摘要/Abstract

摘要： 在NaCl胁迫下, 对番茄嫁接苗和自根苗的保护酶活性、渗透调节物质含量及光合特性等进行了比较。结果表明, 番茄嫁接苗叶片超氧化物歧化酶( SOD) 、过氧化物酶( POD) 和抗坏血酸过氧化物酶(APX) 活性以及抗坏血酸(AsA) 含量均显著高于自根苗, 丙二醛(MDA) 含量显著低于自根苗; 嫁接苗叶片游离脯氨酸、可溶性糖和可溶性蛋白质含量均显著高于自根苗; NaCl胁迫抑制光合作用, 但嫁接苗仍表现出优势; 嫁接苗根系Na + /K+比值显著低于自根苗。以上结果表明, 嫁接苗耐盐性优于自根苗。

Abstract: Comparison of the activities of protective enzymes, contents of osmotic adjustment substances and photosynthetic characteristics was made between grafted and self-root tomato (Lycopersicon esculentum Mill. ) seedlings under NaCl stress. The results showed that activities of superoxide dismutase (SOD) , peroxidase ( POD) , ascorbate2specific peroxidase (APX) and content of ascorbic acid (AsA) in leaves of grafted seedlings were significantly higher than those of self-root seedlings. Malondiadehyde (MDA) content in leaves of grafted seedlings was significantly lower than that of self-root seedlings. The contents of free proline, soluble sugar and soluble protein in the leaves of grafted seedlings were significantly higher than those of self-root seedlings. Photosynthesis was inhibited under NaCl stress, but the performance of the grafted seedlings was superior to that of self-root seedlings. The Na⁺/ K⁺ value in the roots of grafted seedlings was significantly lower than that of self-root seedlings. Base on these results, it could be concluded that the resistance to NaCl stress of grafted tomato seedlings was stronger than that of self-root seedlings.
