Abstract :The aim was to evaluate the salicylic acid effects on the germination and growth of maize cultivars exposed to salinity stress levels. The investigation was set according to the factorial experimental design in completely random blocks with four replications. The maize (Zea mays L.) cultivars (Side, Pehlivan and Burak) was chosen as plant material. NaCl compound was used for solutions prepared at concentrations of 0-75-150 mM and and salicylic acid in doses of 0-0.1-0.2 mM. The growth parameters in Side cultivar was naturally higher than the other cultivars. The minimum means prominently were indicated in Pehlivan cultivar. As anticipated, the maximum means were realised in control, as the minors were reported in 150 mM NaCl application. Due to the unfavorable influence of salinity, only the germination time gave the highest average at 150 mM. The most affected feature was determined root length, 150 mM NaCl was three times lower than control. The fact that the best germination time was obtained at 0.2 mM SA, as the worst was recorded at 0.1 mM SA, that explained the complex effect of SA. Germination index impressed substantially and regularly with enhancing SA applications. Augmenting SA dose caused a well elongation in shoot length, moreover by contrast lead to shortening in root length, but these were not numerically markedly different. Albeit, the root length of the control application was well, the best value in fresh weight was recorded at 0.2 mM SA. In this experiment, realised that salicylic acid applications diminished and ameliorate this effect under salinity stress conditions that maize seeds may encounter during the germination period.
