在北京八达岭林场苗圃，为培养观赏型文冠果大苗，采用无覆盖大棚下容器育苗、大地育苗两种育苗方法，对北京顺义、昌平和河北赤城3个种源的观赏型文冠果幼苗的株高、地茎和芽苗数进行了调查，并对不同生长性状间的相关性进行了分析。结果表明：不同种源的观赏型文冠果1a生苗的株高、地径和芽苗数无显著差异，河北赤城种源幼苗表现稍好，但生长分化严重。为了选择高生长好的乔木型观赏树，早期选择非常必要。生长性状苗高与地径为线型回归关系，芽数与苗高、地径为对数回归关系，其显著性可以用于种源评价与判明育苗、栽植措施对生长的影响。

This paper analyzed the correlation between different growth traits by researching the plant height,ground diameter,and number of shoot buds of ornamental xanthoceras sorbifolia’s seedlings in Shunyi and Changping in Beijing,and Chicheng in Hebei province.The methods of container nursery under non-covered greenhouse and seedlings on the ground were used in the research in order to culti-vate the big seedlings of ornamental xanthoceras sorbifolia in Beijing Badaling Forest Farm.The result shows that there is no significant difference between plant height,ground-diameter,and number of shoot buds in different provenances of“1 a”old seeding of ornamental xanthoceras sorbifolia.The seed-lings in Chicheng,Hebei grew better,but differentiated more in their growth.In addition,early selec-tion is necessary for choosing higher growth of arbor ornamental tree.There was a linear regression be-tween plant height and ground diameter.The number of shoot buds had logarithm regression to plant height and ground diameter.The significance of these regressions could be used to evaluate the prove-nance and ascertain effects of cultivation and plantation technology on the growth.
