摘要: 为了解不同种源阴香Cinnamomum burmannii植株的表型特征和多样性,以全国范围8个种源地的阴香为试材,对其冠型、叶片、枝干和株高等22个生物学表型性状指标进行测定,通过相关性和差异性分析研究其表型变异。结果表明,在22个生物学表型性状指标中,株高、地径、叶柄长度和叶长等表型性状指标具有显著差异。结合株高、地径、叶柄长度和叶宽的差异性分析来看,韶关和建瓯种源生长量最大,这与其生长势强是一致的。从不同种源间的阴香主要表型性状生长量分析,叶宽生长量以赣州种源最大,呈显著性差异。叶长生长量以韶关种源增长量最大,且有显著性差异。韶关种源生长量和生长势均最强。根据生物学表型性状指标对8个种源地的阴香进行聚类分析,表明其表型性状相似性与地理位置有一定的相关性。研究结果将为阴香资源保护与利用提供相关表型性状的指标量化基础数据。

Abstract: This study investigated the phenotypic characteristics and diversity of Cinnamomum burmannii plants from various provenances across the country. Eight provenances were selected as test materials, and twenty-two biological phenotypic traits, including crown shape, leaf structure, branch formation, and plant height, were measured. Phenotypic variations were analyzed through correlation and difference analysis. The results indicated significant differences among the twenty-two biological phenotypic traits, particularly in plant height, ground diameter, petiole length, and leaf length. Notably, the provenances from Shaoguan and Jian'ou exhibited the highest growth increments, which aligns with their strong growth potential. Furthermore, the analysis of the primary phenotypic trait growth increments across different provenances revealed that the Gangzhou provenance showed the largest growth increment in leaf width, demonstrating significant variation. The Shaoguan provenance recorded the highest growth increment in leaf length, again with significant differences noted. Overall, the growth increment and potential of the Shaoguan provenance were found to be the most pronounced. Additionally, cluster analysis of C. burmannii from the eight provenances, based on biological phenotypic trait indicators, suggested that the similarity of phenotypic traits was somewhat correlated with geographical location. The findings of this research will provide quantitative baseline data on relevant phenotypic traits, contributing to the conservation and utilization of C. burmannii resources.
