Germination and regeneration of Eugenia involucrata (Myrtaceae) seeds correlated with reactive oxygen species

Abstract: Seeds of the genus Eugenia L. (Myrtaceae) have interesting propagation strategies, and reactive oxygen species (ROS) seem to be related their germination seedling production. In this study, effects ROS on E. involucrata seeds were analyzed indirectly, with application N-acetyl-L-cysteine (NAC), an antioxidant. The results demonstrated that incubation in NAC suppressed and/or delayed seeds, as well regeneration roots aerial parts. higher concentration NAC, greater seed regeneration.
