为了给叶用喜树栽培提供科学与实践依据 ,采用 1 6个喜树地理种源的 1年生壮苗上山造林和苗床截干 2种处理方法 ,测定幼树和萌芽条的生长量。结果表明 :幼树高生长量第1名至第 5名依次为湖南长沙、福建屏南、湖北武昌、浙江丽水和浙江临安种源 ,根径与树高间相关系数以贵州贵阳种源最大。截干后萌芽条总的萌芽率为 69 3% ,第 1名至第 5名依次为浙江临安、浙江开化、浙江丽水、江苏南京林业大学和安徽东至种源 ,萌芽条的根径与高生长间相关性都呈紧密相关。表 7参 3
In order to provide scientific and practical basis for the use of Camptotheca acuminate for leaf cultivation, the growth of young tree and sprout was determined by 1 year-old strong seedling afforestation and seedbed truncation of 16 camptotheca acuminata provenance sources. The results showed that the first to the fifth highest seedling growth rates were Changsha, Hunan, Pingnan in Fujian, Wuchang in Hubei, Lishui in Zhejiang and Lin’an in Zhejiang. The correlation coefficient between root diameter and tree height was the highest in Guiyang, Guizhou. The total germination rate of germinated buds after stemming was 69 3%. The first to the fifth place were root diameter and high germination of Lin’an, Zhejiang Kaihua, Zhejiang Lishui, Nanjing Forestry University of Jiangsu and Anhui Province, respectively The correlation between growth are closely related.
