Seasonal Physiological Response of Salicornia Europaea L

Mohamed Mohamed Abd El-Maboud

Terminal shoots of a succulent true halophyte Salicornia europaea was collected from two sites along the Damietta- Port Said coastal road, Egypt during winter and summer, 2019 to determine osmotic potential (op), water content, ash content, Na, K, Ca, Mg, Cl, proline and soluble sugars. Also, associated soil was taken from rhizosphere area to investigate soil physical and chemical characters. Water content, op, Ca, Mg and soluble sugars were reduced in summer, while Na, K, Cl and proline were increased in summer season. All determined parameters were higher in S. Europaea growing at site 2 than those growing at site 1 except in water content did not change significantly. A strong negative correlation was detected between EC of soil and both water content and Mg content in shoot of S. Europaea. In contrast, strong positive correlations were detected between Na and EC, soil moisture, Cl and ash content. Moreover, strong positive correlations were detected among Ca & op, Mg & water content, proline & K, soluble sugars with soil moisture and Ca. Due to high accumulation of ash content, S. Europaea can be invested in saline soil reclamation.
