    O objetivo deste trabalho foi caracterizar alterações químicas relacionadas à qualidade da manga Tommy Atkins, durante o desenvolvimento e maturação, nas condições de cultivo do Vale do São Francisco. A manga Tommy Atkins madura apresentou o máximo teor de sólidos solúveis totais (SST), porém os teores de vitamina C e de carotenóides totais da polpa foram inferiores aos dos frutos em estádio inicial de maturação. As mudanças na acidez total titulável e nos teores de SST e carotenóides totais da polpa foram indicativas da evolução da maturação

    The expansion of agriculture, coupled with the need for sustainable cropping, is one of the greatest challenges of the scientific community working on the generation of new cultivars adapted to abiotic stress conditions. The aim of this study was to evaluate the variability of popcorn lines as to responsiveness and efficiency in phosphorus use, as a first step towards the implementation of a breeding program interested in the practice of sustainable agriculture. Twenty-five popcorn lines were evaluated in two locations with different phosphorus levels in the soil, using a randomized block design. The following traits were measured: plant height, ear height, female flowering date, male flowering date, male-female flowering interval, ear diameter, ear length, 100-grain weight, grain yield, popping expansion, and expanded popcorn volume per hectare. A combined analysis of variance and test of means were performed, and the lines were classified as to their phosphorus use efficiency, according to their production performance in the different environments. The genetic diversity between the lines was estimated by Tocher?s and UPGMA clustering methods, using generalized Mahalanobis distance. Lines L59, P7, P2, P3, P4, P8, P10, P9, L66, L70, L69, and P5 were efficient and responsive, whereas lines L75, L80, L61, L77, L63, L65, P1, L54, L53, L88, and L71 were inefficient and nonresponsive. Genetic variability was greater in the environments with low phosphorus in the soil, suggesting that the selection pressure exerted in the stressing environment is a decisive factor to obtain a higher expression of variability

    Comparison between visitation of honey bees (Apis mellifera) on male and hermaphrodite flowers of yellow melon (Cucumis melo) using different number of hives: 2. one and both floral types analysis

    Get PDF
    Yellow melon (Cucumis melo) is an important fruit for production and exportation in Brazilian fruit culture. Honey bees (Apis mellifera) play an essential role on this being responsible for pollination and, consequently, improving production and better quality fruits. The objective of this work was to compare the bees? visitation on male and hermaphrodite flowers in a crop area using different number of hives
