Effects of Light and Sucrose on Pollen Germination of Capsicum annuum cvs. Bang Lnae Pan Lak and Prik Chee Pha Bangkhen

Abstract

The germination of Capsicum annuum cv. Bang Land Lak pollen collected from dehiscent and non-dehiscent anthers in a culture medium containing 25% sucrose, 100 ppm H₃BO₃ 300 ppm Ca(NO₃)₂4H₂O, 200 ppm MgSO₄7H₂O and 100 ppm KNO₃ was studied. The result indicated pollen grains derived from both dehiscent and non-dehiscent anthers germinated in dark condition better than in cool light. The germination percentage of pollen grains from dehiscent and non-dehiscent anthers were 2.87 and 7.71 in dark and 0.22 and 0.49 in cool light condition, respectively. Moreover, for Capsicum annuum cv. Prik Chee Pha Bangkhen, it was found that germination percentage of pollen was increased in proportion to sucrose concentration, attaining maximum level at 25%.
