Stability evaluation on tree height for introduced provenances of Corymbia citriodora subsp.variegata
摘要
Abstract
[Objective]This study evaluates the adaptability and stability of Corymbia citriodora subsp.variegata(CCV)provenances introduced to Guangxi,China,providing a theoretical basis for their selection and extension.[Method]The tree height of six-year-old CCV specimens established in Nanning,Yulin and Liuzhou was measured.An analysis of tree height and survival for each provenance was conducted to assess growth adaptability.The additive main effects and multiplicative interaction(AMMI)model and genotype main effect plus genotype-environment interaction(GGE)biplot were employed to analyze the stability of provenances,classify suitable extension areas,and identify superior provenances.[Result]The average tree height of all CCV provenances in sixth years was 13.0 m,with individual provenance survival rates ranging from 21.23％to 54.81％.Significant differences were observed in tree height among provenances,and the interaction with the site was also significant,suggesting a need for further decomposition of the interaction effect.The AMMI model results indicated that one interaction principal component axis achieved a significant level,accounting for 79.9％of the interaction effect.The stability Di index for each provenance was calculated,revealing the following order of stability ranking:19694,19691,20883,19664,20396,20756,20787,20753,19665 and 19666.Provenances 20883,20756 and 19694 were identified as fast-growing and stable.The GGE biplot demonstrated that the three trial sites could be divided into two ecological regions,with Nanning and Yulin falling within one region and Liuzhou representing the other.Provenance 20883 emerged as the most suitable provenance for introduction to Guangxi.[Conclusion]The CCV provenances introduced to Guangxi exhibited strong growth adaptability.The selection of provenances can significantly enhance planting outcomes.Provenances 20883,20756 and 19694 are recommended for Nanning and Yulin,while provenance 20787 is suitable for Liuzhou.关键词
