Transpiration rate, leaf area and dry weights of shoots and roots of three broad bean (Vicia faba L.) lines, 900-3, 67 and 13 were significantly reduced with the increase in salinity. Treatments (seed soaking, or spraying) with vitamins B6 (pyridoxine) or PP (nicotinamide) exhibited variable effects. The rate of transpiration was significantly reduced in treated plants at all salinity levels compared with untreated salinized plants. However, vitamin treatments generally exhibited a significant increase in the leaf area and dry matter yield of salt stressed bean lines, resulting in a complete alleviation of the adverse effect of the high levels of salinity.
