大花序桉种源遗传变异及适应性研究
Study on the Variation and Adaptability in Provenance of Eucalyptus cloziana
摘要
Abstract
5.5 year-old Eucalyptus cloziana of provenance trail in Yulin and Qinzhou locations as the researched material,analyzed the growths variance of different provenances,and evaluated the adaptability of provenance.The results showed that:all provenances planted in Yulin showed a better growth than that in Qinlian, which the average values of height、DBH and tree volume were 1 1%,18% and 45% higher than that in Qinlian. In addition,both in Yulin and Qinlian,the differences of height,BHD and volume among provenances,locations and groups were significant.For DBH and single tree volume,the interaction effect of provenance × site had significant difference,but for height,it had no significant differences.Moreover,according to yield and stability parameters,the 18 provenances were divided into four types,which were important guiding significance for matc-hing species with the site of Eucalyptus cloziana.关键词
