Abstract :
The study was carried out to determine the effects of different NaCl concentrations (0 control, 2, 4, 6, 8 and 10 dS m^-1) on seed germination and early seedling growth of silage corn cultivars (Burak, Efe, Hido, Safak). Eight seeds of each cultivar for each treatment were placed in a petri-dish having a diameter of 15 cm. While the germination rate was measured 5 days after sowing, root length (cm), shoot length (cm), wet root and shoot weight (mg) and dry root and shoot weight (mg) were measured 9 days after sowing. The study showed that cultivars had different responses to NaCl concentrations. It was determined that the germination rate and some seedling characteristics were reduced with increasing salinity level. The results revealed that salinity had significantly (p≤0.001) affected all the parameters studied. Maximum root length (14.6 cm), shoot length (6.8 cm), root fresh weight (365 mg plant^-1), shoot fresh weight (235.7 mg plant^-1), root dry weight (51.5 mg plant^-1), shoot dry weight (30.6 mg plant^-1) were recorded in Hido variety. Among the cultivars, Hido was the most tolerant cultivar, while Efe was the most sensitive.
