Vitamins are the functional components of various enzyme-regulated biochemical reactions occurring to create energy. Vitamin contents of plants are known to show altered metabolism under the influence of salinity. Not much of work has been done on the influence of salinity on the vitamin content in higher plants. Present study was carried out to study the influence of NaCl salinity on vitamin content in the leaves of Spinacia oleracea. Spinacia oleracea plants were grown in earthen pots and were subjected to different concentrations of saline water (NaCl) treatment. Control plants were irrigated with tap water. Treatments started after the seedling emergence and continued till the plants were 45 day old. Mature leaves of these plants were harvested and used for studies. Thiamine and riboflavin content were found to increase with increase in NaCl concentration, however, β-carotene was found to decrease with increasing level of NaCl in the growth medium.

Key words:   ascorbic acid, β-carotene, riboflavin, salinity, thiamine, vitamins
