| Abstract Passiflora cincinnata is a species of wild passion fruit whose fruit has potential for use by the food industry. In this context, an anatomical study of the pericarp may help in understanding the changes which occur during the postharvest period. The objective of this work was to anatomically characterize the P. cincinnata pericarp, focusing on the structural changes which occur during refrigerated storage. The selected fruits were kept in net-like packaging at 5°C and evaluated every 15 days for a period of 90 days. Pericarp samples were hand cut on these dates for structural description and to detect starch, phenolic compounds, alkaloids, polysaccharides, proteins, lipids and lignin through histochemical tests. Other samples were analyzed by... |

| The use of Passiflora species for ornamental purposes has been recently developed, but little is known about pollen viability and the potential for crossing different species. The objective of this study was to evaluate the pollen viability of six Passiflora species collected from different physiological stages of development through in vitro germination and histochemical analysis using dyes. The pollen was collected in three stages (pre-anthesis, anthesis and post-anthesis). Three compositions of culture medium were used to evaluate the in vitro germination, and two dyes (2,3,5-triphenyltetrazolium chloride, or TTC, and Lugol's solution) were used for the histochemical analysis. The culture medium containing 0.03% Ca(NO3) 4H2O, 0.02% of Mg(SO4 ).7H2O,... |

| ABSTRACT: The aim of this research was to determine the sample size needed to estimate the average of wild passion fruit ( Passiflora caerulea ) traits. It was collected randomly, 133, 99 and 133 fruit of wild passion fruit in 30, 21 and 29 plants, located respectively, in the cities of São Borja, Itaqui and Uruguaiana, on the west border of Rio Grande do Sul, Brazil, totaling 365 fruits harvested in 80 plants. In each fruit were measured ten traits: width, length, fruit, skin, and pulp weight, pulp yield, luminosity and tone of skin and pulp. Then, central tendency, dispersion and distribution measures were calculated and the normality of the data checked. After, it was determined the sample size needed to estimate the average for each character, assuming... |
