Abstract

Seeds of two tomato varieties INCA-17 and INCA 9(1) were germinated under different saline concentrations of sodium chloride (0, 50, 100, 150 mM). Germination percentage, germination dynamics and fresh and dry weight production were determined. Imbibition water was recorded 24 hours after being placed in different saline solutions. Germination percentage was significantly inhibited when saline concentrations increased; this was more pronounced in INCA-17 cultivar. Germination dynamics was modified in each cultivar, their maximum germination rate
experimenting a displacement in time. Fresh and dry biomass
production was influenced by saline concentration increment,
INCA-17 cultivar being stimulated by saline concentration of 50 mM. However, INCA 9(1) biomass production was not inhibited with increase of saline concentrations. Imbibition water was not modified by salinity, so that it was not responsable of germination inhibition.
