Influence of boron and calcium on the tolerance to salinity of nitrogen-fixing pea plants

摘要: The effects of different levels B (from 9.3 to 93 μM B) and Ca 0.68 5.44 mM Ca) on plant development, nitrogen fixation, mineral composition pea (Pisum sativum L. cv. Argona) grown in symbiosis with Rhizobium leguminosarum bv. viciae 3841 under salt stress, were analysed. addition extra the nutrient solution prevented reduction caused by 75 NaCl growth inhibition nodulation fixation. number nodules recovered increase concentration at any level, but only developed high concentrations could fix nitrogen. Addition during restored nodule organogenesis structure, which was absolutely damaged salt. tolerance symbiotic plants mediated can be co-related recovery contents some nutrients. Salinity produced a decrease both shoots nodulated roots, being increased supplement elements solution. also reduced content other nutrients important for development particularly as K Fe. A balanced nutrition (55.8 B, 2.72 able counter-act deficiency these salt-stressed plants, leading huge salinity plants. necessity nutritional studies successfully cultivate legumes saline soils is discussed proposed.
