“…However, Li (1997) also reported that roots were shorter in loamy sand than in sandy loam soils despite the higher sand content and suggested that the effect of soil particle size could be confounded by other factors. It is likely that soil with a small particle size has more moisture (Saxton and Rawls, 2006); therefore, poor drainage may decrease root weight (Lee et al, 2012). High soil moisture suppresses ginsenoside production in P. ginseng (Lee et al, 2012).…”

We aimed to evaluate the effects of abiotic factors on root growth and ginsenoside content of Panax ginseng and on the tradeoff between these two properties. Three experiments tested the effects of fertilization, soil particle size and cultivation site, respectively, on root growth and ginsenoside content. Moderate applications of nitrogen, phosphorus, and potassium did not significantly influence ginsenoside content. Root weight was negatively correlated with ginsenosides Rg1 and Rg2 with excessive fertilization, suggesting that environmental stress caused by excessive fertilization might have created a tradeoff. We tested the effect of soil type by separating soil out according to particle size (ie, < 0.5, 0.5-1 and 1-2 mm, and a mixed control). Root weight was lower in soil of < 0.5 mm, and roots were longer in soil of 1-2 mm compared with those of the control. Total ginsenoside and ginsenoside Rb 1 content was lower in soil of < 0.5 mm than those of the unsieved control. These results indicate that soil texture is an important factor determining ginsenoside yield and root quality. The effect of cultivation site was compared among 5 locations using the same soil type. There was a 2.8-fold difference in root weight and a 2.1-fold difference in total ginsenoside content between the highest and lowest values among 5 sites, and no significant correlation was found between root growth and ginsenoside content. Our results suggest that ginsenoside content was influenced by abiotic stresses caused by changes in nutrient, moisture, and temperature. We conclude that proper management of abiotic stresses can promote both root growth and ginsenoside content without a tradeoff between these two properties.

“…There has been growing interest in developing cultural methods to control both root mass yield and ginsenoside content (Park et al, 1986;Lee et al, 2012). However, there is little information on the effects of soil quality and climate on the cultivation of P. ginseng.…”

: To study the cause of physiological disorder in leaf of ginseng cultivated at paddy soil, the degree of browncolored symptom (BCS) and the contents of inorganic matter in leaf were investigated by irrigating the solution of ferric and ferrous iron of 0.1~2.0%, and citric acid of 1.0~4.0% on bed soil, respectively. Ratio of BCS by variety was as high as 85.0% in Yoenpoong, while it was as low as 5.4%, 7.5% in Chunpoong and Hwangsook, respectively. The contents of inorganic matter of leaf in Yoenpoong were lower in P 2 O 5 , Ca, and Mg, while it were higher in K, Fe, and Mn than other variety. Iron solution caused BCS more distinctly when each ferric and ferrous iron were dissolved with 1.0% citric acid than when each iron was dissolved without citric acid. Ferric iron caused BCS more effectively than ferrous iron. BCS occurred in 4.0% citric acid was as same as 2.0% ferric iron mixed with 1.0% citric acid. Low P 2 O 5 and high Fe content in leaf appeared in both of artificial and natural symptoms. We concluded that excessive Fe uptake caused BCS to leaf because the solubility of iron was increased in condition of low soil pH.

: This study was carried out to investigate the cause of leaf discoloration occurring frequently in paddy cultivation. Chemical property of soil and inorganic nutrient component of leaf were analyzed on abnormal fields of 7 regions where leaf discoloration occurred severely and normal fields of 7 regions among ginseng garden. The pH of abnormal fields was strong acidic condition (pH 5.51) compare to normal fields of slightly acid condition (pH 6.42). Calcium and magnesium content in abnormal fields were lower distinctly than that of normal fields, while EC, organic matter, phosphate, and potassium content showed not distinct difference between abnormal and normal fields. Whereas calcium and magnesium content were distinctly high in normal fields, both of potassium and iron content of ginseng leaf were distinctly high in abnormal fields. In particular, iron content of abnormal fields was more 1.94 times in soil, and 3.03 times in leaf than that of normal fields. In soil chemical property, there were significant negative correlation between leaf discoloration ratio and soil pH, and there were also significant positive correlation between leaf discoloration ratio and iron content. In ginseng leaf, there were highly significant negative correlation between leaf discoloration ratio and calcium content, and there were also highly significant positive correlation between leaf discoloration ratio and iron content.
