【摘要】 目的:对海南白沙县青松乡栽培的益智种质资源进行调查,对3个主要益智种质资源的外观形态和次生代谢产物含量进行评价,为益智优质种质资源选育提供基础。方法:测量益智不同种质资源叶片的长度和宽度,称量益智不同种质资源的果实粒重,用LC-MSMS分析不同种质资源果实中次生代谢产物的含量。结果:不同益智质资源的叶片长宽度、果实粒重和次生代谢产物含量间具有明显差异,以圆果益智的质量最佳。结论:益智不同种质资源的外观形态和次生代谢产物含量差异较大,圆果益智为优质品种,建议推广种植。更多还原

【Abstract】 Objective: To compare the morphological difference of three Aplinia oxyphylla Miq. cultivars,analyze the contents of secondary metabolites in three cultivars and then find the best cultivars. Methods: the length and width of leaf and fruit were measured, the fruit mass was weighed, and the contents of secondary metabolites was determined by LCMSMS. Results: The length and width of leaf and fruit,fruit mass and secondary metabolite were significantly different among three cultivars. Conclusion: The quality of round fruit A. oxyphylla was better than that of the other two cultivars.更多还原
