摘要
1990～1991年在北京中国林业科学研究院苗圃,以一年生美洲黑杨为试材,观测了人工摘叶以后引起的光合作用速率、叶片气孔导度、气孔阻力、主茎伸长生长和叶面积增长速率等生命过程的变化规律。研究证明了超越补偿作用的存在,以及在苗木的不同生长时期、不同摘叶量、摘叶后持续的时间内,超越补偿作用的特点。
During 1990~1991, in the nursery of the Chinese Academy of Forestry, leaf-plucking experiment of one-year-old Populus deltoides was conducted. The changing law of photosynthesis rate, stomatal conductance, stomatal resistance, main stem height growth rate and enlarging rate of leal area were observed, which proved the existance of over-compansation effect and expounded the characteristics of over-compensation effect in different growth stages, different leaf-plucking amount and different duration after leaf plucking.
