不同种源巨桉幼林生长性状变异和早期评价
Growth Traits Variation Analysis and Early Evaluation of Eucalyptus grandis Seedling of Different Provenance
摘要
Abstract
In Danan Mountain forest farm of Guangdong Province,the experiment was conducted to select superi-or provenances of Eucalyptus grandis from 20 Australian provenances,and then analyzed the tree height and diameter of 3.5-year-old seedlings in 2012.Results showed that the variation of DBH,tree height and volume of wood incre-ment were significant among the provenances,and there was significant positive correlation between the DBH,tree height and volume.The largest growth of all provenances was No.18696 (Queensland provenance),the average value of the DBH,tree height,and volume were 7.723 3 cm,6.750 0 m,0.020 4 m3 ,respectively,Those were 102.66%, 104.66%,108.11% of the population means,and the variable coefficient reached to 31.58%,26.48%,72.63%, respectively.Through the method of synthetic weighted mark,4 superior provenances were selected,which were No. 18696 (Queensland),20917 (New South Wales),16892 (Queensland),and 20668 (Queensland).关键词
