摘　　要：为建立傣百解种苗质量分级标准,观察并测量2月龄傣百解种苗的苗高、地径、叶数、叶宽、叶长、根粗、根长等指标,经过相关性分析和主成分分析确定种苗分级指标,采用K-均值聚类分析进行分级研究。结果表明,傣百解种苗分为3个等级:Ⅰ级标准为苗高≥37.00 cm,地径≥4.00 mm,根长≥15.00 cm,根粗≥3.80 mm;Ⅱ级标准为24.00 cm≤苗高<37.00 cm,3.30 mm≤地径<4.00 mm,12.00 cm≤根长<15.00 cm,3.00 mm≤根粗<3.80 mm;Ⅲ级标准为13.00 cm≤苗高<24.00 cm,3.00 mm≤地径<3.30 mm,6.00 cm≤根长<12.00 cm,2.50 mm≤根粗<3.00 mm。To establish the quality grading standard of Marsdenia tenacissima seedlings,Seedling height,ground diameter,leaf number,leaf width,leaf length,root diameter and root length of 2-month-old seedlings were observed and measured.The seedling grading indexes were determined by correlation analysis and principal component analysis,and k-mean clustering analysis was used for grading study.The results showed that the Marsdenia tenacissima seedlings were divided into three grades:gradeⅠ:seedling height≥37.00 cm,ground diameter≥4.00 mm,root length≥15.00 cm,root diameter≥3.80 mm;GradeⅡ:24.00 cm≤seedling height<37.00 cm,3.30 mm≤ground diameter<4.00 mm,12.00 cm≤root length<15.00 cm,3.00 mm≤root diameter<3.80 mm;GradeⅢ:13.00 cm≤seedling height<24.00 cm,3.00 mm≤ground diameter<3.30 mm,6.00 cm≤root length<12.00 cm,2.50 mm≤root diameter<3.00 mm.
