Abstract | ||||
A pot experiment was conducted to investigate the effect of soaking grains of wheat plants with ascorbic acid in alleviation of the adverse effect of salt stress on wheat growth in parallel with addition of compost rates under three levels of different soil salinity (6, 9 and 12 dS m-1), the grains of wheat divided into two portions, each partition soaked in one only from aqueous solutions, distilled water or 100 mg L-1 of ascorbic acid (AsA). Compost manure was mixed with soil at rates of 0, 100 and 200 g pot-1.The results showed a significantly increase in germination percentage up to 46% with used aqueous ascorbic acid solution compared with distilled water. Furthermore, the results proved that AsA partially counteracted the harmful effect of salinity. Our results indicated that all parameters studied of wheat growth i.e., plant height, number of tillers, number of spikes pot-1 and spike length and yield components i.e., wheat thousand grain weight (g), grain yields (g pot-1) and straw yields (g pot-1) as well as dry weight were improved significantly with used aqueous ascorbic acid solution (AsA) as a cultural practice for grains soaking before sowing, this improving gradually reduction with increasing soil salinity but by little degree compared with distilled water. This result evident that ascorbic acid plays a role in the regulation of a number of metabolic processes which were counteracts the harmful effect of salinity, this roll is more effecting with increasing level of organic mater in soil. | ||||
