不同种源阴香的表型性状多样性分析
Diversity Analysis of Phenotypic Traits of Cinnamomum burmannii from Different Provenances in China
摘要
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.关键词
