Characteristics of the Resistant Mutants of Sclerotinia sclerotiorum to Iporodione by Ultraviolet Rays
摘要
Abstract
In the laboratory, by ultra-violet rays, the iprodione-resistant mutants of Sclerotinia sclerotiorum were induced, and the resistances of iprodione-resistant mutants were tested by rate of mycelia growth. The results showed that the EC50 values of iprodione of all iprodione-resistant mutants ranged from 0. 1159 μg/mL to 604. 2200 μg/mL, with the average of 117. 1363 μg/mL. The EC50 of UVIPrSS-7 , UVIPrSS-8 , UVIPrSS-15 , UVIPrSS-16, and UVIPrSS-18 were higher than 160 μg/mL. Sclerotial numbers and weights of the mutants, which cultured in PSA medium with iprodione of 1 μg/mL, were more than control with no iprodione. It suggested that in this experiment, the iprodione-resistant strains were easily obtained and there might be resistance risk of iprodione.关键词
