百合属(Lillium spp。)植物种质资源丰富，兼具观赏、食用、药用价值，但品种选育与应用研究大多聚焦于观赏百合，而食用百合品种长期较单一，对于百合的多功能性研究也较缺失。该研究以 10 个 LA 百合品种为材料，进行观赏性状(花期、花色、株高、花苞数)和产量性状(母鳞茎鲜重增量、母鳞茎直径增量、小鳞茎数量、小鳞茎鲜重)，以及抗病性的综合评价研究，为开发赏食兼用型多功能百合提供理论基础。主成分分析结果显示，帝王黄、红妆和蜜苏卡综合得分位列前三;聚类分析将 10 个 LA 百合品种分为 3 类，与主成分分析结果基本一致，证实主成分分析的可信度。进一步选择综合评价最高的百合品种帝王黄鳞茎，测定其矿质养分、蛋白质、氨基酸、淀粉和粗纤维等营养成分含量，与江浙地区主产食用百合卷丹相比，总体营养价值相仿。因此，帝王黄等 LA百合品种具有赏食兼用潜力。
Evaluation of ornamental and edible LA lily cultivars based on principal component and cluster analyses
Lilies(Lillium spp.)are rich in species,with ornamental,edible and medicinal values,but most of the research on cultivar selection and application focuses on ornamental lilies,while edible lily cultivars have been relatively homogeneous,and the research on the multifunctionality of lilies is also limited.In this experiment,10 LA lily cultivars were used as materials for the study of ornamental characteristics(flowering period,flower color,plant height,and number of buds),disease resistance,and yield traits(incremental fresh weight of bulb,incremental diameter of bulb,number of bulblets,and fresh weight of bulblets),and comprehensive evaluation and screening were carried out,providing theoretical bases for the development of the multifunctional lily with both ornamental and dietary uses.The results of principal component analysis showed that Kingsville,Armandale and Sweet Sugar ranked in the top three in terms of comprehensive scores;cluster analysis classified the 10 LA lily cultivars into three categories,which was basically consistent with the results of principal component,confirming the credibility of the results of principal component analysis.Further,the lily cultivar Kingsville with the highest comprehensive evaluation was selected to determine its nutrient components such as mineral nutrients,proteins,amino acids,starch and crude fibers,and its overall nutrient value was similar when compared with that of edible lily Lillium lancifolium,which is the main production in Zhejiang.Therefore,Kingsville is a lily cultivar with the potential of being used for both ornamental and edible purposes.
