Comparison of Growth in Cutting Orchard of the Family of Dalbergia cochinchinensis

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 cuttings 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 significant 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.
