Systemic acquired resistance induced in cucumber plants against powdery mildew disease by pre-inoculation with tobacco necrosis virus
Systemic Acquired Resistance (SAR) in cucumber plants against powdery mildew disease, caused by Sphaerotheca fuliginea (Schlechtend Fr.) Pollacci, was induced by localized infection in cucumber cotyledons with Tobacco Necrosis Virus (TNV). Inoculation of the two cotyledon leaves significantly reduced powdery mildew severity on cucumber true leaves similar to the effect of fungicide. TNV-local lesions developed plants still protected against powdery ... إقراء المزيد
