Abstract— The present paper deals with the stigma receptivity in terms of in vivo pollen germination of Grewia asiatica L. (Tiliaceae), an economically fruit yielding plant, with a view to find out the stigma receptive period and correlation of stigma receptivity with the activity of esterase and peroxidase on stigmatic surface in order to provide information about reproduction as a basis for fertilization and plant breeding programme. Flowers open at 7.00 hrs to 8.30 hrs. Anther dehisces by longitudinal slits just before flower opening. The non-specific esterase and peroxidase are present densely all over the stigmatic head. Stigma showed maximum receptivity (91.5%) with mean pollen tube of 338µm after 3 hrs of anthesis. Conspicuous presence of esterase and peroxidase was observed during higher receptive period. Prominent presence of peroxidase enzyme was also observed after 3hrs of flower opening (45 oxygen bubbles/minute by using hydrogen peroxide) during maximum receptive period of stigma.
Keywords— Stigma receptivity, esterase, peroxidise activity, Grewia asiatica L.
