以辣椒杂交种甘科5号的双亲为试验材料，研究了花蕾大小与授粉时间对辣椒座果率、结实率及种子质量的影响。结果表明，不同处理的座果率、单果种子数量和质量存在显著或极显著差异。大蕾去雄次日上午授粉处理和大蕾去雄即授粉处理的座果率比小蕾去雄即授粉处理分别提高了21.5和14.2百分点，大蕾去雄次日上午授粉处理和大蕾去雄即授粉处理的单果种子数量和质量均比小蕾去雄即授粉处理有较大提高。不同处理的种子发芽率和发芽势差异不显著。

Pepper hybrid cultivar Ganke 5's parents are used as the experimental material， the effects of bud size and pollination time on fruit setting rate， seed setting rate and seed quality of pepper are studied. The test results show that the different fruit setting rate rate， seed quantity and quality have significant or extremely significant differences. The fruit setting rate of pollination in next morning after emasculation of big bud treatments and Immediate pollination after emasculation of big bud treatments than Immediate pollination after emasculation of the small bud treatments are increased by 21.5 and 14.2 percentage points. The seed quantity and quality of pollination in next morning after emasculation of big bud treatments and Immediate pollination after emasculation of big bud treatments than Immediate pollination after emasculation of the small bud treatments have greatly improved different treatments， the seed germination rate and germination potential of difference treatments is not significant.
