A comparative study of the biochemical compounds found in three species of Vigna (Vigna angularis L., Vigna mungo L. and Vigna radiata L.) under salt stress conditions

Saline soils are an unfavourable environment for the growth of most legumes. The aim of this work is to compare the biochemical behaviour of three species of bean (Vigna radiata L., Vigna mungo L., and Vigna angularis L.) under salt stress conditions. In order to assess this behaviour, we analysed polyphenols and flavonoids in the roots and leaves. The results reveal variability in the accumulation of polyphenols and flavonoids, depending on the organ of the plant, the species, and the intensity of the saline treatment.
