Abstract

A study on flower biology of black pepper (Piper nigrum) was carried out to provide important understanding in flower biology which is vital to breeding and hybridization studies in Vietnam. Three varieties namely Vinh Linh, Phu Quoc and SRLK have been used for this study. The results showed that it takes about 242 days to 270 days from spike appearance to fruit ripening. The longest period is fruit development and fruit maturity. Anther dehiscence of Vinh Linh and Phu Quoc occurs at around 7:00 pm to 8:00 pm. However, SRLK is earlier at 4:00 pm to 5:00 pm. Sigma receptivity happens 1.8 days to 2.8 days after anther dehiscence. Stigma remains receptive from 4 days to 6 days and up to 10 days.
