Abstract
The pollen-pistil interaction involves the transfer of chemical signals from pollen to the stigma during the time of pollination. The structure of pollen grains and the stigmatic surface strongly supports the effective pollination. After the germination process the pollen tube travelled through the stylar tissue. The chemical substances in the stylar region direct the pollen tube for successful fertilization.
Investigations were carried on the structural anatomy and cytochemical staining particularly for presence of protein in the tissues of the stigma and style of Datura inoxia Mill. (Solanaceae). The stigma was found to be wet and contain surface proteins as revealed by the CBB stain. The style was long and solid with central core of transmitting tissue throughout the length of the pistil. The transmitting tissue is compact and oval shaped. The intercellular spaces through which the pollen tubes grow contain many proteinaceous substances. The present work indicated the location of proteins in the region of stigmatic surface and in the stylar tissue.
