【摘要】 模拟酸雨对盆栽蚕豆 ( Vicai faba)植物生长的影响表明 ,它对出苗率影响不大 ,但当它的 p H为 2 .0时则对蚕豆初期的出苗速度有一定的促进作用。在苗出土后 ,酸雨的作用由促进转变为抑制 ,并随酸雨 p H值的降低而增大 ,致使株高、叶片生长和叶绿素含量减少 ,酸雨对叶片的伤害幼叶较老叶更容易更多还原

【Abstract】 The effects of simulated acid rain on bean(vicia faba)plant growth are studied, results show that the action of simulated acid rain on seedling rate is not obvious, but when its pH value is 2 0, it can increase bean early seedling speed in certain degree, After plant formation, comparing pH value in simulated acid rain decrease, its inhibition on the plant growth increases, this result in plant height, leaf growth and chlorophy content decrease, Yong leaves re more easily than old leaves in the injury of simulated acid rain更多还原
