Conteúdo:

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 doses of Si, except for the highest dose. Calcium
and sodium silicate provided the highest lycopene concentration in
fruits. An increase in initial firmness, number of days until reaching
firmness half-life and firmness equivalent to 3.0 and 2.0 x 104 N/m2
were observed along with increasing doses of Si. Tomato fertilization
with calcium silicate, potassium silicate and sodium silicate, used as
sources of Si, increased the post-harvest conservation as well as the
physicochemical quality of tomato.
