Early Growth Evaluations of Different Aquilaria sinensis'Qi-Nan'Strains in Xishuangbanna
摘要
Abstract
In order to provide scientific basis for improved variety selection of Aquilaria sinensis'Qi-Nan'in Dai autonomous prefecture of Xishuangbanna,Yunnan,25 A.sinensis'Qi-Nan'strains were selected as experi-menal materials.Preservation rate,diameter at breast height(DBH),tree height and tree height-DBH ratio were investigated after 3.5 years of planting.Correlations among these traits were analyzed,cluster analysis was used for classification,and principal component analysis and membership function analysis were employed to select superior strains suitable for promotion and cultivation.Results showed that there were significant differences in preservation rate,DBH,tree height and tree height-DBH ratio among different strains.Jin SY strain had the highest preservation rate(96.25%),while Xiao YZ strain had the lowest preservation rate(53.75%).Da YP strain had the largest DBH(6.61 cm),while Ao S strain had the smallest DBH(4.43 cm).Da YP strain had the highest tree height(5.07 m),while Xiao YZ strain had the lowest tree height(3.59 m).Qian LX strain had the highest tree height-DBH ratio(0.97),while You YZ strain had the lowest tree height-DBH ratio(0.68).Preser-vation rate was significantly positively correlated with DBH,tree height and tree height-DBH ratio.DBH was significantly positively correlated with tree height and significantly negatively correlated with tree height-DBH ratio.Tree height was significantly positively correlated with tree height-DBH ratio.Cluster analysis revealed that group 1(Jin Sha Y,Pu TT,Qi NYH,Jin SZ,Lan BS,Jin SY and Tou DL)and group 4(Hei ZZ and Da YP)strains performed better in both preservation rate and growth traits.Jin SY,Lan BS,Da YP,Qian LX and Jin SZ strains exhibited good early growth performances in Dai autonomous prefecture of Xishuangbanna and had high-er potentials for promotion.关键词
