Photo-Ecological Characteristics of Six Broad-Leaved Species Including Heptacodium miconioides in the Tiantai Mountains in Zhejiang Province

浙江天台山七子花等6种阔叶树光合生态特性


对分布在浙江天台山的七子花(Heptacodium miconioides)等6种主要阔叶树的光合生理生态特性进行了研究,结果表明:1)夏季6种植物光合日进程均为“双峰”型,有明显的光合“午休”现象。日均净光合速率月变化呈“单峰”型,8月是一年的高峰期。日均和5~11月平均净光合速率最高的是东南石栎(Lithocarpus harlandii),最低的是天台阔叶槭(Acer amplum var. tientaiense),七子花处于中下水平。2)相对常绿树种而言,七子花的光补偿点较高,光饱和点较低,对光

The photo-ecological characteristics of the six major broad-leaved species, including Heptacodium miconioides, in the Tiantai Mountains of Zhejiang Province were researched. In summer the diurnal variations of net photosynthetic rates (Pn) of the six spec
