一、引言在树木的生态生理研究中,用树木离体部分研究光合作用率的例子很多,这种方法是可行的,因为它能粗略地算出树木大体上的光合能力。关于受伤树枝或叶柄影响光合能力的报导只有几篇,例如:G_(LARK)(1954),N_(EGISI)与S_(ATOO)(1955)报导了用乔木材料进行研究的结果;B_(ARUA)(1960)和I_(TO)(1965)报导了用灌木材料进行研究结果;另外R_(ICHARDSON)(1957)、S_(AKAGAMI)与D_(OI)(1963)和N_(AKAMURA)(1970)在乔木材料方面也有部分报导。
I. INTRODUCTION There are many examples of tree photosynthesis rate studies in the ecological and physiological research of trees. This method is feasible because it can roughly calculate the tree’s general photosynthetic capacity. There are only a few reports about the effects of injured branches or petioles on photosynthetic capacity. For example, G_ (LARK) (1954), N_ (EGISI) and S_ (ATOO) (1955) reported the results of arbor wood research. (1957), S AKAGAMI, D OI (1963) and AKAMURA (1970) were reported in the 1960s and I TOEs (1965) Part of the tree material is also reported.
