Abstract
Effects of ultraviolet(UV) irradiation,mutagenic agents ethylmethane sulphonate(EMS) and sodium azide(NaN3) on plant regeneration of cotyledons in two Brassica napus cultivars(Zheshuang 758 and Zheshuang 6) in vitro were investigated.Results showed that UV had some promoting effects on cotyledon regenerations.The highest rates of callus induction and plant regeneration were observed from the two cultivars when treated with UV for 120 s and 60 s,respectively.EMS at different concentrations significantly affected the numbers of shoot explants and plant regeneration,and there was interactive effect between EMS concentrations and treatment times.When EMS concentration was 20 mg/L and treatment time was 6 h,the highest numbers of shoot explants and plant regeneration were reached.There were significant differences in numbers of regenerated plants between different treatment concentrations of NaN3(500 μmol/L or 100 μmol/L)and between different treatment times(5 h or 24 h).No obvious interactive effect was found among different treatment factors.
