Two years of study on ten-year-old Kinnow mandarin revealed that the activity of hydrolytic enzymes namely protease, peroxidase and amylase increased in peel and juice tissues on tree, while polyphenol activity increased only in peel tissue and decreased in juice tissue during fruit maturation on tree. However, catalase showed increased activity in peel and juice tissues upto colour turning of fruit surface.
