| 摘 要： | 研究了模拟酸雨对荔枝、龙眼、柑橘等13种南方果树的叶片伤害、新梢增长率、细胞膜透性及叶片叶绿素含量的影响。结果表明,模拟酸雨抑制果树的生长,对叶片产生可见伤害,细胞膜透性增加,叶绿素含量降低;不同果树对酸雨的抗性也与酸雨的pH相关,芒果、枇杷、黄皮对酸雨抗性较强;猕猴桃、李、青梅、番石榴对酸雨最敏感;pH3.0～4.0是大多数南方果树产生显性伤害阈值,pH4.0可作为隐性伤害阈值。

| Abstract: | Resistance of 13 fruit crops (litchi, longan and species of citrus fruits) to acid rain was studied through observing and measuring the damaged degree of leaves, branch growth, cell membrane permeability and chlorophyll content. The results showed that under acid rain stress branch growth was inhibited, cell membrane permeability increased and chlorophyll content decreased. The resistance of fruit crops was related to the pH value of acid rain; Mangifera indica L., Eriobotrya japonica Lindl. and Clausena lansium (Lour) Skeels. were the highest resistant fruit crops to acid rain, Actinidia chinensis Planch., Prunus salicina Lindl., Prunus mume Sieb. & Zucc. and Psidium guajava L. were the most sensitive ones to acid rain. |
