Effect of seaweed extract of Sargassum vulgare on germination behavior of two bean cultivars (Phaseolus vulgaris L) under salt stress

Abstract

Salt stress is a major adverse factor that can lower seed germination and seedlings growth, leading to reduced plant growth and ultimately lower crop productivity in arid and semi arid regions of the world. Bean (Phaseolus vulgaris L.) is an important crop occupying a large area in both Morocco and Tunisia, where salt stress is the most limiting factor. In the present investigation, an attempt has been made to study the effect of seaweed liquid extract (SWE) from Sargassum vulgare at different concentrations on seed germination and seedling growth of two bean cultivars (Phaseolus vulgaris L) under salt stress.
