This study was conducted to determine the effects of seed soaking in salicylic acid (10 -2 mol/L, 10 -4 mol/L, 10 -6 mol/L and control) on the growth and some physiological characters in wheat (Triticum aestivum L.) under salinity (8 ds m -1 ) and non salinity conditions. NaCl reduced the emergence percentage, the growth parameters (shoot and root dry weight), K + /Na + ratio, osmotic potential and photosynthetic pigments (Chl a, b and carotenoids) contents in wheat seedlings. The emergence percentage was not changed, in contrast, shoot and root dry weight of seedlings, K + /Na + ratio, photosynthetic pigments (Chl a, b and carotenoids) contents and osmotic potential were increased by salicylic acid treatments under non salinity condition. Seed soaking in SA increased the emergence percentage, osmotic potential, shoot and root dry weight, K + /Na + ratio, photosynthetic pigments (Chl a, b and carotenoids) contents in the salinity stressed wheat seedlings. These results were indicated that SA has positive effects on plant growth in salinity and non salinity conditions. But the effects of SA was higher on emergenge percentage, K + /Na + ratio and osmotic potantial in salinity condition compared to non salinity condition was obtained in this study.

yetiştirme sezonunda tek lokasyonda yürütülmüştür. Şansa bağlı tam bloklar deneme desenine göre dört tekerrürlü olarak yürütülen bu araştırmada, on üç arpa (Tokak 157/37, Aydanhanım, . It was concluded that cv Tarm-92, cv Orza-96, cv Tokak 157/37 and cv Bülbül-89 had higher yield than other cultivars in Van regional conditions.

Öz: Bu araştırma, farklı salisilik asit dozları (0 mg da ) and treatments (pre-soaked seed and foliar application) on wheat local Tir variety (Triticum aestivum L. ssp vulgare Vill. v. Leucospermum Körn) and lentil (Lens culinaris medic. cv Kayı-91) crops under dryland condition of Van in 2004-05 winter growing season. As results of this study, plant height was affected but, spike number per m 2 , spike length, grain number per spike, grain weight per spike, thousand grain weights and grain yield was unaffected by salicylic acid treatments in wheat. But salicylic acid doses effected all yield components and grain yield except spike number per m 2 and thousand grain weights. The highest grain yield was obtained from 12.810 g da -1 salicylic acid application with 276.58 kg da -1 and grain yield were increased 24.8 % compared to control doses in wheat. In lentil, salicylic acid doses and treatment didn't affected number of plant per m 2 , plant height and thousand grain weights. The increasing of salicylic acid doses increased number of branches per plant, number of seeds per plant, seed weight per plant and seed yield in lentil. Moreover, different salicylic acid treatments affected branches per plant and number of seed per plant. The highest seed yield was obtained from 12.810 g da -1 salicylic acid doses application with 141.60 kg da -1 and seed yield were increased 35 % compared to control doses in lentil.
