Study on the Quality Grading Standard of Heracleum hemsleyanum Seedlings
摘要
Abstract
A total of 1791 seedlings of Heracleum hemsleyanum from 19 sites were collected and used as the experiment almaterials,and quality parameters such as root length,root diameter,number of lateral roots,bud length,number of budsandroot weight per plant seedling were determined.By using the K-mean clustering analysis combined with the actual production situation,grading of Heracleum hemsleyanum seedlings were performed.The results showed that Heracleum hemsleyanum seedlings could be divided into three grades according to root weight,root length and root diameter of the seedlings,i.e.,Grade Ⅰ:root weight≥16.0 g,root length≥22 cm and root diameter≥17 mm;Grade Ⅱ:8 g≤root weight<16 g,18 cm≤root length<22 cm,12 mm≤root diameter r<17 mm;GradeⅢ:3.6 g≤root weight<8 g,14 cm≤root length<18 cm,9 mm≤root diameter r<12 mm.关键词
