A Study on the Biomass Variance and Comprehensive Evaluation at the Seedling Stage of Fokienia hodginsii Provenances

  • Received Date: 2001-08-15
  • The first provenance test at seedling stage was carried out at Dongxing Nursery in Yongtai County,Fujian Province and at the Center of Science and Technology in Ningyuan County,Hunan Province in 1997 with the seeds of 16 provenance collected from the whole distribution area of fokienia hodginsii in 1996. Seedling biomass at the first year and relative traits were observed and the relationship among traits was analyzed. The results are as follows:(1)there was very significant difference on the seedling biomass among provenances which was mainly controlled by genetic factors and related to geographic factors in original regions of different provenances and varied gradually with latitude; (2)there was extreme significant correlation between different traits of seedling biomass; (3)two superior provenances——Fujian Longyan and Fujian Xianyou were tentatively selected in Young Tai Nursery and two superior provenances——Fujian Longyan and Hunan Daoxian were also tentatively selected in Ningyuan Nursery with comprehensive index selection.

Abstract: The first provenance test at seedling stage was carried out at Dongxing Nursery in Yongtai County,Fujian Province and at the Center of Science and Technology in Ningyuan County,Hunan Province in 1997 with the seeds of 16 provenance collected from the whole distribution area of fokienia hodginsii in 1996. Seedling biomass at the first year and relative traits were observed and the relationship among traits was analyzed. The results are as follows:(1)there was very significant difference on the seedling biomass among provenances which was mainly controlled by genetic factors and related to geographic factors in original regions of different provenances and varied gradually with latitude; (2)there was extreme significant correlation between different traits of seedling biomass; (3)two superior provenances——Fujian Longyan and Fujian Xianyou were tentatively selected in Young Tai Nursery and two superior provenances——Fujian Longyan and Hunan Daoxian were also tentatively selected in Ningyuan Nursery with comprehensive index selection.
