A Preliminary Report on Provenance Trial of Eucalyptus camaldulensis

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.
