Effects of Different Salt Concentrations on Germination and Seedling Growth of Some Sweet Sorghum [Sorghum bicolor var. saccharatum (L.) Mohlenbr.] Cultivars

This study was carried out to determine the effects of different salt concentrations on germination and seedling growth sweet sorghum [Sorghum bicolor var. saccharatum (L.) Mohlenbr.] cultivars. The research under laboratory conditions cultivars Ulusoy, Sorge, Biomarl?, Erdurmu?, Gül?eker were used as plant material. Five four (NaCl) (0-, 100-, 200-, 300 mM) subjects experiments which set up in randomized plots a factorial design with 4 replications. In study, parameters such percentage (GP), mean time (MGT), index (GI), coefficient uniformity (CUG) speed (GS), root shoot fresh weight, dry length, lateral number length investigated. As result research, it determined that (excluding MGT) decreased concentration increased. decrease characteristics significant at 100 mM dose according average values cultivars, observed more sensitive stress development stage than stage. there differences between genotypes salt-stressed during stages. this sense, Ulusoy Erdurmu? prominent terms tolerance. It is important use tolerant considering genotypic cultivation salt-affected areas.
