Abstract:
Abiotic resistance inducers (ARI) are synthetic/natural compounds which induces innate resistance in plants against pathogens. Current study aimed to assess the foliar application of salicylic acid, potassium oxalate, β-amino butyric acid, sodium salicylate, and di-potassium phosphate @ 300ppm in managing bacterial blight of pomegranate in pot and field conditions. These inducers were assayed at 0, 2, 5, 10, and 14 days of pathogen inoculation. ARI treated plants recorded uttermost phenol and salicylic acid content accumulation at five days when challenged with pathogen. Similarly, activity of defense-related enzymes (phenylalanine ammonia-lyase, peroxidase, and polyphenol oxidase) was up regulated after challenge inoculation and it absolutely was most at fifth day. Interestingly, it was observed that regardless of sampling intervals, maximum content of biochemical parameters were perceived at fifth day followed by tenth day of pathogen inoculation. Our findings recommend that enhancing resistance in pomegranate plants before infection may be innovative, safe, and eco-friendly management strategy against bacterial blight of pomegranate.
