Abstract
Studying floral biology is one of the important criteria for developing high yielding and quality passion fruit through breeding technique and management practices. An experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh farm to determine the flowering behavior, floral biology, fruit setting, yield and quality of passion fruits at varied flashes. Yellow passion fruits (Passiflora edulis Sims.) were grown in pits and their floral attributes were observed under different flashes. Comparison of floral attributes was made among the flashes. The results indicated that flower morphological attributes namely anther length and breadth, stigma diameter, ovary length and breadth were found better in third flash. Viability of pollen and their pollen germination on stigma, pollen tube growth inside the style were noticed as favorable during third and fourth flashes. The results concluded that third flash was the best in respect of floral attributes and floral biological parameters.
