摘要
调查了圆齿野鸦椿的江西南昌种源10个家系、江西信丰种源4个家系、福建省建瓯种源15个家系、江西安远种源6个家系、江西大余种源6个家系、福建永泰种源4个家系、江西崇义1个家系共7个种源46个家系一年生容器苗的生长性状,如苗高、地径、主根长度、侧根数量(大于5cm),并对调查结果进行了分析,结果显示:(1)7个种源的生长状况差异极显著,其中江西安远种源苗高、地径、主根长、侧根条数分别为36.0cm、0.446cm、21.0cm、35条,在苗期表现最好;(2)46个家系间生长状况差异显著;(3)利用主成分分析法,初步选育出10个生长较快家系。
Used the variance analysis to analyze the seedling stage growth characters of Euscaphis konishii which had grown for 9 months in the container of 10 pedigrees from Nanchang Jiangxi,4 pedigrees from Xinfeng Jiangxi,15 pedigrees from Jianou Fujian ,6 pedigrees from Anyuan ,Jiangxi ,6 pedigrees from Dayu,Jiangxi,4 pedigrees from Yongtai ,Fujian and 1 pedigree from Chongyi,Jiangxi in total 7 seedling sources and 46 pedigrees. The growth character mainly included the height, the diameter ,the length of taproot, the quantity of side roots （was greater than 5 cm）.The analysis result indicated： （1）There was big variation among the seven seedling sources. In Anyuan ,Jiangxi seedling source, the average number of the height, the diameter , the length of taproot , the quantity of side roots respectively was 36.0 cm,0.446 cm,21.0 cm,35,was the best one. （2） The growth character variation among 46 pedigrees was also positive. （3） Using the principal component analysis; choosed initially 10 pedigrees growing quicker in the period of seedling stage.
