湖南省油茶低改工程资助课题“油茶产量影响因素研究”的部分内容；

本校为第一机构

本文着重研究了普通油茶(Camellia oleifera Abel)霜降类型及其优良单株生殖器官的形态结构及其生殖过程,并对油茶的生殖生态开展了一个周期(578 d)的研究.结果表明,普通油茶由花芽分化到种子成熟共需500 d;花果相会和花粉管萌发快是油茶生殖的两个主要特点,油茶的生殖过程包括五个阶段;花期或花时不遇是影响油茶授粉乃至落花的重要原因,花期阴雨、低温是影响油茶授粉和落花的主要气候因素,水分是油脂形成期的主导因子.油茶优良单株的生殖结构比一般油茶单株表现四方面的优势.用油茶优良单株为繁殖材料,建立花期、花时、果熟期一致的油茶林分,是提高油茶单位面积产量的关键途径;提高集约经营度,...

Camellia oleifera descent types, reproductive organ shape construction and its process have been studied. The results show that: Camellia oleifera from flower bud to seed mature need 500 days, the reproductive process includes five periods and two characteristics: flowers meet with fruit and pollen tube germinates quickly; flower period or flower open time not meeting is a main factor that influent pollination and flower drop; Overcast and raining, low temperature are also main climate factors; Water is a main factor in the term of fat forming; The reproductive construction of the dominant tre...
