Aspects of Pollination and Floral Biology of Lablab Beans (Lablab perpureus L. Sweet)

Abstract

Different aspects of pollination and related floral biology of Lablab beans were studied at the Institute of Postradguate Studies in Agriculture, Salna, Gazipur, Bangladesh, Anthers and stigma of flower buds remained at close proximity to each other at their optimum maturity. The pollens reached complete maturity and stigma became fully receptive when the flower buds had their standard-base splitted. Healthy pollens could be obtained from the flower buds with their standard-base splitted but before anthesis. Successful emasculation and pollination could be done any time of the day with forenoon emasculation showing a slightly better result than afternoon emasculation. Equal success in crosses were obtained when pollination was done on the same day or on the following day of emasculation with one exception. Bagging after emasculation and pollination gave better results than without bagging.
