| 摘 要： | 研究了３处生平生平茬香椿的光合特性。结果表明，香椿初展叶光合速率很低，约２０ｄ内增强，此后基本稳定，６０ｄ后又迅速降低。７月份单叶光合速率日变化为双峰曲线，有明显的光合“午休”现象。由于受叶龄及环境条件等影响，不同季节光合速率表现为生长前期和后期较低，中期较高。

| Abstract: | Photosynthesis of Chinese toon Toona sinensis (A.Juss.)Roem. at different growth stages,different leaf ages and the daily photosynthetic changes,as well as the influences of CO 2 concentration,light intensity and PP 333 treatment on photosynthesis were studied.The result showed that the hightest photosynhtetic rates were observed at plant rapid growing stage,and at leaf age of 20-60 days.The daily photosynthetic rates varied with a double peak curve,reaching the first peak at about 9:00 and the second peak at about 15:00.When applyed with PP 333 ,the height of Chinese toon was dwarted but its photosynthetic rate was slightly increased. |
