Abstract
|
|
|
|
Uptake of phosphate, potassium, calcium and sodium ions by Korean ginseng (Panax ginseng C. A. Meyer) was investigated in excised roots. It was found that the uptake of these ions was mediated by dual or multiple patterns. In the range 0.009∼0.5mM, 0.10∼10.0mM, the uptake patterns of H_2PO_4^-, K^+, Ca^++, and Na^+ were described by 3, 2, 3, and 2 phases, respectively.
