[The effects of space flight on medicinal plant Datura innoxia]
1Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing.
Objective:
To probe the effects of space condition on medicinal plants.
Methods:
The seeds of Datura innoxia Mill were put in a retrievable satellite. After returning earth, the isozymes of peroxidases, esterase and soluble proteins were studied.
Results:
The peroxidase activity and the protein content of weightless group were lower than that of the earth controlled group, but these items of the hit group were higher than that of the earth controlled group. The electrophoresis patterns of isozymes and proteins of these three groups were similar.
Conclusion:
The effects of weightlessness and the high energy heavy ions were different on Datura innoxia, and the effects of space conditions were not enough to produce idiovariation in Datura innoxia.
