Studies on Floral Biology of Different Carica Species

M.A.K. Azad and M.G. Rabbani    

Abstract: An investigation was carried out to study the floral biology of different Carica species. Early flowering was occurred in C. cauliflora both male and female flowers after transplanting of the seedlings and male flower emerged earlier compared to female flower of different Carica species. The tallest rachis of male inflorescence was obtained from C. papaya cv. Shahi. The male flower buds of C. papaya cv. Ranchi took the highest time from initiation to dehiscence and the maximum time was required from initiation to receptivity in C. papaya cv. Shahi. The anthers dehiscence of all species were increased with the increasing the temperature up to 12 p.m. during the study. The maximum female flower opening was observed in C. cauliflora at 8-9 a.m. The opening of flowers Shahi and Ranchi were gradually increased from 6 to 8 a.m. and declined after 8 to 11 a.m. The cent percent fruit set was recorded in C. cauliflora on the day of anthesis and the fruit sets were decreased with increasing the anthesis period up to 5 days after anthesis. No fruit set was found at 6 days after anthesis.
