杨树苗木蛋白质与内源激素的动态变化研究
The Dynamic Changes of Proteins and Some Endogenous Hormones in Seedlings of Poplar
摘要
Abstract
[Objective]The research aimed to study the dynamic changes of proteins and some endogenous hormones in seedlings of poplar. [Method]The dynamic annual changes of the total protein in leaf and cortex of seedlings' stem were investigated based on one-year-old poplar clone 797(P. deltoides×P. euramericana) seedlings. And meantime some endogenous hormones' contents were also measured by ELISA. The relationship between the endogenous hormones and protein's content was analyzed. [Result]The results showed that the changing trends were opposite between the endogenous hormones and protein's content in leaf and cortex of seedlings' stem. In spring the total protein's content in leaf was higher more than that in cortex. While in autumn and winter, it was low in leaf and began to accumulate in cortex. The endogenous hormones' seasonal change was fluctuant greatly. And it related nearly to the total proteins. And the endogenous hormones regulated indirectly the degradation and synthesis of vegetative storage proteins(VSP). [Conclusion]The study explored the regulatory effect of the endogenous hormones during nitrogen metabolism of poplar.关键词
