摘要：

针对目前国内多花黄精种茎无标准和用种不规范的现状,研究多花黄精种茎规格、年龄对产量及药用品质的影响,旨在为多花黄精科学选种用种提供理论依据。采用双因素随机区组设计,主因素为规格,副因素为年龄,以多花黄精种茎的芽头数、茎长、茎径和茎质量为指标,采用K-means聚类法将种茎分成3个规格、3个年龄,通过调查出苗率、单株产量、单位面积产量和块茎多糖含量变化情况,分析不同规格、年龄种茎处理下2年生多花黄精产量和药用品质的差异。种茎规格、年龄与出苗率相关;种茎规格与单株产量、单位面积产量极显著相关,种茎年龄与单株产量、单位面积产量显著相关;种茎规格与多糖含量极显著相关,种茎年龄与多糖含量显著相关。推测种茎规格与年龄存在交互作用,高规格、低龄多花黄精种茎适宜作种,能显著提高多花黄精药材产量和药用品质。

Abstract:

In view of the current situation of no standard and improper use of Polygonatum cyrtonema’s stem tuber in China, the effects of stem size and age on yield and medicinal quality of P. cyrtonema were studied, aiming to provide a theoretical basis for seed selection and use of P. cyrtonema. A two-factor randomized block design was conducted with stem size as the main factor and age as the other factor. P. cyrtonema’s stem tuber number of shoots, length, diameter, and weight were used as indicators, and the K-means clustering method was adopted to divide the stem tuber into 3 specifications and 3 ages. By investigating the changes in seedling emergence rate, yield per plant, yield per unit area, and tuber polysaccharide content, we analyzed the differences of yield and medicinal quality of two-year-old P. cyrtonema’s under different stem tuber sizes and ages. The results show that the stem tuber size and age are correlated with seedling emergence rate; the stem size is extremely and significantly correlated with yield per plant and yield per unit area; the stem age is significantly correlated with yield per plant and yield per unit area; the stem size is extremely and significantly correlated with polysaccharide content; and the stem age is correlated significantly with polysaccharide content. It is speculated that there is an interaction between the stem size and age, and stem tuber with high specification and low age is suitable for planting, which could significantly improve the yield and medicinal quality of P. cyrtonema.

Key words: K-means clustering method, Polygonatum cyrtonema, size of stem tuber, age of stem tuber, yield, medicinal quality
