摘要:

【目的】对引种至广西的斑皮柠檬桉(Corymbia citriodora subsp. variegata)种源进行适应性和稳定性评价,为斑皮柠檬桉的选择和推广提供理论依据。【方法】对建立在南宁、玉林和柳州的6年生斑皮柠檬桉种源试验林进行树高测定,分析其树高生长和保存率,以评价种源的生长适应性;通过主效可加互作可乘(AMMI)模型和基因型主效应加基因型与环境互作(GGE)双标图分析种源的稳定性,划分适宜推广区域,筛选优良引种种源。【结果】斑皮柠檬桉6年生时所有种源的树高均值达13.0 m,各种源存活率为21.23%~54.81%。树高在种源间存在极显著差异,种源与地点的交互作用显著,有必要进一步进行分解,AMMI模型分析结果显示有1个互作效应主成分轴达到极显著水平,解释了79.9%的互作效应。根据稳定性的定量指标(Di),10个种源的稳定性由大到小排序依次为19694、19691、20883、19664、20396、20756、20787、20753、19665和19666号,其中20883、20756和19694号种源为速生稳定型种源。GGE双标图分析结果显示,3个试验点可划分为2个立地环境区,南宁和玉林试验点划分为同一立地环境区,柳州试验点单独划分为一个立地环境区,20883号种源为所有引种至广西种源的最优种源。【结论】斑皮柠檬桉引种至广西后在各试验点表现出良好的生长适应性,对种源进行选择可获得较好的改良效果;20883、20756和19694号种源适宜在南宁和玉林试验点立地环境相似的地区推广,20787号种源适宜在柳州试验点立地环境相似的地区推广。

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.
