硝酸还原酶和可溶性蛋白对蒙古栎种源生长的影响

研究了硝酸还原酶和可溶性蛋白含量对蒙古栎种源生长的影响.结果表明:蒙古栎在生长性状、硝酸还原酶活性以及可溶性蛋白含量上都存在着显著的差异,绥阳种源含量最高.同时,不同种源的硝酸还原酶活性及可溶性蛋白含量呈现明显的季节变化,以6月份最高,这与蒙古栎在6月份生长较快相符.而且生长性状与所研究的两个理化指标之间存在显著的正相关,即树木生长潜力大的种源、体内硝酸还原酶活性高、蛋白质积累多.本研究为人们预测树木生长状态,提供了一定的理论依据.

The influence of nitrate reductase and soluble protein on the provenance growth of Quercus mongolica

The influence of nitrate reductase and soluble protein content on provenance growth of Quercus mongolica was investigated. The result shows that growth characteristics, nitrate reductase activity and soluble protein content have significant differences among the samples, the provenances of Suiyang possess the biggest value. Meanwhile, nitrate reductase activity and soluble protein content of different provenances vary with the seasons obviously. They have maximum values in June, which coincide with the fastest growth velocity. There is prominently positive correlation between the growth characteristics and the two physiological and biochemical factors, The provenances with stronger growth potential have higher nitrate reductase activity and more protein content. This investigation has provided fundamental information of predicting the growth state of Quercus mongolica.
