BIOCHEMICAL PROFILING OF CITRUS INFECTED WITH CITRUS GUMMOSIS DISEASE

Abstract

This research aims at the estimation of total soluble phenols, total soluble sugars, antioxidants and minerals i.e. zinc (Zn), iron (Fe) and manganese (Mn) in healthy and gummosis infected plant tissues. In this study, the mean of total soluble phenols were higher in healthy (6mg/ml and 3 mg/ml in leaves and bark, respectively) than infected plants tissues (2mg/ml and 1mg/ml in leaves and bark, respectively). The total soluble sugar in healthy plant tissue (5mg/ml, 3 mg/ml and 10 mg/ml in leaves, bark and fruits, respectively) was greater than in infected plants tissues (2mg/ml, 1 mg/ml and 3 mg/ml in leaves, bark and fruits, respectively). The antioxidant enzymes was present in higher quantity in infected plant tissues (43mg, 15mg and 50mg SOD, POD and CAT, respectively) than healthy plant tissues (35mg, 10mg and 40mg SOD, POD and CAT, respectively). The mineral elements significantly reduced in infected plants (51mg/kg, 48mg/kg and 30mg/kg Fe, Zn and Mn, respectively) as compared to healthy one (116mg/kg, 78mg/kg and 74mg/kg Fe, Zn and Mn, respectively). The biochemical characterization of gummosis disease would be helpful in sustainable disease management.
