桉树与针叶树、阔叶树生理生化指标季节变化的比较
Comparative study on seasonal changes in physiological characteristics of Eucalyptus, broad-leaved and coniferous tree species
摘要
Abstract
The seasonal changes in physiological and biochemical characteristics of Eucalyptus, coniferous and broad-leaved tree species were studied at Lingtian Village of Guilin City, Guangxi Zhuang Autonomous Region. The results showed that the physiological and biochemical norms changed according to seasons in Eucalyptus and other four tree spe-cies. The SLA of five species was the highest in the summer and lowest in winter. The average SLA values were Eucalyp-tus >Castanopsis hystrix>C. fissa>Cunninghamia lanceolata>Pinus massoniana. Leaf chlorophyll of seasonal changes was as follows:summer>autumn>spring>winter. The average of total chlorophyll in four seasons were:Eucalyptus>Castanopsis fissa>C. hystrix>Cunninghamia lanceolata>Pinus massoniana. The SS with seasonal changes were:sum- <br> mer > spring > winter > autumn;the SP contents of the five species were the highest in spring and the lowest in sum-mer, and the SP in coniferous were much higher than the broad-leaved species. The average SS and SP were the highest in Eucalyptus. Seasonal trends showed arched leaf RNA variation, the order of change was summer>spring>autumn>winter, with average maximum NRA in Eucalyptus. To sum up, in a natural environment for the growth, physiological and biochemical indices of these five species response to season were different, but the physiological indicators of Euca-lyptus were generally higher than other species, which inflected that the artificial Eucalyptus forest had high productivity and growth advantage.关键词
