摘　　要：对正常条件和模拟微重力条件下拟南芥幼苗的生长状况进行了研究,发现拟南芥幼苗的生长发育、生理生化特性、酶活性等均发生一系列的变化。并利用qRT-PCR技术深入研究了经模拟微重力处理的幼苗过氧化物酶的基因表达量的变化。这些结果为植物在受控生态生保系统中的生长提供了试验支持。Microgravity in space environment is an important factor that can affect plant growth and development.Based on the normal conditions and under the conditions of simulated microgravity on growth of Arabidopsis and found that Arabidopsis growth and development,physiological and biochemical characteristics,activity and so produce a series of changes.Using qRT-PCR technology in-depth study of the peroxidase activity with gene expression changes.These results provide experimental support for the growth of the plants in the controlled ecological life support system.
