摘要

摘要: 以橡胶树(Hevea brasiliensis Muell.Arg.)RRIM600、GT1、RRII105、IAN873、RRIM712、PB217等6个品种为对象,对不同品种橡胶树雌花分布和座果位置进行了观察和统计。结果表明:不同橡胶树品种间,圆锥花序上雌花的个数、雌花在花序上的位置分布和结果侧枝上的花序数存在极显著差异。雌花和果实在圆锥花序上的分布规律相似,主要分布在圆锥花序的顶端和下部;结果花序主要分布在结果侧枝的下部,圆锥花序距离树干越远,则花序结果的几率越小。因此,在橡胶树杂交育种时,可以只对相关品种座果率高的结果侧枝相应位置上的花序及花序上相应的雌花进行授粉,而摘掉其余座果率低的花序和雌花,从而提高杂交育种效率和效果。

Abstract: The disciplines of pistillate flower distribution and fruit-set location of six cultivars were investigated in Hevea brasiliensis. Results showed that there were significant differences in the number of pistillate flowers, locations of pistillate flowers on panicles and number of panicles in fruit-set branches among different cultivars. Similar to the distribution of fruits on panicles, pistillate flowers were distributed on the top or lower positions of panicles. Pistillate flowers that produced fruits grew mainly on the lower positions of the fruit-set branches. The pro-bability of fruit-set decreased with distance between panicles and trunk increasing. Thus, based on the disciplines of pistillate flower distribution, fruit-set panicles and fruit, the efficiency of crossbreeding could be improved by pollinating panicles on the fruit-set branches with higher fruit-set rates and synchronously thinning pistillate flowers with lower fruit-set rates.
