Efeitos da adubação com manipueira sobre o rendimento e qualidade dos frutos de tomate

The objective of this research was to evaluate the residue from cassava, known as manipueira, as an alternative for tomato (Lycopersicon esculentum) fertilization. This experiment was carried out in UNESP with the cultivar Rio Grande. The experimental design was a completely randomized blocks in a 3 × 3 factorial arrangement with five blocks. Treatments constituted the following: 1) witness; 2) 54 m3/ha of manipueira; 3) 108 m3/ha of manipueira; 4) half recommended mineral fertilization; 5) half recommended mineral fertilization + 54 m3/ha of manipueira; 6) half recommended mineral fertilization + 108 m3/ha of manipueira; 7) recommended mineral fertilization; 8) recommended mineral fertilization + 54 m3/ha of manipueira and 9) recommended mineral fertilization + 108 m3/ha of manipueira. Tomato yield, number of fruits per plant, fruit diameter and lenght, total soluble solids (TSS), total titratable acidity (TTA) and the ratio TSS/TTA were evaluated. The results obtained indicated that manipueira contributed significantly to yield and quality of pos-harvested tomato fruits.

Production and preservation of fresh-cut 'Tommy Atkins' mango chunks

During the 1999/00 and 2000/01 seasons, sliced 'Tommy Atkins' mangoes were packaged with three different types of polymeric films; polypropylene (PP) cups, low-density polyethylene (LPDE) bags or polyethylene terephthalate (PET) clamshell trays, and stored at 3°C for 2 weeks. The mango chunks were evaluated for flavor, appearance, colour, total soluble solids (TSS), total titratable acidity (TTA), ascorbic acid (AA) contents, O2 and CO 2 concentration in the packages, as well as respiration. Shelf life based on visual appearance was 14 days, with the products showing good appearance and agreeable aroma. The TTA content in chunks packaged in PP cups or PET trays were reduced during the storage, and with the color changing from light yellow to dark yellow. The chunks respiration in PP cups or LPDE bags were 64.6 and 87.9 mL CO2.kg-1.h-1, and in PP cups or PET trays were 45.86 and 43.92 mL CO2.kg-1.h -1, respectively for 1999/00 and 2000/01 seasons. The percentages of O2 and CO2 in the packages were stabilized after 2-4 hours, and the atmosphere had 11-17% and 1-10% of them. The microbiological content was lower than the allowed. No differences were observed between the seasons, and the best packages were the cups.

Postharvest conservation of 'Tommy Atkins' mango fruit influenced by gamma radiation, wax, hot water, and refrigeration

It was aimed to extend the postharvest conservation of 'Tommy Atkins' mango fruits harvested in break maturity stage. Fruits were submitted at the following treatments: hot water treatment (55°C for 5 minutes) and benomyl 1,000 mg.L-1; irradiation with 0,8 or 1,0 kGy; irradiation associated at carnaúba wax; and control. The fruits were stored at 10°C and 85 - 90%RH during 21 days, and then removed to ambient temperature (25,7±0,7°C and 87,1±2,2%RH). Through the storage time, the evolution of fresh weight, color, rottenness, total soluble solids (TSS), total titratable acidity (TTA), and TSS/TTA ratio were measured. 'Tommy Atkins' mango fruits can have shelf life notably increased, when they were submitted to hot water treatment (55°C for 5 minutes) or γ radiation (0,8 and 1,0 kGy), associated with carnaúba wax application, before cold storage. These treatments increased the fruit resistance at refrigerated storage, and improved shelflife after transferring to ambient temperature.
