Abstract: Two contrasting varieties of tomato (Solanum lycopersicon L.) fruits i.e. 'Pusa Gaurav' (slow ripening type) and 'Pusa Ruby' (fast ripening type) were examined for Ca, P, K, Zn, Cu and Mn contents in the fruit's pericarp portion. Fruits were examined either at different ripening stages during their maturation on the plant itself or at different intervals during storage when harvested at green mature stage. Ca was found to be higher in 'Pusa Ruby'. 'Pusa Gaurav', on the other hand, showed higher content of P, Zn, Cu, Mn but low K in comparison to 'Pusa Ruby'. The roles of these minerals were explained towards their stabilizing effect on plasma membrane and cell wall along with their involvement in the antioxidative system and thereby determining the rate of ripening.
