摘　　要：为选育出适合用作生物柴油的黄连木优良雌株,测定了37株黄连木初选优树的生长性状和结实性状等指标。结果表明,优树性状中胸径、冠幅、果穗粒数、含油率和结果枝率相互间相关系数都达到显著水平。采用单一指标和综合指标进行对比分析可确定初选优树1024、1027、1009、1007、1022、1012、1015、1020、1013为优良雌株;1011、1002和1004因其含油率低及产量低而被淘汰;另外其他单株可继续进行跟踪观测。The index of the growth traits and fruit character of 37 primary selected superior tree of Pistacia chinensis Bunge were determined in order to breed superior female tree of Pistacia chinensis Bunge which is used for biodiesel fuel.The experimental results showed that the mutual relations between diameter,crown diameter,grain number,oil content and fruit-shoot ratio in the superior tree were significant.The primary selection superior tree including 1024、1027、1009、1007、1022、1012、1015、1020、1013 were identified as superior female tree by the single indicator and overall indicator of comparative analyses.The 1011、1002、1004 were eliminated,since it has lower oil content and oil production.But other single-plants could be continuously observed.
