Germination of Capsicum annuum cv. Bang Lane Pan Lakpollen collected from dehiscent and non-dehiscent anthers in a culture medium containing 25 percent sucrose, 100 ppm H3BO3, 300 ppm Ca(NO3)2. 4H2O, 200 ppm MgSO4. 7H2O 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 percentages of pollen grains from dehiscent and nondehiscent 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, germination percentage of pollen was increased in proportion to sucrose concentration, attaining maximum level at 25 percent.
