Özet

A greenhouse experiment was conducted with three doses of boron (0, 1, and 10mg B kg(-1) in the form of boric acid (H3BO3). Durum wheat (Triticum durum L. cv: Cakmak-79) and bread wheat (Triticum aestivum L. cv: Gerek-79) cultivars were used as plant material. B toxicity symptoms strongly appeared in durum wheat compared to bread wheat. Applications of B at 1.0mg B kg(-1) stimulated and increased the dry weights of both the cultivars, while high level B application (i.e., 10mg B kg(-1)) depressed and decreased the dry weights significantly. B concentration and uptake in the leaf tip were increased with an increase in B application, whereas calcium (Ca) concentration and uptake were decreased in both the cultivars. It was observed that a substantial amount of B was accumulated in the plant cell wall. As similar to leaf tips, B concentrations in the cell wall also increased with B application, whereas Ca concentration was decreased.
