Localization of Metabolites and Enzymes in post harvested fresh and infected Apple and Guava fruits

Apple and Guava are an important fruit crops grown commercially in different agro climatic conditions of India for its diversified use. These fruits were respectively post harvested affected by Monilinia and Rhizoctonia solani fungi. Investigation was made on histochemical localization of different metabolites, like starch, insoluble polysaccharides, protein, peroxidase, acid phosphatase and polyphenoloxidase of fresh and infected apple and guava fruits. The purpose of the present investigation was to study the possible alteration in metabolic activity on affected fruits due to pathogens. Starch, insoluble polysaccharide and protein were observe in enhance quantity in fresh fruits as compare to infected fruits but relatively higher amount of enzymes were detected in the infected tissues, suggested altered metabolism of the host tissue due to pathogenesis.
