Abstract

As for of the importance and extension, water and soil SALINITY besides the remarkable increase of these kinds of farms and the increasing need of the country for fodder crops, an experiment was conducted to assess the tolerance to the SALINITY of sorghum cultivars. Five fodder sorghum cultivars as their tolerance to SALINITY in germination and seedling growth periods were evaluated, In a CRD base factorial with three replicates, with solutions in five different SALINITY levels as 0, 75, 150, 225 and 300 Mmol NaCl were carried out in laboratory, pot and hydroponic system. Germination test was done on ISTA rules and on the 3rd, 7th, and 10th days sampling was made on a number of germinated seeds, radical, plumule and plantlet length and plantlet dry weight. Increasing SALINITY levels decreased radical, plumule and plantlet length and plantlet dry weight, germination percentage, germination rate coefficient and increased germination spread time and R/S ratio in all cultivars. KFS2 with higher germination percentage, plantlet dry matter, plantlet length, and germination rate was the most tolerant and KFS1 was the most sensitive cultivar to SALINITY among cultivars. In greenhouse as hydroponic experiment, leaf area, plant height, shoot, root, stem, leaf dry matter and leaf and tiller number were measured. SALINITY decreased all measured attributes but increased root/shoot ratio. Based on these experimental results KFS3 with higher leaf area and weight, stem and shoot weight was the most tolerant and Jumbo was the most sensitive one among cultivars to SALINITY.
