| 摘 要： | 目的]为了解亚精胺是否能缓解盐胁迫对小麦幼苗生长的影响。方法]采用滤纸培养法,研究了外源亚精胺（Spd）对NaCl胁迫下小麦幼苗生长和部分生理指标的影响。结果]与对照相比,盐胁迫抑制了小麦幼苗的生长,增加了小麦中SOD、POD活性和MDA含量,降低了可溶性蛋白质含量。亚精胺处理明显促进了小麦幼苗的生长,提高了幼苗中SOD和POD活性,降低了MDA含量,提高了可溶性蛋白质含量。结论]亚精胺能缓解盐胁迫对小麦幼苗的毒害作用,提高小麦幼苗的抗盐能力,但随处理时间的延长,亚精胺的缓解作用有所下降。

| Abstract: | Objective] The research aimed to study whether spermidine(Spd) could relieve salt stress on wheat seedling.Method] The seedlings growth and some physiological indices were determined under exogenous spermidine and NaCl stress by means of filter paper culturing methed.Result] NaCl stress restrained the growth of seedlings,enhanced SOD and POD activity,increased MDA content,and decreased the amount of soluble proteins.Spermidine apparently promoted the growth of wheat seedlings and raised SOD and POD activ... |
