T4- kinetin 100 mg L-1, T5- GA3 + IBA + kinetin mixture at 5%), and fruits were harvest (51 days after the first application) and transported to the Fruits and Vegetables Laboratory of Departamento de Gestão e Tecnologia Agroindustrial/UNESP, Botucatu, SP. The fruits were evaluated every 5 days during a 20-day storage period. Alterations in post harvest quality were detected through analyses comprising fresh weight loss, firmness, titratable acidity, pH, soluble solids, SS/TA ratio, total sugars, reduced sugars and sucrose, and activity of the enzymes peroxidase (POD), pectin methylesterase (PME), and polygalacturonase (PG). Macronutrients and micronutrients were analyzed at harvest time. The statistical design consisted of randomized blocks including a control, in addition to four treatments and four replicates that corresponded to blocks. Under the conditions in which the experiment was conducted, the results allow us to... (Complete abstract click electronic access below)
