摘要: <正>对全国第一批杉木优良家系区域试验黄山试点112个家系10年生林分的调查分析表明,杉木主要生长性状与木材密度无显著相关,具相对独立的遗传性,为生长量与材性进行综合选择提供了依据。综合各性状选出的13个杉木优良家系,树高、胸径、材积遗传增益分别达98%、79%和289%。木材密度比群体均值提高35%(0.5%~13.0%)。

Abstract: Based on 10year investigations, the growth and wood density were analyzed for 112 families of Chinese fir at the yellow mountain where one of the first national regional testing locations was located. A slight negative correlation (-0.009~-0.088) was examined between growth and wood density. So it was clear that the growth traits were independent on wood density, which made it possible to select superior families of individuals which had good properties on both growth and wood density. Thirteen families were selected when growth and wood density were taken into account, 9.8%, 7.9% and 28.9% genetic gains for height, DBH and Volume index respectively were to be obtained, and the wood density of 13 selected families was 0.5%~13.0% (3.5% on average) higher than that of the population mean.
