Title
Effect of manganese deficiency on fruit quality in tomato
B. K. Dube; C. Chatterjee Indian Journal of Horticulture 1999
Other claims from this paper (8)
- Intervention effect Manganese deficiency at 0.0011 mg Mn/litre reduced tomato fruit yield more than biomass.
- Intervention effect Low manganese decreased tomato leaf Mn, chlorophyll and starch concentrations.
- Intervention effect Low manganese decreased hill activity and acid phosphatase in tomato leaves.
- Intervention effect Low manganese significantly increased tomato leaf ribonuclease activity.
- Observation Visible manganese deficiency effects were pronounced on tomato middle leaves under acute deficiency at 0.0011 mg Mn/litre.
- Intervention effect Manganese deficiency significantly decreased ascorbic acid, soluble proteins and starch concentrations in tomato fruits.
- Intervention effect Manganese deficiency significantly decreased tomato fruit sugar concentration.
- Observation High phenols accompanied poor tomato fruit quality under manganese deficiency.
