卫星搭载牛膝种子SP1植株的生物学特性

摘要/Abstract

摘要： 利用返回式卫星搭载牛膝种子为材料，研究卫星搭载对其SP1植株生物学特性的影响。种子发芽出苗后调查植株的部分农艺学性状、测定某些生理生化指标并分析几种同工酶谱的变化。搭载种子获得的牛膝植株生长旺盛，植株株高比对照高；叶绿素a、叶绿素b、可溶性糖、脯氨酸、可溶性蛋白质以及赤霉素含量与对照相比均有不同程度的差异；卫星搭载的牛膝中有1株的SOD同工酶谱缺失一条谱带；有3株的CAT同工酶谱带比对照牛膝明显减少；Amy的同工酶谱带与对照牛膝基本一致，但有3株的Amy活性高于对照。由卫星搭载牛膝种子获得的SP1植株与对照植株有明显差异

Abstract: The seeds of Achyranthes Bidentata from recoverable satellite were used in this study. The agricultural characters of SP1 from the seeds were observed, and the physiological and biochemical indexes which were chlorophyll a and chlorophyll b, soluble sugar, proline, soluble proteins and gibberellin in SP1 were detected, the isoenzymes(super-oxide dismutase, catalase and amylase) were analyzed by PAGE. The results showed that the outer-space environment maybe cause the different variations of the SP1 compared with the control. One SOD isoenzyme band lacked in HT-2 compared with those of the others. The CAT isoenzyme bands in HT-1, HT-2 and HT-3 were much fewer than those of the control, while the Amy isoenzyme bands were almost identical to the control, however, the Amy activities of HT-1, HT-2 and HT-3 were higher than those of the control. The SP1 from the seeds of Achyranthes Bidentata carried by recoverable satellite obviously differed from the control in some biological characters.
