Abstract:
Taking mature seed embryo of American Ginseng (Panax quinquefolium) as materials，using MS basal medium and MS+0.5 mg/L 2,4-D as controls，the effect of dicamba and salicylic acid (0.05-2.00 mg/L) on somatic embryogenesis of American Ginseng mature embryo was researched.The results showed that on MS basal medium without any hormones there were no callogenesis and embryogenesis；on MS+0.5 mg/L 2,4-D，the percentage of both attained to 100%；medium with five concentration of dicamba and salicylic acid all could induce somatic embryogenesis，in which the effect of 1.00 mg/L dicamba was the best，embryogenesis rate reached 56.60%，and the highest of salicylic acid was 7.5%；in salicylic acid，the growth volume of embryo was smaller than that of controls.The experiment showed that dicamba and salicylic acid could induce somatic embryogenesis on mature seed embryo of American Ginseng，induction capacity was 2,4-D>dicamba>salicylic acid；salicylic acid showed inhibitory effect on embryo growth.
