摘    要:以对酸雨胁迫伤害敏感程度不同的桃树(Prunus persica)、蜡梅(Chimonanthus praecox)和木犀(Osmanthus fragrana)3种典型木本植物为试材,研究了不同pH值的模拟酸雨对3种木本植物叶片叶绿素含量,细胞质膜透性(L%),脯氨酸(Pro)及丙二醛(MDA)含量的影响,以及光、暗条件对酸雨胁迫伤害的作用。结果表明,在酸雨胁迫下,抗性植物水犀的4项生理生化指标的变幅最小,其次是蜡梅,敏感植物桃树的4项生理生化指标的变幅最高,而光、暗处理对酸雨胁迫下3种木本植物叶片叶绿素含量影响不明显。

关 键 词:木本植物  酸雨  胁迫效应

Abstract:Osmanthus fragrana ,Chimonanthus praecox and Prunus persica were used as materials to investigate the effect of simulant acid rain on chlorophyll (Chl) content, cell membrane permeability(L%),the content of proline (Pro) and malondialdehyde (MDA) in three woody plants with different resistance, and effects of the light and dark conditions on acid rain injury. The results showed that the change degree of four kinds of physiological and biochemical indexes for these woody plants was as sequence: Osmanthus fragrana >Chimonanthus praecox >Prunus persica . The change of chlorophyll content in these woody plants was not obviously when acid rain stress was influenced by the light and dark.
Keywords:woody plant  simulant acid rain  stress effect
