Other claims from this paper (10)
- Intervention effect A 3:30 calcium to magnesium ratio produced calcium-deficit symptoms in tomato seedlings.
- Intervention effect At 3:30 Ca:Mg, seedling dry-weight increment and protein content decreased.
- Intervention effect At 3:30 Ca:Mg, nitrate reductase activity was inhibited.
- Intervention effect Doubling calcium to 6:30 reduced magnesium accumulation.
- Intervention effect Calcium accumulation remained unchanged with the doubled calcium dose.
- Intervention effect Nitrate reductase activity increased to near-control values with doubled calcium.
- Intervention effect Seedlings at 9:30 Ca:Mg did not differ from controls.
- Intervention effect Increasing calcium under high magnesium enhanced potassium accumulation.
- Mechanism Authors suggest greater potassium accumulation could affect nitrate absorption and reduction.
- Mechanism Authors suggest tissue calcium deficit induced by magnesium accumulation causes nitrate assimilation disorders.
