dc.description.abstract“Salicylic acid as an elicitor for the induction of systemic acquired resistance against fusarium wilt (Fusarium oxysporum f. sp. ciceri) in chickpea (Cicer arietinum L.)” Salicylic acid spray on healthy and inoculated chickpea plants revealed that activities of peroxidase, polyphenol oxidase and phenylalanine ammonia lyase remained higher at all infection stages in sprayed plants of both healthy and inoculated soil. In plants grown in inoculated soil during infection stage, activities of peroxidase, polyphenol oxidase and phenylalanine ammonia lyase remained higher in root tissues of sprayed plants. All the enzymes studied in leaf, stem and root tissue were higher in seedlings grown in inoculated soil as compared to seedlings grown in healthy soil. Basic protein banding pattern at pre infection stage, in leaf and root tissues of seedlings grown in inoculated soil showed the presence of one extra band in sprayed plants. In root tissue of sprayed plants at infection stage one extra band was appeared and which was not found in control plants. Stem tissue of control and sprayed plant showed no difference in the protein banding pattern at all infection stages. Acidic protein banding pattern at pre infection stage, in leaf and stem tissues from inoculated soil seedling showed 1 and 2 extra protein bands respectively in both control and sprayed plants. Leaf and root tissues from control and sprayed plants showed no difference in protein banding pattern at infection and post infection stage. Total phenol content increased in both seedlings grown in healthy and inoculated soil with growth of plant. In both healthy and inoculated soil sprayed plants showed higher total phenol content as compared to control plants. Study on phenol profile revealed that the leaf tissue showed higher level of all phenolics studied except salicylic acid. At infection stage (S3) umbelliferone, P-coumaric acid, chlorogenic acid, ferulic acid and venillic acid in leaf, umbelliferone, P-coumaric acid, chlorogenic acid, venillic acid and salicylic acid in stem and umbelliferone, catechol, chlorogenic acid, ferulic acid and salicylic acid in root of sprayed plants were higher than that of in tissues of control plants. Sprayed plants showed higher content of soluble protein as compared to control plants in both healthy and inoculated soil. Soluble proteins increased throughout all the stages except control leaf in healthy soil and root, stem and leaf tissues in inoculated soil from 10 DAS to 14 DAS. Study on total free amino acid revealed that in both healthy and inoculated soil, stem and root of sprayed plants had lower content of total amino acid as compared to control plants. Total free amino acid content decreased with plant growth stages in both healthy and inoculated soil. The intensity of disease was cent percent in control plants grown in inoculated soil while the intensity of disease reduced up to 40 % in sprayed plants up to pod formation stage. Some of the biochemicals studied have increased at infection stage in response to salicylic acid treatment might have restricted fungal growth in sprayed plants of highly susceptible variety. Further work is needed to confirm wilt resistance mechanism with salicylic acid treatment (by modified experimentation).en_US
