【摘要】 比较耐盐性不同的近等基因系小麦在盐胁迫 (1%NaCl)条件下 ,其超氧化物歧化酶 (SOD)活性、丙二醛 (MDA)含量以及叶片质膜透性这几个生理指标的变化 ,结果表明 ,盐胁迫条件下 ,耐盐性强的RH870 6 - 49材料SOD活性显著低于耐盐性差的H870 6 - 34,丙二醛 (MDA)含量以及叶片质膜透性也显著低于耐盐性差的H870 6 - 34更多还原

【Abstract】 Near isogenic lines wheat with different salt tolerance were compared for their SOD activities,malondialdehyde(MDA) contents,and leaf plasmalemma permeability under non salt stress(0 NaCl) and salt stress(1% NaCl) conditions.The results indicated that SOD activity,MDA content,and leaf plasmalemma permeability of the high salt tolerant materials were significantly lower than that of the low salt tolerant materials.更多还原
