Floral biology of Anisomeles malabarica R.Br.
Journal Title: Bioscience Discovery - Year 2017, Vol 8, Issue 1
Abstract
The floral biology of Anisomeles malabarica R.Br. was revealed by the study of floral morphology, anthesis, anther dehiscence, Pollen numbers, Pollen load, type of nectar, breeding behaviour by autogamy, geitonogamy and xenogamy was tested through controlled pollination, floral visitors and Bud drop. lntensive flowering period was noticed between February and April. Life span of flowers is approximately 15 days and anthesis take place between 1.50 a.m. to 2.05 a.m. The nectar secretion is maximum at 8-10 am at time of flowering and concentrated by fructose, sucrose, and glucose respectively. Approximately 1250 pollen grains per anther were recorded. Pollen viability was about 98% and stigmatic pollen loads was maximum at 8-10 am. The floral forages comprising butterflies like Danaus genutia, Belenois aurota, Papilio demoleus and insects such as Xylocopa sp. visited intensively during 8-10am. There is a correlation between nectar secretions, forages visitation and stigmatic load have been revealed. In controlled pollination treatments Xenogamy resulted 75% of flowers was fruit set. By this study the life cycle of Anisomeles malabarica R.Br. was documented.
