摘　　要：以杏树雌蕊败育率不同的5个品种为材料,对其在6月份、8月份和9月份的光合速率进行了测定。结果表明,不同杏树品种的光合速率差异不显著,说明光合速率与雌蕊败育率之间没有直接相关关系;虽然光合速率与败育率无相关关系,但品种的光辐射利用能力与雌蕊败育有明显的关系,光辐射利用能力强的品种其雌蕊败育率低。杏树不同发育时期的光合速率存在极显著差异,6月份光合速率明显高于8月和9月。Determination on the photosynthetic rate of five apricot varieties with different pistil sterile percentage in June,August and September showed that the Pn of different varieties were not significantly different when Duncan's new multiple range test was done.The pistil sterile percentage was significantly correlated with the utilization ability of the light radiation.That is to say,the variety with lower pistil sterile percentage had higher utilization ability of the light radiation. But the Pn of different periods were significantly different,the Pn of June was markedly higher than,the Pn of August and September
