MOHAMED KAMEL Biología salinity sea water irrigation Vicia faba Osmoregulation The familiar solutes, Na+, K+, Ca2+, Mg2+, Cl-, PO43-, SO42-, soluble carbohydrates, amino acids and soluble proteins, which play a role in osmotic adjustment were estimated to investigate the role of potassium nitrate and ammonium sulphate as osmoregulators and their effects on the solutes composition. Vicia faba L. was cultivated and irrigated with 5, 10, 15 and 20 % (v:v) sea water. The plants were divided to three groups. The first was irrigated with sea water only. The second was treated with 5 mM KNO3 while the third was treated with 5mM (NH4)2 SO4. The plants were left to grow until flowering stage. The results indicated that the non- treated group increased the soluble carbohydrates in the roots to avoid the influx of sodium. The treatment with KNO3 decreased the sodicity (SAR) while (NH4)2 SO4 treatment decreased the SK:Na value in the shoots at higher salinity. The availability of nitrogen as nitrate or ammonium ions enhances the accumulation of soluble carbohydrates in shoots. The plants of all groups were depended on Ca2+, as compatible solute more than Na+, and K+. 2012 artículo científico 0120-548X https://www.redalyc.org/articulo.oa?id=319028028006 en http://www.redalyc.org/revista.oa?id=3190 Acta Biológica Colombiana application/pdf Universidad Nacional de Colombia Acta Biológica Colombiana (Colombia) Num.2 Vol.17 |
