Quantitative indexes of vegetation temperature effect on rice varieties susceptibility to Pyricularia

In the laboratory of artifical climate the dependence of the number of infectious spots on temperature of rice seedlings inoculation by blast pathogen has been studied experimentally. The regressive relationship of the number of spots and temperature, expressed by the function of Schrodter, has been...

Summary:In the laboratory of artifical climate the dependence of the number of infectious spots on temperature of rice seedlings inoculation by blast pathogen has been studied experimentally. The regressive relationship of the number of spots and temperature, expressed by the function of Schrodter, has been established. For one of the isolates of pathogen Pyricularia oryzae Cav. on 19 rice varieties the quantitative indexes characterizing the genetic pecularities of the fungus - plant interaction at different temperatures have been determined
