Use of calcium to delay ripening of tomatoes

Resumo

O amadurecimento foi retardado pela infiltração a vácuo de frutos verdes cv. Rouge de Marmande com soluções de CaCl2. O amadurecimento foi inibido em frutos tratados com 8-12% de CaCl2 a 500-550 mm Hg. O conteúdo normal de Ca de 11 mg/100 g de peso fresco teve que ser aumentado para 40 mg/100 g de peso fresco para que o amadurecimento fosse apreciavelmente retardado.



Abstract

Ripening was delayed by vacuum infiltrating green cv. Rouge de Marmande fruits with CaCl2 solutions. Ripening was inhibited in fruit treated with 8-12% CaCl2 at 500-550 mm Hg. The normal Ca content of 11 mg/100 g fresh weight had to be increased to 40 mg/100 g fresh weight for ripening to be appreciably delayed.
