摘　　要：以成年新次郎树为试材,进行了甜柿树体的光合、光照研究。结果表明,丰产稳产树较低产树和变产树在光合、光照方面有以下特点:树冠叶幕外层叶面积较大;叶幕中层光照状况较好;叶幕中层叶片净光合速率较高,在所有测定时期整株净光合速率均较高。Experiments in photosynthesis and light of persimmon leaf were conducted by using adult persimmon tree as tested material. The results indicated that comparing with low - yielding and alternativeyielding tree, the high and stable yielding tree had the following characters in photosynthesis and light of leaves ： bigger leaf area in the outer layer of the canopy, higher net photosynthetic rate and better light condition in the medium layer of the canopy, and higher net photosynthetic rate of the total tree leaf system at all testing stages.
