Physiological and biochemical changes in plants exposed to high temperatures may lower
their resistance to diseases. In this regard, this study investigated whether thermal
oscillations could change wheat resistance to blast, caused by Pyricularia oryzae,
considered one of the most important diseases affecting wheat production. Plants were kept
in two growth chambers with temperatures of 19 and 28° C each for five days for thermal
acclimatization and inoculated with P. oryzae after that. After inoculation, groups of plants …
