Table 1.
The effect of (A) 2,4-D, (B) NAA and (C) NAA and TDZ on adventitious root formation from callus of Panax ginseng. Data evaluation in all the experiments was according to analysis of variance (ANOVA), and the significant differences among the treatments were compared using the Duncan's multiple range test (DMRT) with a 0.05 level of probability [28].
