叶面施锰对豌豆膜脂过氧化作用及膜保护系统的影响

Effect of Foliage Spraying Manganese on Peroxidation of Membranes and the Membrane Defensive System of Pisum Sativum

豌豆不同生长期用不同浓度的硫酸锰溶液进行叶面喷施.结果表明,在幼苗期、现蕾期和开花期喷施不同浓度硫酸锰溶液,能增强豌豆叶片的SOD活性和CAT活性,降低O2.-生成速率和MDA含量;于开花期前喷施最为有效的硫酸锰溶液质量百分浓度为0.1%-0.2%.

In different growth periods, the different concentraetions of manganese sulfate solutions are sprayed on the surface of leaves of Pisum Sativum. The resuhs show that the activity of SOD, CAT is promoted, the content of MDA and the speed of O2W^- production are rcduced in seeding, buding and flowering periods. Spraying 0.1% -0.2% of manganese sulfate solution on the surface of leaves of Pisum Sativum is best before flowering period.
