Changes in chemical composition during storage of squashes and pumpkins

Este trabalho objetivou avaliar a conservação pós-colheita de morangas (Curcubita maxima Duch.) e abóboras (Curcubita moschata Duch.) tendo como padrão o híbrido ‘Tetsukabuto’ Os teores de sólidos solúveis e beta-caroteno cresceram até o final do período de armazenamento, ocorrendo o inverso com o teor de amido. Os açúcares redutores e não-redutores tiveram aumentos até o 35º dia de armazenamento, e daí em diante decresceram. Os açúcares totais e relação açúcares/amido aumentaram até 56 dias, com uma redução aos 70 dias de armazenamento. O híbrido ‘ESAL 7511 x ESAL 7523’ apresentou composição química semelhante ao 'Tetsukabuto'.Changes in chemical composition were determined during storage of squashes (Curcubita maxima, Duch.) and pumpkins (Curcubita moschata, Duch.) for 70 days. The hybrid 'Tetsukabuto' was used as standard. During the storage period, total soluble solids and beta-carotene increased whereas starch content decreased; reducing sugars and non-reducing sugars increased up to 35 days and then decreased; total sugars and ratio total sugars/starch increased up to 56 days and then decreased at day 70. The hibrid 'ESAL 7511 x ESAL 7523' gave similar chemical composition to 'Tetsukabuto

ESTIMATIVAS DE PARÂMETROS GENÉTICOS E FENOTÍPICOS EM CEBOLA MÚLTIPLA

This work has objective estimates the heritability and the phenotypic correlations between characteristics of bulb and plant of lineages of multiple-onion half-sib families as subsidy for programs of improvement for the conditions northeast. One field experiment with radonmized complete blocks and with 14 half-sib families and three replications, were carried out. The greatest heritability coefficient was expressed by bulb number per plant. The high heritability obtained from the character number of bulbs for plant can compensate the low associations with the yield before and after cure, respectively, what it makes with that that characteristic can be used in the indirect selection for yield. The longitudinal diameter is a characteristic that can be used for indirect selection aiming at to increase the yield after cure of multiple onion. It is possible to obtain success with the selection for the traits number of bulbs for plant, height of the aerial part, longitudinal diameter, traversal diameter, format index, content of total soluble solids and productivity after the cure. The estimates of simple correlations evidence that is possible to obtain desirable recombinants individuals with high productivity and quality of bulbs

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set.
