To assess the potential of different genotypes of Brazilian oil palm (Elaeis guineensis Jacq.) to somatic embryogenesis and somatic embryo proliferation, mature zygotic embryos of nine commercial genotypes of E. guineensis (BRSC2001, BRSC2328, BRSC2301, BRSC3701, BRSCM1115, BRSC7201, BRSC2528, BRSC2501, and BRSCN1637) were used. Explants were incubated on(More)
Understanding the fate and dynamics of cells during callus formation is essential to understanding totipotency and the somatic embryogenesis (SE) mechanisms. In the present study, the histodifferentiation events involved during the acquisition and development of somatic embryogenesis in oil palm (Elaeis guineensis Jacq.) was investigated. Zygotic embryos(More)
This study aimed to assess changes in peroxidase activity and total protein content of cut flowers of Strelitzia reginae that were treated with the chemical preservatives 8-hydroxyquinoline citrate (8-HQC) or chlorine during cold storage. The bases of the cut flowers were immersed in 1.5 L of tap water with 48 h pulsing treatments (a control with no(More)
BACKGROUND Vascular remodeling, the dynamic dimensional change in face of stress, can assume different directions as well as magnitudes in atherosclerotic disease. Classical measurements rely on reference to segments at a distance, risking inappropriate comparison between dislike vessel portions. OBJECTIVE to explore a new method for quantifying vessel(More)
