Novel fungi from Kodaikanal, TamilNadu, India

Abstract :

The present study deals with the qualitative test for cytochemical localization of non-specific esterases on stigma surface of four endemic balsams viz., Impatiens elegans Beddome, I. floribunda Wight, I. maculata Wight and I. tangachee Wight. The style is short, solid, wet and non-papillate in all four candidate species. Stigma lobes are star shaped, when it shows maximum receptivity in all cases. In all the selected Impatiens species, stigma surface esterases could be detected as a thin layer on the stigma of flowers after the anther shedding. The esterases are present copiously on stigmatic lobes and slightly on the stigmatic head. The Impatiens species showed variation in stigma receptivity period and hence it did not support contemporary pollen germination and tube growth. The growth of pollen tube and stigma receptivity were influence by the presence of specific esterases on stigma surface.
