Physiological and Biochemical Characteristics of Quercus variabilis in Plus Tree Progeny
摘要
Abstract
An investigation was carried out on the variations of the nitrate reductase,soluble protein,chlorophyll as well as soluble sugar of 5-year-old plus trees from open pollinated progenies of Quercus variabilis populations. The results showed that there were significant differences in the nitrate reductase activity,the content of soluble protein,the chlorophyll content and the content of soluble sugar among different populations (P<0. 05). Significant seasonal variations were observed within the same provenance. In July,several physiological indices of families reached their maximum values, and significant differences were found a-mong different families. There existed significantly positive correlations between sapling tree height and other indices, such as the nitrate reductase activity, the content of soluble protein, the chlorophyll content and the content of soluble sugar, and the corresponded correlation coefficients were 0. 547,0. 643, and 0. 492,respectively,which could be used as physiological indices in early selection of Q. variabilis.关键词
