| 摘 要： | 以１００ｍｇ／Ｌ ＡＮ喷洒蜡梅植株２次，能明显减轻ｐＨ为２．０模拟酸雨对蜡梅植株的伤害。本文认为，此与ＡＮ能提高叶绿素含量，增加光合速率与比叶重，抑制过氧化氢酶活性，减少光合产物损失，降低质膜透性，维持细胞液ｐＨ值稳定性等多重生理效应有关。

| Abstract: | AN reagent of 100mg/L was used to spray wintersweet two times.It reduced the damage effect of simulated acid rain at pH2.0 on wintersweet.The authors consider this effect is related to that AN reagent increases content of chlorophyll,raises photosynthetic rate and specific leaf weight,inhibits catalase activity,decreases the loss of photosynthates and cell membrane permeability of wintersweet,et al. |
