马尾松种子园单亲子代测定研究

Studies on the One-Parent Progeny Test of Pinus massoniana Seed Orchard

对漳平五一国有林场马尾松种子园18个初选家系进行子代测定,采用随机区组设计、8次重复,对6年生的树高、胸径、材积等性状进行测定,试验结果表明:马尾松种子园各家系子代均明显高于对照(CK),共选出7个优良家系材积生长超过对照50%以上材料,作为营建马尾松改良种子园和工业原料林的材料。

The experimental results show that the characters of tree height,dbh,and volume,etc.of every family progenies of Pinus massoniana seed orchard are all evidently higher than those of control (CK),7 fine family materials whose volume growth exceeds the control's by 50% are totally selected as the materials for building P.massoniana improved seed orchard and industrial raw material forest. 
