    摘要:

    本试验通过采用不同浓度的NaCl和Na2CO3胁迫萌发期的西兰花(Brassica oleracea L.var.botrytis L.)种子,调查了其发芽和胚保护酶活性等指标。研究结果表明,低浓度(≤20 mmol/L)的NaCl胁迫对西兰花各发芽指标有促进作用,在等Na+浓度胁迫下,各Na2CO3胁迫对各发芽指标均表现出抑制作用。Na2CO3胁迫处理胚的SOD和POD活性低于NaCl胁迫处理,MDA含量高于NaCl胁迫处理。综合分析表明,西兰花耐盐阈值和耐碱阈值分别为445.5 mmol/L和64.1 mmol/L。

    Abstract:

    The germination and protection enzyme activities of Brassica oleracea L.var.botrytis L.embryo under the different concentration of NaCl and Na2CO3 stress were examined in this experiment.The results showed that the germination of broccoli was promoted under the low concentration of NaCl(≤20 mmol/L).Germination of broccoli was inhibited under the Na2CO3 stress when concentration of Na+ was the same.SOD and POD activities of embryo under the Na2CO3 stress were lower than the NaCl stress,and MDA content was higher than the NaCl stress.Comprehensive analysis showed that the threshold values of broccoli tolerance to NaCl and Na2CO3 were 445.5 mmol/L and 64.1 mmol/L.
