Effect of Salt Stress on Seedling Growth of Sunflower (Helianthus annuus L.)

Chetukuri Anuradha

Abstract :

Sunflower (Helianthus annuus L.) is becoming an increasingly important source of edible vegetable oil throughout the world because of its high polyunsaturated fatty acid content and no cholesterol. The increasing demand for this oil may promote increased hectare of sunflower in the India, where some soils are saline or have the potential to become so. Effects of salt stress on seed germination and seedling growth characteristics were evaluated for twelve Helianthus annuus L. genotypes in Five treatments of salinity including 0.0 (control), 0.0 (Control), 0.4, 0.9, 1.3 and 1.7 dS/m concentration of NaCl in a three replicated randomized completely block design (RCBD). ANOVA revealed highly significant differences for fresh weight and dry weight and leaf area etc., under various salt concentrations. However, the differences among the genotypes for all the parameters studied were highly significant. The findings suggest that, SFL–07 and PKVSH–27 genotypes were found to be tolerate moderate levels of salinity and can be tried for cultivation on marginal salted soils.
