| 摘 要： | 试验研究了耐弱光性不同的桃品种在遮荫下光合特性的变化.结果表明,遮荫下,植株通过降低光补偿点、夜间呼吸速率,增大气孔导度、蒸腾速率,增加叶绿素b相对含量等生理机制适应遮荫环境.研究同时表明,植株通过光合调节适应遮荫的能力在30遮荫下比70遮荫表现明显;不同品种的适应能力具有很大差异.

| Abstract: | Photosynthetic characteristics under different shading treatments were investigated in different peach culti-vars with different low light-tolerance. The result showed that the trees could adapt to stress by decreasing light compensation point and night respiration rate, and increassing Gs. ,Tr. , relative Chl. b content. The results also showed that the adjustment ability of trees 30% shading was more obvious than that under 70% shading. Significant differences of adaptability were found among different varieties. |
