Pollen Feasibility of Passiflora Edulis Sims f. flavicarpa Degener

Abstract

The yellow passion fruit tis cultivated and commercialized throughout the Brazilian territory, it contributes to the generation of employment, and can be cultivated from micro to large producers. The Passifloraceae family is one of the most studied in breeding programs, aiming at the production of hybrids. The objective of the work was to identify the pollen viability of Passiflora edulis, using three dyes, being Lugol 2%, Alexander reactive 2% and blackcurrant juice. The data obtained were subjected to analysis of variance, followed by Tukey’s test to compare means at a significance level of 5%, using the R software. The results indicated a high rate of viable pollens, with no difference between the dyes used, since that the reactive dye Alexander was the one that best enable the identification of viable and non-viable pollens.
