稀土元素能缓解水分胁迫下小麦幼苗叶片渗透势的降低,减少离子的渗漏,明显提高抗旱性.经过稀土处理的小麦幼苗,体内超氧物歧化酶和过氧化物酶活性减弱.抗旱品种比不抗旱品种膜脂过氧化程度低,丙二醛在叶片中积累减少,表现出明显的差异.
Rare earth elements can alleviate the decrease of osmotic potential of wheat seedling leaves under water stress, reduce the leakage of ions and increase the drought resistance significantly.Rare-wheat seedlings treated with rare earth reduced the activity of superoxide dismutase and peroxidase in the body. Non-drought-resistant varieties of membrane lipid peroxidation is low, malondialdehyde accumulation in the leaves decreased, showed significant differences.
