초록

To study the cause of physiological disorder in leaf of ginseng cultivated at paddy soil, the degree of brown-colored symptom (BCS) and the contents of inorganic matter in leaf were investigated by irrigating the solution of ferric andferrous 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 as85.0% in Yoenpoong, while it was as low as 5.4%, 7.5% in Chunpoong and Hwangsook, respectively. The contents ofinorganic matter of leaf in Yoenpoong were lower in P₂O5, Ca, and Mg, while it were higher in K, Fe, and Mn than othervariety. Iron solution caused BCS more distinctly when each ferric and ferrous iron were dissolved with 1.0% citric acidthan when each iron was dissolved without citric acid. Ferric iron caused BCS more effectively than ferrous iron. BCSoccurred in 4.0% citric acid was as same as 2.0% ferric iron mixed with 1.0% citric acid. Low P₂O5 and high Fe content inleaf appeared in both of artificial and natural symptoms. We concluded that excessive Fe uptake caused BCS to leaf becausethe solubility of iron was increased in condition of low soil pH.
