摘 要 ：目的:探讨空间环境对药用植物的影响。方法:将药用植物红花的种子搭载于返回式人造地球卫星上,返回地面后对种子的出苗率和生长发育状况进行观察。结果:失重组和重离子射线贯穿1次以下组的材料出苗快、出苗率高、植株较高、每株的分枝数多;而2～3次贯穿组的材料的这些指标则不及地面对照组。结论:说明微重力和少次重离子击中与贯穿对红花的生长发育有一定的促进作用,而多次贯穿则作用相反。

Abstract:Objective:To substantiate the effects of space condition on medicinal plants.Method:The seeds of medicinal plant Carthamus tinctorius were carried on board a retrievable satellite during 3～18 July,1994.After returning to earth,the seeding rate,state of growth and development were observed.Result:The seeding rates,plant heights and branch quantities of weightless seeds and the seeds which were penetrated once and less than once by the heavy ion rays were higher than those of the seeds which were kept on earth,but these indexes of the seeds which were penetrated 2～3 times by the heavy ion rays were higher than those of the ground controlled seeds.Conclusion:Weightlessness and little penetration promote the growth and development of Carthamus tinctorius,but much penetration functions the other way round.
