| 摘 要： | 以川续断种子为材料,研究川续断种子发芽过程中的部分生理指标变化,探讨盐胁迫对川续断种子发芽的影响,为川续断的生产和研究提供一些基础材料。结果表明:随着盐浓度的升高种子的发芽率逐渐下降;随着川续断种子萌发时间的延长,种子的含水量逐渐增加,可溶性糖含量从第5天起迅速升高,之后缓慢下降;可溶性蛋白质、游离氨基酸总体呈上升趋势;丙二醛(MDA)含量先升高后下降的变化过程;超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性整体都表现出上升趋势。

| Abstract: | This paper discusses the influence of salt stress on Dipsacus asperoides seed germination by germination.The changes in physiological indexes of Dipsacus asperoides during seed germination were studied,so as to provide some basic materials for the production and research of Dipsacus asperoides.The results showed that,with the increase of salt concentration,the seed germination rate decreased;with the extension of seed germination time,the seed water content increased gradually,the content of soluble sugar from the fifth day increased quickly,and then decreased;soluble protein and free amino acids overall showed an increasing tendency as a whole;the activity of SOD,POD and CAT increased gradually. |
