简介：在酸土壤成长的植物可以承受两磷(P)缺乏和铝(艾尔)毒性。水耕法的实验被承担在幼苗生长，叶绿素和脯氨酸内容，抗氧化的反应和类脂化合物上估计单身者和艾尔毒性和低P应力的联合效果在艾尔忍耐不同的二米饭遗传型(Yongyou8和Xiushui132)的peroxidation。艾尔毒性和P缺乏两个都禁止了米饭幼苗生长。有毒的症状的发展被减少的叶绿素内容描绘，在根和叶子增加了脯氨酸和malondialdehyde内容，并且增加了在根的peroxidase和superoxidedismutase活动，但是在叶子减少了。应力条件在Yongyou8导致了更严重的生长抑制和氧化应力，并且Xiushui132显示出更高的公差到艾尔毒性和P缺乏。P缺乏加重了艾尔毒性种生长并且导致了更严重的类脂化合物peroxidation。
