Abstract
To induct manganese-deficiency effects in tomato (Lycopersicon esculentum) var. Pusa Ruby, plants were grown in refined sand at two deficient i.e. 0.0011 and 0.055 mg/litre and one adequate, 0.55 mg/litre levels of manganese. Managese deficiency at 0.0011 mg Mn/litre reduced the fruit yield more than the biomass. At low manganese levels, the concentration of Mn, chlorophyll, starch, hill activity and acid phosphatase were decreased, whereas the concentration of sugars, activity of peroxidase, catalase and ribonuclease were increased significantly in tomato leaves. The visible effects of low manganese deficiency were pronounced on middle leaves under acute deficiency condition i.e. at 0.0011 mg Mn/litre. A significant decrease in the concentration of ascorbic acid, soluble proteins, starch, sugars and high phenols reflect poor quality of tomato fruits under manganese deficiency.
