Eliciting plant defense on anthracnose disease in chili (Capsicum annuum Linn.) by sodium nitroprusside solution

The study on the induction of plant defense against to anthracnose disease of chili by sodium nitroprusside solution was investigated during pre- and post-harvest. Pre-harvest treatment was conducted by spraying the chili plants with sodium nitroprusside (SNP, nitric oxide donor) solution at 0 (control), 0.05 and 0.1 mM every 3 days for 9 times before inoculating with the spore suspension of Colletotrichum gloeosporioides (the causal agent of anthracnose disease) and then sprayed with SNP again 1 time after inoculating.
