Correlation analysis between growth characteristics and ginsenoside contents of 4-year-old wild-simulated ginseng (Panax ginseng C.A. Meyer) with different cultivation sites

Abstract

The aim of this study was to investigate the correlation between growth characteristics and ginsenoside contents of 4year-old wild-simulated ginseng cultivated in different regions. Most of the soil properties except for available phosphate showed significantly higher in Pyeongchang than in other cultivation sites. The growth characteristics except for root length and number of rootlets showed significantly higher in Pyeongchang than in other cultivation sites. In the case of 8 ginsenoside contents, the content of F2-AS was significantly higher in Muju than in other cultivation sites and the content of F1 in Yeongju was significantly high. In Yeongwol, the contents of Rb1 and Re-p were significantly high and the content of Ro in Pyeongchang showed significantly higher than in other cultivation sites. Root length and soil pH did not show a significant correlation with any soil properties and growth characteristics of wild-simulated ginseng, respectively. Most of the growth characteristics showed significantly positive correlations with electrical conductivity, organic matter content, total nitrogen content, exchangeable cations (K + , Ca 2+ , Mg 2+ ), and cation exchange capacity. Rb1 and Re-p showed significantly negative correlations with most of the growth characteristics of wildsimulated ginseng except for the number of rootlets. Ro showed a significantly positive correlation with stem length, number of leaflets per stem, leaflet length, leaflet width, and root diameter. The results of this study probably will help to provide useful information on the establish a quality standard by investigate correlation analysis between growth characteristics and ginsenoside content of 4-year-old wild-simulated ginseng.

Relationships between Rhizosphere Environments and Growth of 10-Year-Old Wild-Simulated Ginseng

“…Various studies have been mainly conducted on 7-year-old and 13-year-old WSG. One study has reported correlations between growth and ginsenosides of 4-year-old WSG [19]. However, no such study has been conducted on 10-year-old WSG.…”
