| 摘 要： | 对融安县西山林场1992年营造的72个杉木(Cunninghamia lanceolata)半同胞家系子代林19年生的树高、胸径和材积指标进行了分析,结果表明:各家系在树高、胸径和材积等生长性状的差异均达到了显著或极显著水平。树高、胸径和材积增益大于对照10%的家系数量分别占参试家系的19.4%、18.1%和31.9%。以生长量差异为依据,筛选出了柳241、柳449、柳428、林朵14、柳244等21个综合增益显著的家系,其最高树高、胸径和材积增益分别达26.75%、23.50%和83.02%。

| Abstract: | The tree height,DBH and volume were analyzed for 19-year-old plantations of seventy-two chinese fir half-sib families planted in 1992 in Xishan forest farm of Rong’an county.The results showed that there were significant or very significant differences among all families in tree height,DBH and volume.The gains of tree height,DBH and volume were more 10% than control in the families which accounted for 19.4%,18.1% and 31.9% of the tested families respectively.According to the differences of growth,twenty-one families such as Liu241,Liu449,Liu428,Linduo14,Liu244 were selected which were highly gains.The highest gain was 26.75%,23.50% and 83.02% in tree height,DBH and volume respectively. |
