Seed germination and seedling growth of bean (Phaseolus vulgaris) as influenced by magnetized saline water

Abstract

Magnetized water is considered eco-friendly physical presowing seed germination.The aim of this study was to evaluate the effects of magnetized watertreatments on bean (Phaseolus vulgaris) germination under saline conditions (0, 25, 50, 75, 100 and 120 mM NaCl). This experiment was performed as factorial in a complete randomized design (CRD) with three replications. The results revealed that the roots and shoots length, fresh and dry weight of shoots and roots and roots to shoots ratio, chlorophyll content index, water uptake, tissue water contentwere significantly affected by magnetized water.Irrigation with magnetized water significantly increased the physiologic factors such as germination percentage and index, vigor index and salt tolerance index, compared to untreated control seeds.Mean germination time and parameters T₁, T₁₀, T₂₅, T₅₀and T₉₀ (required time for germination of one to 90 percent of seeds) were reduced significantly in all magnetized water treated plants in comparison to control.The results also demonstrated that magnetized water was conducive to promote the growth of bean seedlings under saline conditions.
