Dormancy breaking and biochemical processes associated with germination of Erythrina falcata Benth. seeds

Background: The aim of this research was to investigate the efficiency methods overcome primary dormancy and biochemical processes associated with germination Erythrina falcata Benth seeds. Seeds were submitted overcoming treatments water uptake pattern analysed. We then evaluated activity antioxidant enzymes SOD, CAT, APX, quantified lipid peroxidation levels, hydrogen peroxide content total protein content. experiments performed in a completely randomized design statistical analysis used Scott-Knott test at 5% probability. Results: Mechanical scarification sandpaper leads approximately 94% E. falcata, while control non-scarified seeds show only 37% germination. Treatments hot led high mortality Rapid absorption observed first 18 hours imbition when scarified sandpaper, radicle emergence after 36 hours. During imbibition there an increase enzyme decrease H2O2 production, suggesting efficient mechanism for regulating damage. A during Conclusions: is method breaking reduction production peroxidation, enzymes. decreased along time.
