Abstract
|
|
|
Dry weight, and mineral content in leaves, stems, and roots of the ginseng plant (Panax ginseng C.A. Meyer) were investigated. The highest T/R ratio, 0.52, was observed in a four year old plant due to a vigorous growth of the plant at this age. Also the dry weight increase was rather higher in the younger root than the older one.
Mineral content of the plant was rather higher in the younger root than the older one. Potassium content in leaves and stems was higher than those of nitrogen and phosphorus. Generally, the leaves contained more iron and manganese than any other micronutrients. The iron content amounted to 1,000∼2,000ppm in leaves. Zinc content was higher in stems and leaves than roots especially in stems of the younger roots.
Total amount of the up-taken N, P₂O_5, and K₂O per 10a in six years was 10.2㎏, 2. 3㎏ and 14.9㎏ respectively, indicating the considerable abounts of K₂O was absorbed.
