Abstract

This study was carried out to evaluate the changes in some important cell parameters under water limitation in sorghum genotypes. A factorial experiment was conducted based on completely randomized design in greenhouse, in University of Mohaghegh Ardabili in 2014. Treatments included WATER STRESS at levels of 85, 65, 45 and 25 percent field capacity and three genotypes of forage sorghum (KFS2, KFS6 and KFS17). The results showed that WATER STRESS reduced the OSMOTIC POTENTIAL, relative water content, cell membrane stability redecase by one percent, also the amount of potassium, calcium, phosphorus, while increased sodium content and finaly decreased BIOMASS. Interaction between stress and genotype was significant only on PROLINE, soluble sugars, cell membrane stability, relative water content and BIOMASS. KFS2 genotype had the highest amounts of PROLINE, soluble sugars and NUTRIENTS, as well as the highest OSMOTIC POTENTIAL, relative water content, cell membrane stability and BIOMASS in most severe stress levels (25 percent of field capacity). PROLINE and calcium amount had the highest contribution in prediction of OSMOTIC POTENTIAL and membrane stability. These factors also play an important role in BIOMASS production. In general, we can say the genotypes use different mechanisms to deal with stress, however, the genotypes which use faster and less expensive methods have greater tolerance to stress and will produce a higher yield.
