Abstract

Growth of the plant pathogenic fungus Rhizoctonia solani Kuhn, which is the causative agent of one of the most harmful and widespread potato diseases (black scab), has been experimentally studied. Sclerotia of Rhizoctonia solani are irradiated with accelerated electrons with an energy of 1 MeV at various doses in the range from 0.02 to 38 kGy. The results of the study made it possible to conclude that the exposure to electrons in the dose range both inhibited and stimulated the growth of R. solani plant pathogenic fungi; the dependence of the growth rate of R. solani fungi on the absorbed dose is not linear. Germination of R. solani sclerotia was completely suppressed when the absorbed dose was more than 4.5 kGy.

电离辐射对茄枯病菌致病菌生长的影响

摘要

已经对植物致病真菌Rhizoctonia solani Kuhn的生长进行了实验研究，Rhizoctonia solani Kuhn是最有害和最广泛的马铃薯疾病（黑sc）之一的病原体。在0.02至38 kGy范围内的各种剂量下，用1 MeV能量的加速电子辐照茄根核裂菌菌核。研究结果可以得出结论，暴露于剂量范围内的电子既抑制又刺激了茄sol病原菌的生长。茄根真菌生长速率对吸收剂量的依赖性不是线性的。solani的发芽 当吸收剂量大于4.5 kGy时，菌核被完全抑制。
