Priming Urochloa ruziziensis (R.Germ. & Evrard) seeds with signalling molecules improves germination

Abstract: As forage production increase, high-quality seeds demand follows. Priming have been reported as a technique for improve seed quality and stress tolerance. The aim of this study was to evaluate the priming agents effect on Urochloa ruziziensis germination seedling establishment under water deficit salt stress. A completely randomized experiment assessing six three conditions were established. We evaluated: content; percentage speed index; viability remaining from test; length; antioxidant enzymatic activity; malondialdehyde quantity. Seeds primed showed better physiological performance than dry seeds. There significant increase in roots shoots length. Sodium Nitroprusside shows potential use U.
