There was consistent increase in the activities of defense related enzymes such as catalase, peroxidase, polyphenol oxidase, superoxide dismutase and phenylalanine ammonia lyase and other defense related secondary metabolites like phenols and flavonoids at different phases of black spot progression and increase was high in resistant genotypes Knock Out and Arka Nishkant. The peak activity of defense enzymes and high concentration of other metabolites was witnessed during early stages of infection in the resistant genotypes while it was during later phase in the susceptible genotypes. These results suggested that the faster and stronger activation of defense system is associated with the resistance against black spot in the rose genotypes. 2022 artículo científico 0973-354X https://www.redalyc.org/articulo.oa?id=577073671024 https://www.redalyc.org/journal/5770/577073671024/ https://www.redalyc.org/journal/5770/577073671024/html/ https://www.redalyc.org/journal/5770/577073671024/577073671024.epub https://www.redalyc.org/journal/5770/577073671024/movil https://doi.org/10.24154/jhs.v17i1.1027 en http://www.redalyc.org/revista.oa?id=5770 Journal of Horticultural Sciences application/pdf Society for Promotion of Horticulture Journal of Horticultural Sciences (India) Num.1 Vol.17 |
