Abstract

A greenhouse experiment involving four levels of boron (B) (0, 5, 10, and 20 mg kg-1) and three levels of zinc (Zn) (0, 10, and 20 mg kg-1) was conducted on tomato (Lycopersicon esculentum Mill., cv. 'Lale'). Boron toxicity symptoms occurred at 10 to 20 mg kg-1 B levels. These symptoms were partially alleviated in plants grown with applied Zn. Fresh and dry plant weightS were strongly depressed by applied B. However, Zn treatments redUced the inhibitory effect of B on growth. Increased levels of B increased the concentrations of B in plant tissues to a greater extent in the absence of applied Zn. Both Zn and B treatments increased Zn concentration of the plants.
