Abstract
Experiments were conducted with Demre long pepper cultivar in a climate chamber with controlled climate parameters and in a hydroponic system with Hoagland nutrient solution. Three-week old seedlings were subjected to 100 mM NaCl treatments and samples were taken on 10th day of the treatments for physiological and biochemical analyses. With the idea that gibberellic acid reduces negative impacts of salt on plants and regulates ion uptake, thus provide an ion balance, plants were also subjected to Gibberellic acid (GA3) treatments at different doses (5ppm, 7.5ppm and 10ppm). Then, leaf samples were taken again on 10th day of treatments and Na, K, Ca and Cl analyses were performed on samples. Present findings revealed that GA3 treatments together with NaCl treatments recessed plant growth and development, but provided significant contributions in regulation of ion uptakes and providing an ion balance. The best GA3 doses for plant growth and ion balance were identified as 7.5 and 10 ppm.
