摘　　要：以盆栽珠美海棠实生苗为试材,研究干旱胁迫对其生理生化特性的影响。结果表明:随着干旱胁迫时间的延长,珠美海棠实生苗叶片的细胞膜相对透性、可溶性糖含量及过氧化氢酶(CAT)活性呈现不断升高的趋势;丙二醛(MDA)含量随着土壤含水量的降低,先逐渐升高,后基本维持在一定范围内。The Fragaia ananassa Duchesne seedlings were used as experimental material to study the effect of drought stress on the physiological indexes.The results showed that with the prolong of drought stress,the cell membrance relative permeability,the soluble sugar content and the activity of CAT increased gradually.MDA content increased first and kept in a range of basic maintenance.
