喜树地理种源苗期优势分析

Superiority of Camptotheca acuminata Seedlings

从１９９５年１０月开始，选择中国南方的广东、福建、浙江、安徽、江西、湖南、贵州、云南、湖北和江苏１０个省的１８个喜树种源，于１９９６年在浙江省湖州市林科所苗圃，进行１年生播种苗的苗期优势研究，对半月高生长量进行统计分析，对苗期冻害进行观察。

From October in 1995,seeds of 18 provenances of  Camptotheca acuminata were collected from Guangdong,Fujian,Zhejiang,Anhui,Jiangxi,Hunan,Guizhou,Yunnan,Hubei and Jiangsu in southern China,and were sowed in the nursery of Forestry Research Institute of Huzhou City,Zhijiang In 1996,an observation was carried out about freezing damage of the seedlings and an analysis was made with respect to superiority and high increment of annual seedlings Results showed that the provenances in Wuchang Hubei and in Lishui Zhejiang demonstrated superiority
