Abstract
Effects of UV-B radiation and Magnaporthe grisea on growth and blast of two rice (Oryza sativa L.) cultivars were studied by pot experiments. Two rice cultivars (Huangkenuo and Hexi-41) were treated by four enhanced UV-B radiation levels (0, 2.5, 5.0 and 7.5 kJ·m-2) and two blast isolates (Y98-16T and Y99-63C), whilst two blast isolates (Y98-16T and Y99-63C) were radiated by four enhanced UV-B radiation levels (0, 2.5, 5.0 and 7.5 kJ·m-2). Changes of plant height, biomass and disease index of rice, and growth rates of Magnaporthe grisea were determined. Experimental results were gotten. Comparing with inoculated two blast isolates, enhanced UV-B radiation 7 days and then inoculated two blast isolates could decrease disease index of two rice cultivars. Hexi-41 showed the largest decrease in disease index by 83.5% with the treatment of 2.5 kJ·m-2-Y98-16T. Blast disease in Hexi-41 was reduced. UV-B radiation might change morphology and physiology of rice, increase the capacity of rice for resisting blast. Comparing with inoculatedY98-16T, inoculated Y98-16T and then enhanced UV-B radiation increased disease index of two cultivars. The largest increase in disease index was 53.7% in Hexi-41 with the treatment of Y98-16T-7.5 kJ·m-2. Blast disease in Hexi-41 was exacerbated. In general, UV-B radiation increased the growth rates of Y98-16T directly. Comparing with inoculated Y99-63C, inoculated Y99-63C and then enhanced UV-B radiation, disease index of two rice cultivars was not changed. UV-B radiation had no effect on the growth rates of Y99-63C.
