| 摘 要： | 目的]研究盐胁迫下不同浓度的锰处理对小麦幼苗生长及SOD、POD活性的影响。方法]以淮麦19号为试材，将小麦种子及幼苗分别用1％的NaCIO溶液和0．1％的NaCI溶液处理后，再喷施不同浓度的硫酸锰溶液（0．5、1．0、1．5、2．0、2．5mg／L），分别测定小麦幼苗的鲜重、根长、根重及叶片中SOD和POD的活性，研究盐胁迫下不同浓度的锰处理对小麦幼苗生长及SOD、POD活性的影响。I结果]不同浓度的锰处理对小麦幼苗根长、苗高、鲜重的影响显著，锰处理浓度为0．5mg／L时小麦幼苗的根长、苗高分别比对照增加了9．6％、9．8％；锰处理浓度分别为0．5、2．0mg／L时，小麦幼苗的鲜重分别比对照减少了25．9％和27．2％；2．0mg／L的锰浓度处理可以显著增加小麦幼苗体内SOD和POD的活性，分别比对照增加了14．1％、25．2％。【结论]该试验提出了合理的小麦施锰肥的技术，为农业生产实际服务。
