Abstract :The effect of varying boron insert ignore into journalissuearticles values(B); concentrations on seed germination of the most commonly cultivated bread insert ignore into journalissuearticles values(Triticum aesti-vum L.); and durum insert ignore into journalissuearticles values(Triticum durum Desf.); wheat cultivars insert ignore into journalissuearticles values(Bezostoja-1, Gerek-79, Gün-91 and Kızıltan-91, Kunduru-1149, Selçuklu-97, respectively); in Central Anatolia were investigated by in vitro and pot experiments. In vitro experiments were carried out in 200 ml jars containing 50 ml MS with 0.7 % agar, 3 % sucrose and different con-centrations of B insert ignore into journalissuearticles values(0, 1.08, 3.24, 9.72, 29.16 ppm);; pot experiments were also done in 0, 1.08, 3.24, 9.72, 29.16 ppm B added pots. The experiments were set up according to completely randomized design with 3 replications. Although B concentrations had no significant effect on seed germination in all cultivars, cultivar and cultivar x B interac-tions were significant. It is suggested that in vitro studies can be an alternative approach to pot and field studies in determining the responses of plants to microelements. However, if determination of B level inhibiting seed germination is the primary re-search target B levels higher than 29.16 ppm B should be considered as the minimum threshold to set up the experiments becasue B levels at or lower than this threshold did not seem to effect germination rates in the cultivars studied.
