Germination and initial growth of common bean plants under water deficit as affected by seed treatment with S-nitrosoglutathione and calcium chloride

New practices to improve the germination and the initial establishment of seedlings are needed to improve crop development in rainfed areas, where drought events may happen just after sowing. Here, we tested the hypothesis that pre-treatment of common bean seeds with S-nitrosoglutathione (GSNO)—a nitric oxide donor (NO)—or calcium (Ca2+) improves the germination and initial seedling growth under water deficit and both, together, will act...
