摘要
在福建省洋口国有林场,对14年生的杉木无性系测定林进行调查和分析测定,从参试的60个无性系中选择出2594等10个速生优良无性系,14年生时的树高、胸径、材积平均值分别达15.10 m、21.47 cm和0.302 57 m3,与第2代种子园混合种后代相比,材积的现实增益达24.25%,生长性状表现十分突出,具有广阔的推广应用前景.
Based on the investigation and analysis for a 14 years old clone test plantation of Chinese fir in Yangkou State-owned Forest Farm of Fujian Province, 10 fast growing superior clones of Chinese fir including 2594 were selected from 60 clones. The selected superior clones showed very fast growing rate and their average values for tree height, diameter at breast height and stem volume were 15. 10 m, 21.47 cm and O. 302 57 m^3 respectively. The realistic genetic gain of stem volume for selected superior clones was 24. 25% compared with progeny of the 2nd generation seed orchard of Chinese fir.
