Effect of continuous low temperature on resistance of rice to rice blast caused by Pyricularia grisea



Effect of continuous low temperature on resistance of rice to rice blast caused by Pyricularia grisea



Acta Phytophylacica Sinica 26(2): 97-102



The effect of low temp. (<=20 degrees C) on resistance to Pyricularia grisea was evaluated using 2 rice cultivars, Shanyou duoxi1 (resistant) and Shanyou 63 (susceptible). Compared with an untreated control, lesions appeared 2 to 3 days earlier following exposure to low temperature, and the rate of infection increased after 3-5 d at low temperature but did not increase after longer exposure (>7 d).
