Studying Effect of Salinity Stress on Germination, Proline and Carbohydrate Content in Thyme (Thymus vulgaris L.) Seedlings

Thyme is a important medicinal plant that effective by different environmental stresses. In this studying, physiological effects of salinity stress in four levels of sodium chloride (NaCl) included blank (distilled water), 50, 100 and 150 m/mol on germination percent, proline and carbohydrate concentration in Thyme seedlings was studied. In relation with germination percent was observed that increasing of salt level was reduced which in statistical level of 0/01 showed meaningful difference. Also results expressed increasing of leaf proline and carbohydrate content that was synchronized with increase of sodium chloride that this increasing in statistical level of 0/01 was meaningful. This results show that salinity stress effects on Thyme growth that plant for defend increase proline and carbohydrate concentration in tissues.
