摘要
通过盆栽试验研究钼(Mo)、硒(Se)单施及配施对盐胁迫下小白菜抗氧化系统及渗透调节系统的影响。结果表明:施Mo以及Mo、Se配施可以提高盐胁迫条件下小白菜的产量;Mo、Se配施可以提高小白菜的抗氧化能力和渗透调节能力;单施Mo对提高小白菜抗氧化能力和渗透调节能力均有着较好的作用,而单施Se并没有显著的效果。Mo、Se配施对小白菜Mo、Se含量有着显著的正交互效应。因此,Mo、Se配施不但能增强小白菜对盐胁迫的抵御能力,而且还能生产出富硒的蔬菜。
A pot experiment was conducted to investigate effects of applying molybdenum and selenium on antio-xidative defense system and osmotic-adjustment system of pakchoi cabbage under salt stress.The results showed that both Mo and combination of Mo and Se increased yield of pakchoi cabbage.Co-application of Mo and Se increased the capacity of pakchoi cabbage to eliminate active oxygen and increased the ability of osmotic-adjustment of pakchoi cabbage.Single Mo also increased the capacity of pakchoi cabbage to eliminate active oxygen and the ability of osmotic-adjustment of pakchoi cabbage.Single Se had a very small role in enhancing salt stress tolerance of pakchoi cabbage.Mo and Se had synergistic effects on increasing Mo and Se uptaking of pakchoi cabbage.Co-application of Mo and Se not only increased salt tolerance but also produced Se-enriched cabbage.
