Abstract: Local and systemic resistance to anthracnose of Camelia oleifera was induced when the plant was sprayed by salicylic acid solutions.The inducing effect was the strongest when the concentration of salicylic acid was 150 mg·L-1,exhibiting 54.15% and 61.55% anthracnose inhibition rates on younger and elder leaves respectvively by local induction,and up to 46.7% inhibition rate by systemic induction.The maximum control rate of 45.32% was also attained in field experiment.The level of local induced resistance by salicylic acid had maintained 20 d without declining evidently.Under scanning electron microscope,the conidia germinated,but the growth of germ tubes was inhibited,and even malformed or twisted.
