Abstract :Phenylalanine ammonia lyase response to zinc and lead toxicity of two different wheat genotypes insert ignore into journalissuearticles values(Triticum aestivum L. cv. Kıraç66 and Triticum durum Desf. cv. Kızıltan-91); were investigated in this study. The seedlings which were cultivated for 6 weeks in greenhouse conditions were harvested from the surface of soil. At the end of 6th weeks, seedlings were transferred to jars which filled full Hoagland nutrient solution. The zinc and lead stress treatments were carried out with addition of 0 insert ignore into journalissuearticles values(control);, 100 mg/L, 200 mg/L, 300 mg/L zinc and lead in nutrient solution. It was determined that phenylalanine ammonia lyase activity increased in seedlings under zinc and lead stress. The highest phenylalanine ammonia lyase activity was determined in treatment 200 mg/L Pbon fourth day in cv. ‘Kızıltan-91’genotype. These data show that phenylalanine ammonia lyase activity appear to protect wheat seedlings against stressrelated damage
