| Abstract: | In this paper,the mutagenic effect of HeNe laser,Nd:YAG frequency doubling pulse laser and UV on abscisic acid(ABA) producing strain was compared.In UV induced mutants,3.84% has increased potency,76 9% has decreased potency,while in HeNe laser and Nd:YAG frequency doubling pulse laser irradiation strains the positive mutant rate was 5.6% and 19.6%,respectively.It was presented that after ABAproducing strains were irradiated with Nd:YAG frequency doubling pulse laser for 400 times,strains with high yield over 60% than that of control strains were obtained. |
