دراسة مقارنة عن فسلجة التحمل الملحي لنباتي الفاصولياء (phaseolus vulgaris L.)‎ و اللوبياء (vigna sinensis L.)‎

Abstract EN

A comparative physiological study of the salt tolerance of two plant species kidney bean (Phaseolus vulgaris L.) and cow pea ( Vigna sinensis L.

) have been carried out .

The study included the effect of NaCl at concentrations ( 0 , 50 , 100 , 150 and 200 ) m Mol / L on the concentrations of proteins , proline and carbohydrates , as well as of plant pigments ( chlorophyll and carotenoids ) in the shoot system . The results of the study were revealed that , an increase of salinity caused increase in proteins , proline and carbohydrates , and a decrease on the concentrations of plant pigments ( chlorophyll A and B ) , total chlorophyll and carotenoids in the shoot system of the two plant species at all concentrations , and a clear significance differences were noticed .
