摘　　要：以收集的30份怀山药种栽为研究材料,采用K均值聚类法划分种栽等级,制定分级标准;在此基础上,研究不同等级种栽与出苗率、生长、品质及产量的关系.结果表明:所收集的怀山药种栽可分为3个等级,分级指标与怀山药种栽质量等级划分的相关程度依次为:百根质量>围径>饱满度>净度>长度;种栽质量等级与出苗率、生长、产量及品质等相关指标均呈正相关,可作为怀山药种栽的质量控制参考标准,建议生产上选用一、二级种栽.Thirty batches of seed stocks from different plots of the different towns or the same town in the Jiaozuo city of Henan province were taken as experimental materials？ which were analyzed through K-center clustering to establish the quality grading standard. On this basis, we studied the relationship of seedling emergence, growth, quality and yield to the quality grade. The results showed that ：seed stock can be divided into three levels. The correlation degree between classification inde-xes and quality grade was in the following order： one hundred weight〉encircles diameter 〉plumpness〉purity〉length; The studies indicated that the quality grade of seed stock was probably correlated with seedling emergence, growth, quality and yield. This classification standard can be used as reference standard to quality control of Dioscorea opposita Thunb. The Grade 1 and Grade 2 are suggested to be used in the production.
