Abstract
|
|
|
|
This study was carried out to investigate the correlation between root diameter and ginsenoside composition of Panax ginseng C. A. Meyer cultivar Yunpoong. Dry matter ratio of main root was a little higher than that of lateral root and fine root, and that was higher by the increase of root diameter in the same root parts. Total ginsenosides composition of main and lateral roots increased by the decrease of root diameter, especially in lateral root. Similar resulted in fine root, but there was no significant difference where root diameter was below 2.5 ㎜. Except for ginsenoside-Rg1, other ginsenosides component, PDs, PTs and total ginsenosides had highly negative correlation with the root diameter within whole root, main root+lateral root and lateral root+fine root, while Rg1 had positive correlation with the root diameter.
