| 摘 要： | 以具有亲缘关系的橡胶树(Hevea brasiliensis Muell. Arg.)热研88-13、热试47、热试62为研究对象，对不同品系橡胶树开花侧枝上的花序和花序上的一级花序、雌花、一级雌花、二级雌花的数量和位置分布进行了调查和统计分析。结果表明：不同品系橡胶树间开花侧枝上花序、一级花序、雌花、一级雌花、二级雌花的数量和位置分布差异显著，不同品系橡胶树间花序上雌花、一级雌花和二级雌花的数量和位置分布差异显著；橡胶树开花侧枝上的花序数、雌花数、一级雌花数、二级雌花数之间相关性显著，花序上的雌花数，一级雌花数和二级雌花数之间相关性显著。可以将开花侧枝上的花序数和/或花序上的雌花数作为品种识别的指标之一，将花序上的一级花序数、一级雌花数和二级雌花数作为品种识别的辅助指标。

| Abstract: | The structural features of inflorescence of three strains were investigated in Hevea brasiliensis. Results showed that there were significant difference in the number and locations of inflorescence, first class of inflorescence branch, pistillate flower, first class of pistillate flower, second class of pistillate flower in flowering branches and the number and locations of pistillate flower, first class of pistillate flower, second class of pistillate flower in panicles among different strains. whereas, there were significant correlation between the number of inflorescence, first class of inflorescence branch, pistillate flower, first class of pistillate flower, second class of pistillate flower in flowering branches and the number of pistillate flower, first class of pistillate flower, second class of pistillate flower in panicles. Thus, based on the differcence of inflorescence traits, the number of inflorescence in flowering branches and the number of pistillate flower in panicles can be the main indicators of a species identified by inflorescence, while the number of first class of inflorescence branch, first class of pistillate flower, second class of pistillate flower as the secondary indicators. |
