Ca2+和Sr2+联合处理对油菜抗氧化酶活性的影响
Effects of Combined Treatment of Ca2+ and Sr2+ on Antioxidant Enzymes Activities of Oilseed Rape Seedlings
摘要
Abstract
[Objective]The research aimed to investigate the effects of combined treatment of Sr2+ and Ca2+ on antioxidant enzymes activities of oilseed rape seedlings.[Method]Three-leaf stage oilseed rape seedlings ( Brassica napus L. cv. Mianyou No. 15) were raised in quartz-hy-droponic culture system, and a solution containing 0, 10, 20 or 40 mmol/L SrCl2, and 0, 5 or 10 mmol/L Ca ( NO,) 2 was applied. Three antioxidant enzymes (POD, CAT and SOD) activities were determined after 0, 7, 14 and 21 d of the combined treatment of Sr2* and Ca2*.[Result]POD, CAT and SOD activities were increased gradually with the increase of Ca2* concentration. Ca2* could alleviate the deleterious effect induced by Sr2* in oilseed rape seedlings.[Conclusion]The strontium accumulation capability of oilseed rape was explained from the perspective of antioxidant rapeseed, providing a theoretical basis for the use of oilseed rape phytoremediation of strontium to cleanup the polluted environments.关键词
