摘要(Abstract):

目的:制定黄连种苗质量分级标准。方法:测量19个不同产地黄连种苗的株高、叶片数、叶长、叶宽、叶重及根重等指标,通过对各指标数据的相关性统计分析,并结合生产实际,确定黄连种苗质量分级的主要指标和参考指标。采用动态聚类确定黄连种苗的质量分级标准。结果:叶数是黄连种苗质量分级的主要指标,株高作为质量分级的低优指标。结论:黄连种苗分为3级,Ⅰ级种苗:叶数≥8片,14≥株高≥12 cm;Ⅱ级种苗:8≥叶数≥6,12 cm≥株高≥9 cm;Ⅲ级种苗:6≥叶数≥4,株高≥9 cm;达不到3级种苗标准的为不合格种苗。
Objective: To establish seedling classification criteria of Coptis chinensis.Method: The height of plant,leaf number,leaf length,leaf wide,weight of leaf,weight of root were measured,the main measurement indexes of seedlings of C.chinensis were chosen through correlation and regression analysis.The seedling classification criteria were formulated by dynamic clustering analysis.Result: The criteria of the l st-grade seedlings were as follows: leaf number above 8 leaves,height of plant between 12 and 14 cm.The criteria of the 2nd-grade seedlings were as follows: leaf number between 6 and 8 cm,height of plant between 9 and 12 cm.The criteria of the 3rd-grade seedlings were as follows: leaf number between 4 and 6 cm,height of plant above 9 cm.Conclusion: The seedling classification criteria of C.chinensis was scientific and feasible,and can be used for the quality control standard of C.chinensis.
