Özet

This study was conducted to investigate the effects of salt stress on germination of four silage maize (Zea mays L.) cultivars (Ozgem, Efe, Safak and Side). The degree of salinity tolerance among these cultivars was evaluated at seed germination stage at four different salt concentrations (0, 4, 8 and 12 dS m(-1) NaCl). The germination percentage, salt tolerance index, shoot dry weight, root dry weight were determined in this research The results showed that in all cultivars as the salt concentration increased, germination percentage decreased significantly. Responses of cultivars to salt stress indicated differences. Cultivar Efe had the highest germination percentage. The highest shoot dry weight was obtained from cultivar Efe while the lowest shoot dry weight was obtained from cultivar Ozgem. Salt concentration decreased shoot and root dry weight. Efe and Safak had the highest root dry weight. The results showed that Efe is the cultivar to be recommended for saline soils.
