摘要：

The mature leaves of two clones of poplar were fumigated with 150 ppb of ozone for 5 h. In both clones a strong reduction in photosynthetic activity was observed, but the kind of the response appeared to be different. The resistant clone showed an effect at both stomatal and mesophyllic levels and this appeared to be a consequence of regulatory mechanisms more than effects of O-2 injury. A rapid recovery of photosynthetic ability was observed when the ozone was removed. The sensitive clone appeared not to be able to undergo this regulatory sequence, so the effects of ozone were stronger and not reversible. (C) 1998 Elsevier Science Ltd.
