| Abstract: | The two-year-old Seedlings of Toona sinensis from 11 geographical provenances were introduced and cultivated in Ruichang city,Jiangxi and the annual growth of young seedlings were investigated and analyzed in this paper.The results showed that there were significant differences of tree height and basal diameter between provenances of T.sinensis.Based on the height and basal diameter growth and the survival rate as well as the disease and insect pest occurrence of various provenances,the two provenances,Fujian Xiapu provenance and Hunan Donko provenance,were primarily selected as superior provenances in Jiangxi. |
