| 摘 要： | 湿地松(ＰｉｎｕｓｅｌｌｉｏｔｔｉｉＥｎｇｅｌｍ)是优良的纸浆材与建筑材树种,对湿地松的遗传改良,过去侧重于生长性状方面,材性改良仅做了些基础性的工作(管 宁等,1993)。本研究旨在探索湿地松半同胞家系生长、形质和木材性状的遗传变异规律,并利用选择指数,按不同材种(纸浆材、建筑材)培育目标,选择一批生长、形质和材性均优良的湿地松半同胞家系供生产上推广应用。1 材料与方法湿地松半同胞家系测定林设置在湖南省汨罗市桃林林场,属湿地松最适宜引种区。试验于1981年造林,完全随机区组设计,5次重复,6株单行小区,株行距3ｍ×3ｍ。共…

| Abstract: | The study on half|sib family's experimental forest of slash pine shows that there are obvious difference among height, diameter, volume, bole form, branch size, timber density, tracheid length and so on with changed families. At family level, the timber density was negatively ralated to volume growth while there was no obvious relation between tracheid length and volume growth. Based on constrained and unconstrained selection indexes, different demands for pulpwood and construction timber, the following integrated selection results were got:families No.0 508 #, 0 1027 #, and 2 46 # are most suitable for planting pulpwood forest; families No.0 464 #, II 101 # and 0 508 # are the best selection for establishing construction timber forest. |
