Response of Korean ginseng (Panax ginseng C. A. Meyer) to 2, 4-D I . Effects of 2, 4-D concentrations on Growth and Root Yield
제초제 2, 4-D에 대한 고려인삼의 반응 I. 2, 4-D의 농도가 인삼의 생육 및 근수량이 미치는 영향
Abstract
Weeds may compete detrimentally with the ginseng for moisture and nutrients but hand weeding is the only practical means of eliminating weeds after crop establishment. To define the effects of 2, 4-D herbicide application on the plant growth and root yield of Korean ginseng (Panax ginseng C. A. Meyer). the herbicide 2, 4-D was applied as a foliar spray with the rates of 0.5. 1.0. 1.5 and 2.0 times of the recommended herbicide dosage 70ml/l0a. The Korean ginseng treated with 2, 4-D in the rate of two times concentration was indistinguishable from nontreated plants in visual rating for foliar symptoms. There were no significant differences of the leaf length and width as well as the stem length and diameter in check plants and those recieving 2, 4-D treatments. The. berry maturing in 3 and 4-years old ginseng was not inhibited with 2, 4-D treatment. The root weight of the 4-years old ginseng plant was not reduced by 2, 4-D application of 2 times dosage. However. when the ginseng seedling was treated with 2, 4-D. detrimental phenomena as stem bending and dicoloration of marginal part of seedling leaf were occured but stem bending was recovered in a few days.
