| Abstract: The objective of this work was to evaluate the effects of CaO-based particle film on the physiological parameters of cowpea (Vigna unguiculata) subjected to water restriction. Plants were subjected to two levels of soil moisture and three concentrations of the film, as follows: control, without film + 100% crop evapotranspiration (ETc); without film + 50% ETc; 5% CaO + 50% ETc; 10% CaO + 50% ETc; 5% CaO + 100% ETc; and 10% CaO + 100% ETc. Plants treated with 50% ETc remained stable with the application of 10% CaO particle film and showed high photosynthetic assimilation of CO2 (32 μmol m-2 s-1), moderate transpiration (5.6 mmol m-2 s-1), maintenance of chlorophyll content, and greater intrinsic water-use efficiency (IWUE, 226.65 μmol mol-1) and... |

| The physical-chemical quality changes in mangaba fruit were studied. The fruit which attained full development at half-ripe stage were harvested and initially stored at 6, 8, 10 and 12±1ºC for four days. After this period, the fruit were transferred to an acclimatized room (24±2ºC) and maintained for five days. For control purposes, recently harvested fruit were stored directly in an acclimatized room (24±2ºC) for six days. After the transfer and storage at 24ºC, fruit were analyzed daily for their vitamin-C, soluble solids (ºBrix), titratable acidity, pH and firmness contents. In fruit directly stored at 24ºC, there was a sharp fall in vitamin C and acid contents. The fruit firmness decrease, after four days of storage, and they turned totally ripe. The... |

| Conduziu-se o presente trabalho com o objetivo de caracterizar física e quimicamente os frutos da mangaba quando estão "de caída" ou "de vez" e estudar o efeito de diferentes temperaturas de armazenamento sobre a conservação pós-colheita desse fruto. Os frutos foram selecionados e armazenados em câmaras frias nas temperaturas de 6, 18 e 25 ± 2ºC. Durante o período de armazenamento, foram retiradas amostras a cada 1, 3, 5, 7 e 9 dias, para determinações dos teores de vitamina C, pH, acidez titulável e sólidos solúveis (ºBrix), atividade de água, condutividade, resistividade e difusividade. Verificou-se que mangabas de caída apresentaram teores de vitamina C e sólidos solúveis superiores aos frutos "de vez". O armazenamento a 6ºC foi eficiente na manutenção... |
