摘要
通过模拟不同土壤含水量条件,对侧柏和油松幼苗内的渗透调节物质与保护酶的变化进行研究。结果表明:渗透调节方面,脯氨酸对植物的保护侧柏好于油松,可溶性糖对侧柏和油松适应干旱逆境起到了较好的保护作用;在保护酶变化方面,侧柏在SOD和POD变化上都优于油松。
The effects of different soil water content on the osmotic adjustment substances and protective enzymes in Platycladus orientalis Pinus tabulaeformis seedlings were studied.Result shows that function of osmotic adjustment of proline in Platycladus orientalis is optimal than that in Pinus tabulaeformis;soluble sugar have optimal protective effects on arid stress of Platycladus orientalis and Pinus tabulaeformis.The changes of SOD and POD of Platycladus orientalis are optimal than those of Pinus tabulaeformis.The drought resistance of Platycladus orientalis is optimal than that of Pinus tabulaeformis.
