Abstract

Calcium ion has important effects on physiological processes of plants and improves the morphological and biochemical parameters of the plant which is under SALT STRESS. SALT STRESS because of ION TOXICITY and interference with nutrients, affects parameters such as seed GERMINATION, root and shoot dry weight, quantity of proteins, proline accumulation, lipids peroxidation and others. Plants are able to use calcium ion to improve their efficiency under SALT STRESS. How much they can use calcium to compensate losses during stress depends on their efficiency. In this experiment, we used Descurainia sophia L. plant which is a highly sensitive plant to SALT STRESS. Plants which were grown in vermiculite in control room (temperature 23°c, humidity 44%, light 8.23 Klx) were treated with salts (0,25,50,75 and 100Mm NaCl) either with or without 5 and 10mM calcium. After 8 weeks under such treatments, all parameters were measured and analysed with SPSS Version 9.0. Results showed that the optimal concentration of calcium for maximum resistance depends on plant species and salt treatments that used. For most parameters, 10mM Ca2+ concentratin was toxic and 5mM concentration of this ion improved parameters in SALT STRESS condition. SALT STRESS because of osmotic effects and Na+ toxicity, decreases plant growth and change plant parameters quantities. The threshold of this plant to salinity, is 50Mm NaCl. SALT STRESS beyond this threshold, significantly improved which plants were treated first with Ca2+.Our conclusion is using the plants with high CAER, can decrease economical expenses of plants in response to SALT STRESS and improve growth efficiency.
