摘　　要：利用超氧化物歧化酶(SOD)活性增强物质,研究了人工调控下东北常见的藜和碱地肤2种盐生植物和豚草、三裂叶豚草2种非盐生植物对混合盐胁迫的形态响应特点,同时探讨了SOD活性增强物质对植物抗盐性的影响。结果表明:盐生植物和非盐生植物在高浓度混合盐胁迫时,显著影响了植株高度和叶片的长度,非盐生植物相比盐生植物受到的影响相对较重,SOD活性增强物质能够颉颃混合盐胁迫对植物的危害,盐生植物相对非盐生植物更为敏感。这可能和盐生植物SOD活性往往较高,致使得植物盐害得到有效修复有关。Using SOD activity-enhancing substances Chenopodium album L. ,the morphological response characteristics of Kochia sieversiana （Pallas） C. A. Mey. and Ambrosia artemisiifblia L. ,Ambrosia trifida L. under mixed .salt stress under artificial conditions were studied, at the same time, the effect of SOD activity substance on plant salt resistance were investivated. The results showed that, the halophytes and non halophycs at high concentration of mixed salt stress conditions,plant height and leaf length were inhibited obviously non halophytes was injured more seriously than halopbytes, the increase of SOD activity substances on halophyte and nomhalophytes growth inhibition had significantly improved,and tile effect was more remarkable in halophytes. The halophyte often had higher SOD activity makes the plant salt effectively repair also were concluded.
