摘要
为研究不同交趾黄檀家系在采穗圃的生长差异,于2016年在福建省龙海林下国有林场苗圃对21个交趾黄檀家系采穗圃母株生长指标进行调查.结果表明:插穗产量最大的为21号家系,穗条产量达39.42条,比家系平均值高81.24％;交趾黄檀不同家系在主干地径、插穗产量、平均萌芽条数上存在显著或极显著差异;插穗产量与主干地径、主干树高、萌芽条数都存在极显著正相关、与萌芽高度存在显著正相关;采取熵权TOPSIS法,初步选出在采穗圃表现生长快、萌芽能力强、穗条产量高的4个家系(21、16、1、10号).
Abstract
In order to study the growth difference of different Dalbergia cochinchinensis families in cutting orchard,the growth indexes of 21 mother plants of D.cochinchinensis families in the orchard were investigated in the nursery of the state-owned forest farm under the forest in Longhai,Fujian Province in 2016.The results showed that No.21 had the highest yield of cuttings,and the yield of cut-tings was 39.42,which was 81.24％higher than the family average;there were significant or extremely significant differences in main field diameter,yield of cuttings and average number of bud in cutting orchard of D.cochinchinensis family.There were signifi-cant positive correlation between cuttings yield and trunk diameter,trunk tree height,bud number and bud height;four families(21,16,1,10)were selected by entropy weight TOPSIS to show fast growth,strong germination ability and high spike yield.
