**5.4 Sorghum (***Sorghum bicolor* **L.)**

Sorghum which is mostly grown in Australia in the world, is a monocotyl C4 plant that belongs to the *Poaceae* family. Even though sorghum has a high tolerance against salt concentrations, salt stress has a big role in plant growth deceleration [42]. In soils with high salinity, ion toxicity and toxicity-induced mineral deficiency are observed [43]. Tolerable salt concentration for grain sorghum is 6.8 dS/m−1 and when salinity reaches 7 dS/m−1 25% decrease is observed in yield and when salinity reaches 10 dS/m−1 a 50% decrease is observed [44]. Under salinity, while germination rate decreases, germination time increases [45]. Plant stem yield and soluble carbohydrate decrease with increasing salinity [46].
