Abstract

Abstract

Nymphoides indica (L.) O. Kuntze an emergent aquatic plant of Menyanthaceae, commonly called ‘floating hearts” is bisexual, hypogynous and distylous (Two types of style – long style and short style) with 4 – 8 sepals and petals. Stamens correspond to the number of petals. The present study deals with phenology, pollen biology and stigma receptivity of N. indica. The pollen grains are yellow, medium, monad, triangular, heteropolar, radially symmetric, parasyncolpate and prolate – spheroidal in shape. The viable pollen grains becomes pink or red in 1% aceto carmine, blue coloured in aniline blue lactophenol stain and brown coloured in IKI solution. Stigma receptivity was high in the post pollination period.

 

Keywords: Nymphoides indica, floating hearts, phenology, stigma receptivity, pollen viability
