Abstract:Synchronous flowering was observed in the clumps of Schizostachyum dullooa established with rhizomes from Arunachal Pradesh and planted in the Bambusetum of Kerala Forest Research Institute Field Research Centre (N 10o 26’ 31” E 76o 21’ 36.9”) at Veluppadam, Thrissur, Kerala, during August, 2010. Observations were recorded on floral morphology, opening of spikelets, pollination, pollen viability, pollen germination fertilization and post flowering behaviour. Inflorescence of S. dullooa is a large panicle and the spikelets were dichogamous, protogynous and open. Abundant pollen production was observed with high viability (96-98 %) and in vitro pollen germination. Although, bees visited the flowers and foraged anthers, they did not have any role in pollination. The mode of pollination was anemophily. Flowering was followed by abundant seed and seedling production and death of the culms.

Keywords:Schizostachyum dullooa, reproductive biology, seed production, pollen viability, post flowering behaviour
