| 摘 要： | 通过喷淋试验,研究不同pH模拟酸雨对台湾桤木叶片K＋、Ca2＋、Mg2＋渗出量的影响。经过一定时间的酸雨胁迫,台湾桤木苗木叶片K＋、Ca2＋、Mg2＋渗出量随着pH值的减少而增加,呈现负相关效应。处理I-V的叶片K＋渗出量分别比对照（CK）升高34%、25.5%、17.4%,16.7%,11.4%;处理I-V的叶片Ca2＋渗出量分别比对照（CK）升高36%、25%、18%、5%、3%;处理I-V的叶片Mg2＋渗出量分别比对照（CK）升高58.3%、41.6%、37.5%、29.2%、22.1%。并且随着酸雨胁迫时间的延续,叶片K＋渗出量和Mg2＋渗出量的变化趋势均大致为先升高后下降,而Ca2＋渗出量则不断降低。

| Abstract: | The effect of leakage amount of K＋, Ca2＋, Mg2＋ in leaves of Alnus formosana with different pH of simulated acid rain was investigated by spraying experiments. After a certain period of acid rain stress time, the leakage amount of K＋, Ca2＋, Mg2＋ in leaves of A. formosana seedlings reduced with the increasing of pH value, showing a negative correlation effect. The leakage amount of K＋ in leaves of treatment I-V decreased by 34%, 25.5%, 17.4%, 16.7%,11.4% respectively, compared with the control （CK）;the leakage amount of Ca2＋ in leaves of treatment I-V decreased by 36%, 25%, 18%, 5%, 3% respectively, compared with the control （CK）; the leakage amount of I-V treatment of Mg2＋ in leaves were decreased by 58.3%, 41.6%, 37.5%, 29.2%, 22.1% respectively, compared with the control （CK）. The changes of leakage amount of K＋ and Mg2＋ in leaves generally increased firstly and decreased afterwards with the prolonging of stress time, but the leakage amount of Ca2＋ gradually reduced. |
