SUMMARYThe effect of three centres of production, two times of lifting and two post-harvest treatments of apparently virus-free seed tubers on sprout development at planting was studied over two seasons. Sprout length and degree of development were determined mainly by the light and temperature conditions during storage. Under similar storage conditions tubers from the most southern region, lifted early and allowed to sprout from lifting produced longer sprouts than those from the more northerly regions, lifted late and sprouted from midwinter. At planting all tubers had sprouts longer than 2·5 cm. Desprouted tubers from the more southern regions had the highest number of sprouts at planting and tubers 'greened' immediately on lifting had the least.An index of sprout development at planting was defined. The conditions and duration of storage had most influence on the degree of development as measured by this index; sprouts were most developed on tubers sprouted over a long period and on those sprouted in a heated glasshouse. The effects of varying centres of production and times of lifting on sprout development at planting were small compared with those readily produced by varying the storage conditions.

The biological activity of benomyl and methylthiophanate residues in tomatoes and their processed products was examined. Fungicide residues were most active in concentrated pulp of tomatoes, less in pulp and the least in fresh fruits. The fungicide residues activity was very high after 90 days of storage of processed products. The pulp and concentrated pulp of tomatoes treated and stored for 14 days at 15°C, also contained very active fungicide residues. The translocation of benomyl from treated tomato skin into the tissue begun slowly. This process was faster in green or yellow fruits, but it was the fastest in small green fruits. The influence of storage conditions on the activity of fungicide residues depended on the storage length. The residues were the least active in fruits stored under low pressure of 38 mm Hg for 14 days, but this activity increased during the storage period and the residues were very active after 34 days of tomato storage.

The influence of storage conditions on the quality of tomato fruits was tested. The rate of ripening was established in normal air, where tomatoes ripen quickly, under controlled atmosphere where they ripen more slowly and under low pressure, where they ripen slowest. The influence of post-harvest benomyl or methylthiophanate treatment on tomato rot, ripening, and biological value were examined. Post-harvest tomato treatment did not reduce fruit rot. The color of fruits and the processed products depended on the fungicide treatment. Concentrated tomato pulp made of fruits treated with methylthiophanate was redder than the others. The fungicide treatment increased or decreased the level of some chemical substances in the fruits in dependence on the applied fungicide, storage conditions and the length of storage, e.g. tomatoes treated with benomyl and stored for 14 days contained the highest level of vitamin C under 0% CO<sub>2</sub>:3%O<sub>2</sub> and tomatoes treated with methylthiophanate contained the highest level of vitamin C under 38 mm Hg. Degradation of vitamin C in pulp was faster than in the concentrated pulp. Tomato pulp made of tomatoes treated with methylthiophanate contained the lowest level of vitamin C.

Abstract The objective of this study was to evaluate the post-harvest quality of bananas (Musa x paradisiaca L.) Prata-anã and Nanica after application of exogenous ethylene (C2H4) during maturation. Bananas of Prata-anã cultivar were harvested 18 weeks after the anthesis (WAA) and those of Nanica cultivar with 13 WAA. After harvest, the fruits were submitted to 0, 1, 2, 3, 4 and 5 applications of 15 mL of ethyl-5/m3 in refrigeration chambers at 15ºC and later stored at room temperature (24 to 28ºC) and refrigerated at 15°C for 10 days. Peel color, fresh weight loss, firmness, total soluble solids, total bark chlorophyll, total bark and pulp carotenoids were evaluated at 0, 3, 4, 7 and 10 days after harvest (DAH). The Assistat program was used in statistical analysis. Among the storage conditions, fruits kept under refrigeration had a longer shelf life. The Prata-anã cultivar was superior to Nanica, presenting maturation indexes ideal for transport and commercialization, evaluated for the interactions of storage temperature, ethylene (C2H4) applications and storage time. It was concluded that the banana Prata-anã requires 3 and Nanica 4 applications of ethyl, for the harvest with 18 and 13 weeks, respectively, in order to promote a fast and uniform maturation.
