【摘要】 [目的]对2个回归样地内8个不同种源厚朴幼苗生长适应性进行评价,为厚朴野生资源回归保护提供科学依据。[方法]观测幼苗生长性状指标,并运用主成分分析和灰色关联分析评价其回归适应性。[结果]表明:(1)厚朴回归苗木与理想种关联度为0.794 7;(2)1号回归样地(浙江磐安)和2号回归样地(浙江遂昌)与理想种关联度分别为0.774 1和0.815 4;(3)8个回归种源与理想种关联度由高到低分别为:浙江遂昌>浙江磐安>浙江安吉>福建光泽>杂交幼苗>江西庐山>福建建宁>江西铜鼓种源。[结论]厚朴野外回归幼苗总体长势良好,适应性较好,不同种源、同一种源在不同回归样地内生长差异较大,回归幼苗来源和回归地可能是影响其回归保护的关键因子。更多还原

【Abstract】 [Objective] In order to provide evidence for the protection of Houpoёa officinalis wild resources,this study evaluated the adaptability of 8 H. officinalis provenances at two reintroduction sample plots which located at Pan’an and Suichang of Zhejiang Province). [Method] Botanical characteristics including plant morphology and growth situation were observed and principal component analysis and gray-correlation analysis were used to evaluate the seedlings adaptability of reintroduction. [Result](1) The correlation coefficients of H. officinalis seedling in the process of reintroduction to the ideal species was 0.794 7;(2) The correlation coefficients of the two reintroduction sample plots to the ideal species was 0.774 1(Pan’an) and 0.815 4(Suichang);(3) The correlation coefficient of 8 H. officinalis provenances with the ideal species from high to low were Suichang provenance from Zhejiang Province, Pan’an provenance from Zhejiang Province, Anji provenance from Zhejiang Province, Guangze provenance from Fujian Province, hybird seedling, Lushan provenance from Jiangxi Province, Jianning province from Fujian Province and Tonggu provenance from Jiangxi Province. [Conclusion] The H. officinalis seedling in the process of reintroduction has good growth and good adaptability. The adaptability differed in different provenances and different habitats, the origin population and destination area for reintroduction may be the main factors affecting reintroduction.更多还原
