Title Growth and Mineral Distribution of Sesuvium portulacastrum L a Salt Marsh Halophyte, Under Sodium Chloride Stress
Source Communications in Soil Science and Plant Analysis
Abstract Response of Sesuvium portulacastrum L., to the elogenous addition of sodium chloride (NaCl), applied at different concentrations ranging from 100 to 900 mM was evaluated. Leaf area, shoot and root weight of the treated plants were increased significantly. Total nitrogen (N) content of leaves, stem and root was significantly increased up to 600 mM NaCl, and thereafter declined moderately. Accumulation of potassium (K), and calcium (Ca) were exponentially increased with NaCl treatment as also observed in the case of N. Sodium content of shoot and roots of S. portulacastrum increased significantly with increasing NaCl concentrations. Certain essential elements like copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) were also accumulated in all plant parts significantly, up to 600 mM. However, due to high salinization, growth and development of plants inhibited markedly. Furthermore, elemental concentration decreased beyond 600 mM level of NaCl. Due to aging and senescence, marked changes in leaf area, shoot, root volume and mineral content were observed between sampling time.
