摘　　要：以3种攀援植物为材料,测定其阳生、阴生叶片光反应曲线、比叶重、叶绿素荧光在中午自然条件下及人工强光照下的变化．结果表明:3种植物光抑制敏感性不同,阴生叶具有更高的光抑制敏感性;低比叶重虽然提高叶片对低光照的适应,但成为提高叶片对光抑制敏感性的一个重要因素．Light response curves of photosynthesis, special leaf fresh weight, chlorophyll fluorescence at noon in field and under high light were determined in sun and shade leaves of 3 species of climbing plants. The results indicated that the susceptibility to photoinhibition of a species plants is different, and it＇s higher in shade leaves than that in sun leaves. Although decrease of SLFW benefits leaves from low light adaptation, it also becomes a major factor to make leaves sensitive to photoinhibition.
