Biochemical alterations in healthy and infected stem bark of mango genotypes infected by black banded disease

Abstract

In this study, the level of total sugars, total phenols and total alkaloids were studied in the healthy and infected stem bark of six genotypes. Biochemical analysis of healthy and infected bark of mango showed that there was considerable decrease in the reducing sugar, non-reducing sugar, total sugars and total alkaloids content of infected bark. While phenol content of the infected bark showed considerable increase as compared to the healthy bark. In the present study, the contents of total sugars, reducing sugars and non-reducing sugars were higher in healthy bark of all the genotypes and decreased in infected bark.
