摘要
目的 通过对藿香叶绿体超微结构的研究,探讨空间环境对药用植物的影响。方法 以药用植物藿香的种子为材料,搭载返回式卫星,回到地面后用电镜观察其叶绿体的变化。结果 地面对照组细胞的叶绿体中常含有囊泡,而失重组和击中组细胞的叶绿体中则很少或缺失。失重组细胞的叶绿体有解体的表现。结论 空间环境对藿香叶绿体的超微结构有一定的影响。
To substantiate the effects of space condition on medicinal plants,the seeds of Agastache rugosa were set up in retrievable satellites. Methods After returning to earth,the ultrastructural changes of chloroplasts were examined by means of electron microscope. Results Vesicles could be seen in the chloroplasts in the cells of earth controlled group,it was few and could not be found in the chloroplasts in the cells of weightless group and hit group.Some chloroplasts were degrading in the cells of weightless group,but this phenomenon was not observed in the cells of the other two groups. Conclusions These results showed that space environment had some effect on the ultrastructure of chloroplasts in Agastache rugosa.
