We analyze some convexity properties of the image maps on symplectic cones, similar to the ones obtained by Guillemin-Sternberg and Atiyah for compact symplectic manifolds in the early 80's. We prove the image of the moment map associated to the symplectic action of an n-torus on a symplectic cone is a polytopic convex cone in R n : Then, we generalize(More)
The present study is the first account of in vitro carotenoid pigment induction in Cleome rosea, a Brazilian herbaceous species frequently found near the coast in ecosystems submitted to intense anthropic degradation. Micropropagated plants obtained from in vitro roots were used as source of internodal explants for callus cultures. The callus cultures were(More)
