ABSTRACT

The activities of Polygalaturonase (PG), Polymethylgalacturonase (PMG) and Cellulolytic enzymes (CX) were higher in ripe fruits (36.47, 34.69 & 30.75%) inoculated with F. pallidoroseum, respectively. The enzymatic activity of PG, PMG and CX were found increased with time. Tomato fruits inoculated with F. pallidoroseum showed decrease in total soluble sugar (2.04 %), ascorbic acid content (12.36 mg/100g), acidity (0.48 %) content and physiological weight loss (35.15 g) (50.21%) as compared to uninoculated fruits.
