Abstract

Increasing the salt tolerance of SUGARCANE (Saccharum officinarum L.) is an important goal due to the semi-arid climate and SALINITY stress of its cultivation area in our country. An experiment was carried out to determine the effect of sodium chloride on morphological characteristics of eight commercial and promising SUGARCANE cultivars at formative stage using 0, 0.25, 0.5, 0.75 percents NaCl in a HYDROPONICS system. The results showed significant differences among the cultivars for all traits at different salt levels. Increase of SALINITY concentration decreased growth of SUGARCANE cultivars and their traits such as: dry weight, plant height, tiller numbers, leaf area and leaf number per plant. But the trend of reduction was slower for tolerant genotypes. Number of green leaves and number of tiller per plant had the highest percentage of decrease and leaf width and total number of leaves percents had the lowest one. CP65-392 cultivar identified as the most sensitive genotype at this growth stage because of its death at all salt levels. NCO-310 as a cultivar with high yield potential at non stress and low stress conditions had the highest growth rate at zero and 0.25% NaCl salt levels. At medium and high salt levels CP72-2086 and CP82-1592 genotypes had the highest growth rate and dry weight, respectively. Although these two cultivars had lower yield than NCO-310 at nonstress conditions, they had more salt tolerance potential. Therefore, these two cultivars seem to be beneficial in SUGARCANE breeding program due to their higher production under SALINITY stress condition. Assessment of sodium and potassium concentrations revealed that NCO-310 and CP82-1592 ranked as the most tolerant genotypes, having the highest potassium to sodium ratio, respectively.
