Biochemical Factors Imparting Resistance to Leaf Blight of Barley

Overall the resistant genotypes of barley recorded higher amount of total phenol, total protein, sugars, chlorophyll content as compared to genotypes susceptible to leaf blight disease. The amount of these biochemical components increased from 30 days after sowing (DAS) to 60 days after sowing (DAS). However, healthy counterparts of plant samples recorded higher biochemical content (total phenol, total protein, sugars, chlorophyll content) as compared to inoculated counterparts at both the stages. The study revealed that higher sugars, phenols, proteins, chlorophyll contents are some of the possible reasons for resistance to leaf blight disease in barley.
