| ABSTRACT This study aimed to investigate the effect of silicon (Si) sources and doses on the physicochemical quality as well as post-harvest conservation of tomato fruits. Treatments were arranged in a 3 x 5 factorial scheme corresponding to sources {calcium silicate, potassium silicate and sodium silicate} and five doses of Si (equivalent to 0, 100, 200, 400 and 800 kg/ha SiO2). Randomized blocks were the experimental design, with four replications. Soluble solids, vitamin C, lycopene, titratable acidity, mature fruit firmness, initial firmness, firmness half-life, time until reaching firmness equivalent to 3.0 x 104 N/m2 and 2.0 x 104 N/m2 and Si content in fruits were evaluated. Soluble solids, vitamin C and lycopene of fruits increased with increasing... |
