摘  要:
以2个8年生攸县油茶优良无性系为试材,研究了自花授粉、异花授粉、去雄不授粉及自然授粉四种授粉方式对其坐果率、落果动态及果实生长动态的影响。结果表明,攸县油茶不同授粉方式的坐果率有差异,坐果率从高到低的顺序依次为:异花授粉>自然授粉>自花授粉>去雄不授粉。四种授粉处理的落果高峰期均出现在授粉后两个月内,其中以去雄不授粉落果率最高,异交落果率最低。果实横、纵径生长规律均呈现单"S"曲线,授粉4个月以后,异花授粉处理果实的横、纵径均大于其他3个处理。

摘  要:
Camellia yubsienensis Hu. is the Theaceae Camellia plants. different pollination of C. yuhsienensis Hu. have different influence on fruit-bearing. When fruits were ripe, fruit setting rate high to low order is: cross-pollination > natural pollination > selfpollination > no-pollination. Fruit drop peak oppears in the first two months after pollination. Fruit transverse and longitudinal diameter growth curve is single "S" type. When fruits were ripe, cross-pollination fruit transverse diameter is longer than natural pollination, both of which is also longer than self-pollination fruit transverse diameter.
