Abstract

Ripening inhibited (rin) tomato plants were grown in silicate sand and watered with half-strength Hoagland's solution until flowering. After flowering, plants were watered until run-off daily with full-strength Hoagland's solution containing 5 mM (control) or 1 mM calcium, or full- strength Hoagland's solution with 1.25 mM or 2.5 mM Na2EDTA. Fruit pericarp calcium levels were the same in Na2EDTA and control treatments at 90 days postpollination. The 1 mM Ca treatment significantly decreased total pericarp Ca levels compared to the control treatment. Sodium levels were higher in fruit from Na2EDTA-treated plants than controls. Fruit from control and 1 mM Ca treatments had significantly higher Zn than fruit from the Na2EDTA- treatments. None of the treatments induced increased ethylene production, redness, or increased soluble solids content of rin fruit.
