Abstract:
A series of experiments were conducted to study the mutation of Kloechera apiculata by many kinds of treatments such as UV and UV+LiCl.The optimal dosage disposal was determined:15 W 30 cm under Ultraviolet irradiation for 20 s,UV+LiCl under Ultraviolet irradiation for 20 s and added LiCl 0.3% (w/v).One strain(UV20-13)which had obvious physiological characteristic was obtained.the incidence of blue and green mold of citrus was reduced by 25.56%and 10.00%in vivo experiment after 7 days respectively. The strain UV20-13 was tested by the experiments of subculture and dynamic growth,and the results showed that the strain UV20-13 was better than K.apiculata in the growth characteristics,and it did not appear retrogression,reversion mutation ect after subculturing 10 generations.Therefore the strain UV20-13 had genetic stability.
