Abstract

The interactive effect of salinity and some vitamins; thiamine, nicotinic acid and pyridoxine on growth and some metabolic changes of wheat (Triticum aestivum L.) were studied. Salinity induced a considerable reduction in growth, pigment contents, carbohydrates and proteins in wheat plants. However, proline contents of the main plant organs were increased progressively with the increase of salinity level. When these salt stressed plants were sprayed with thiamine, nicotinic acid or pyridoxine the growth, pigments and accumulation of carbohydrates and proteins were considerably increased. However, proline contents were decreased as compared with the corresponding treatments with NaCl. These results may lead to the conclusion that, each of the three vitamins used can alleviate the adverse effects of salt stress.
