Abstract
Floral biology and reproductive mechanisms of Mussambê (Cleome spinosa Jacq) aiming at the plant breeding. Some plants from Cleome genus in Capparaceae family are used as medicinal and ornamental plants. The aim of this work was to study the floral biology and the reproductive mechanisms of C. spinosa to the plant breeding. Anthesis occurred between 17:30 to 18:30. The anthesis process is intimately related to climatic conditions. The main flower visitors were bees (Apis, Bombus), butterfl ies and bats (Glossophaga). Cleome spinosa presents mating system with predominance of outcrossing over the self-crossing, what it can evidences the wide reproductive flexibility of this species and emphasize the genetic variability, which is essential for evolution.Downloads
