Effects of proline application on vegetative growth, chemical characters and photosynthetic pigments of (Coriandrum Sativum)‎ grown under varying salt stresses

Abstract EN

A hydroponic experiment was conducted to assess the role of spraying amino acid proline at concentrations of 0 and 500 mg.l-1 on the alleviation of salt adverse effects that imposed on growth of Coriandrum sativum at levels of 0, 4, and 8 dS.m-1 .

The results showed that spraying proline with (500) mg.l-1 significantly increased plant height, flower number, vegetative fresh weight, root fresh weight, root moister percentage, Chlorophyll b and carotene percentge as compared to untreated plants.

Salinity 8 dS.m-1 decreased the number of leaf and branch/plant, whereas the interactions between salinity NaCl levels and 500 mg.l-1 proline substantially caused significant difference in most of detected vegetative traits.
