摘要
赤桉(Eucalyptus camaldulensis Dehnh.var.camaldulensis),原产澳大利亚,自然分布15.5°～38°S,海拔30～600m,是澳洲大陆内栽培最广泛的一种桉树。树高25～50m,木材可作板材、建筑材、造纸材和薪炭材,也是蜜源植物和观赏树种,目前全世界栽培赤桉的面积50万hm^2,其中西班牙为11.4万hm^2;摩洛哥为8.7万hm^2;乌拉圭为4.4万hm^2。
In order to select the best provenance of Eucalyptus camaldulensis and provide with the fine seeds for production in Hunan Province, the experiment on E. camaldulensis provenance was made in Spring 1988, with 13 provenances, among which 10 were from Australia, i. e. 15029, 17297, 15441, 13703, 14106, 15223, 15052, 15050, 13941, 15235, and 3 were from local, i. e. 1 from Sichuan, Yunan and Jiangxi respectively. Based on the statistic analysis of 3.5 years' observation, a preliminary appraisal on the growth, cold-tolerance, disease-resistance and stem quality of the young trees was conducted. It indicates that the seed lot No. 15223, 15052 and the seeds from Sichuan Province (Dukou) are better in terms of various characteristics, which could be used in middle experiment and in extension while the others used particularly in tree improvement.
