| 摘 要： | 用１０ｍｇ／Ｌ，２５ｍｇ／Ｌ和５０ｍｇ／Ｌ的ＰＰ＿（３３３）处理草莓，可降低由渗透胁迫所引起的草莓叶片相对含水量（ＲＷＣ）的降低程度，减缓质膜相对透性值和过氧化物酶（ＰＯＤ）活性的上升幅度，降低超氧歧化酶（ＳＯＤ）活性和丙二醛（ＭＤＡ）含量，延缓草莓叶片可溶性蛋白质和叶绿素含量的下降，其中以２５ｍｇ／Ｌ浓度的ＰＰ＿（３３３）处理对提高草莓抗旱效果最好。

| Abstract: | Under water stress,the relative plasmalemma permeability in leaves of strawberry(Fragariaananassa Duch) was reduced by PP_(333) at concentration of 10mg/L, 25mg/L and 50mg/L.The relative watercontent(RWC) in leaves were higher than that of contral. It was found that PP_(333) increased POD activity anddecreased the malondialdehyde(MDA) content and the superoxide dismutase(SOD) activity,it retarded the de-creased the content of chlorophyll and soluble protein in leaves of strawberry grown under water stress,The effectof drought-resistence with 25mg/LPP_(333) has been shown better. |
