The effect of plant growth regulators and genotypes on callus and plant regeneration from in vitro culture of edible chrysanthemum petal was studied.The results showed that the efficiency of callus in the MS medium supplemented with 2,4-D 2.0 mg/L and KT 1.0 mg/L were better than others.The adventitious bud only could be induced from callus in the MS medium supplemented with NAA 0.5 mg/L and 6-BA 2.0 mg/L.The regenerated plants were obtained,after the adventitious buds were transferred to MS medium without ...
