摘  要:
[目的]考察盐胁迫对桑叶中1-脱氧野尻酶素含量的影响。[方法]以黑龙江省桑树品种青龙桑为试验材料,采用不同盐浓度下对桑苗进行盐胁迫处理,利用高效液相色谱测定1-脱氧野尻酶素的含量。[结果]不同浓度的NaCl胁迫下桑树叶片的1-脱氧野尻酶素含量均高于对照,其中50 mmol/L NaCl溶液处理下桑树叶片中1-脱氧野尻酶素含量在第31天达到最大值,为1.51 mg/g;并且,在NaCl胁迫下桑树上部叶的1-脱氧野尻酶素含量大于下部叶。[结论]适当的盐浓度能有效提高桑苗叶片中1-脱氧野尻酶素的含量。

摘  要:
[Objective] To investigate effects of salt stress on 1-DNJ content in mulberry leaf.[Method] With Heilongjiang mulberry variety Qinglongsang as test material,different concentration salt stress treatments were conducted.HPLC method was used to determine 1-DNJ content.[Result] The results showed that the DNJ contests of mulberry is higher than CK under the salt stress,and 50 mmol/L NaCl mulberry leaf in solution with DNJ contents reach maximum 1.51 mg/g after 31 days.Under NaCl stress,1-DNJ content in upper leaves of mulberry is higher than that of the lower leaves.[Conclusion]The appropriate salt concentration can effectively improve 1-DNJ content in mulberry leaf.
