Action of nitric oxide on the physiological potential and biochemical mechanisms of pea seeds

Abstract: Nitric oxide (NO) can act in biochemical pathways of the germination process; however, there is little information about how it acts on performance pea seeds. The aim this study was to evaluate physiological and effects NO seed vigor. Pea seeds cv. Itapuã 600 obtained from three lots with different levels quality were sown a substrate moistened water (control) or sodium nitroprusside (SNP) solution, donor (50 μM), assess germination, vigor, activity antioxidant enzymes, reactive oxygen species, lipid peroxidation, amylase activity. application does not alter but increases It more effective lower potential. In addition, leads reduction oxidative stress, favors translocation reserves embryo, has potential for use treatment increase
