空间飞行对藿香过氧化物酶、酯酶同工酶、可溶性蛋白质的影响

目的：探讨空间环境对药用植物的影响。方法：以藿香种子为材料，搭载返回式人造地球卫星，回到地面后研究其过氧化物酶、酯酶和蛋白质的变化。结果：失重组材料的过氧化物酶活性和蛋白质含量与地面组接近，略低于地面对照组，而击中组材料的过氧化物酶活性和蛋白质含量则明显高于地面对照组。３组材料的过氧化物酶和酯酶的电泳图谱基本相同，失重组和地面对照组的蛋白质电泳图谱也基本相同，而击中组材料的蛋白质电泳图谱则与另外两组材料有所区别。结论：微重力对藿香的影响小于高能重离子辐射，不同材料对空间环境的敏感性不同。

Effects of Space Flight on Medicinal Plant Agastache rugosa (Fisch.et Mey.) O. Ktze.

Objective:To substantiate the effect of space conditions on medicinal plants.Methods:The seeds of Agastache rugosa were set up in retrievable satellites. After returning to earth, the changes of isozymes of peroxidases, esterase and soluble proteins were studied.Results:The peroxidase activity and protein content of the weightless group were a little lower than those of the earth controlled group, while these two items of the hit group were higher than those of the earth controlled group.The electrophoresis patterns of isoperoxidases and isoeasterase of these three groups, as well as the protein patterns of the weightless group and the earth controlled group were found alike. But the protein patterns of the hit group were different from those of the other tow groups.Conclusion:The effect of weightlessness is smaller than that of the high energy heavy ions on Agastache rugosa.Different plants have different susceptibility to space conditions.
