茶树植物生殖能力的强弱,除直接表现在花、果与种子量上,还表现于子室的能育程度上。但这些与不同的种群或品种间的演化程度、遗传特性或雌雄两性结构形式等似有密切关系。据我们已研究结果表明:西南及华南区系中,许多原始或较原始的乔木大叶种,其生殖能力普遍低于东南或中北部灌木中、小叶种。 Tea plants reproductive capacity of the strength, in addition to direct performance in flowers, fruits and seeds, but also manifested in the sub-room on the level of fertility. However, these are closely related to the evolution, genetic characteristics or the structure of both sexes of different populations or varieties. According to the results we have shown, in the southwestern and southern China fauna, many original or pristine arborvitae species generally have lower reproductive capacity than those in southeastern or central-northern shrubs.
