Pepper (Capsicum annuum L.) is one of the most important vegetable crops. Although it has some tolerance to the ambient environment, its pollen viability and seed set are greatly affected by it. High temperature together with high light intensity which often happens in summer and early autumn, and low temperature together with low light intensity which occurs in early spring and late autumn always lead to flower bud drop, flower drop, abscission of fruits and so on.
辣椒是一种重要的蔬菜作物，一般认为它喜温且能耐一定程度的弱光，但其开花及结实受外界环境条件尤其是受光、温条件的影响较大，夏秋季的高温强光和早春、晚秋的低温弱光天气均能引起辣椒落蕾、落花、落果，严重影响产量，是辣椒生产中迫切需要解决的问题。
The development of anther and ovule followed the finish of the flower organ initiation. Pollen mother cells and well developed microsporagium wall occurred when the diameter of the bud reached about 3.0 mm, and the archesporial cell which played the role of megaspore mother cell formed in ovule when the diameter of the bud reached about 3.5 mm.

The results suggest: the three culturalss pollen germination percentage were more than 60% 4 h after cultured in liquid culture medium composed 10% sucrose, 24℃; Florescence most concentrated April third-tenth (2003 For Zaomeisu and Qiyuesu, their anthotaxy and flower self setting fruit percentage were more than 90%, except for China pear 1, anthotaxy self setting fruit percentage was 48.3%, flower self setting fruit percentage was 33.1%; Their cross-compatibility was higher, anthotaxy and flower self setting fruit percentage almost reached 100%, the lowest also reached 94.9%, but last self-compatible gathering fruit percentage was lower comparatively and fruit average seed numbers were lower, while cross-compatible gathering fruit percentage and fruit average seed numbers were closed to that of nature pollination.
对梨品种亲缘关系很近的早美酥、中梨1号、七月酥等进行的花粉发芽率、花期调查、自交亲和性、异交亲和性调查的结果表明：三者的花粉在10%的蔗糖液培养基上，24℃左右培养4h后花粉发芽率均能达到60%以上；三者的花期大都集中在4月3日-10日(2003年)；早美酥、中梨1号、七月酥的自花授粉坐果率，除中梨1号的花序自花授粉座果率为48.3%，花朵自交座果率为33.1%外，早美酥、七月酥的花序自交座果率和花朵自自花授粉座果率均达到90%以上；它们的异花授粉坐果率更高，在本试验中花序坐果率和花朵坐果率都可达到94%以上，但最终采果率自花授粉的相对低一些，果实平均种子数也低，异花授粉的最终采果率和果实平均种子数与自然授粉条件下的近似。
