Abstract
In this study,pollen adhesion,germination and pollen-tube penitration of sesame were characterized by paraffin sections and fluorescence microscope technique.A widely cultivated sesame variety,Zhongzhi No.14,was used as plant material.The results showed that there were no pollen grains adhered to the stigma 5min after pollination.Similarly,there were hardly any pollen grains adhered to the stigma 10min after pollination.However,large numbers of pollen grains began to germinate and the pollen tubes were growing out 30min after pollination.The pollen tube showed strong green fluorescence during germination and growing into transmitting tissue in style.Furthermore,the longest pollen tubes reached the bottom of style(the top of ovary) 2h after pollination.The average elongation rate of pollen tubes was estimated at 3.0mm per hour.At 4h after pollination,many pollen tubes had entered the ovary.Meanwhile,some pollen was still germinating or growing in pistil 24h after pollination.
