- 摘要:
- 选择1 a生山白兰苗木为试验材料，采用盆栽土培法以不同浓度PEG-6000水溶液对山白兰进行处理，研究PEG-6000对山白兰幼苗生理特性的影响。结果表明：随着PEG-6000浓度的增大，MDA含量增加，SOD和POD都呈现先升后降的变化趋势，游离脯氨酸一直呈上升的变化趋势，可溶性蛋白质呈先升后降再上升的变化趋势。
- Abstract:
- Taking one-year-old Michelia alba seedlings as test materials，pot experiment was conducted，the effects of different concentrations of PEG-6000 aqueous solution on physiological characteristics of Michelia alba seedlings were studied.The results showed that with the increasing of concentrations of PEG-6000 aqueous solution，MDA content increased，SOD and POD content increased first and then decreased，but overall than the control.Free proline had shown a rising trend.The soluble protein content decreased firstly and then increased.
