Abstract

Some of the plants from Ocimum genus in Lamiaceae family are source of essential oils used in pharmacy, perfume and cosmetics industry. The knowledge of mate systems is extremely important because it allows to define selection strategies based on intra and interpopulation crossbreeding. The aim of this work was to study floral biology and reproductive mechanisms of alfavacão aiming at genetic improvement. The floral activity included three floral stages: first, pre-anthesis, when the pollination happened; second, anthesis, when the asynchronous opening of stamens happened; and third, pos-anthesis, when there was the fecundation of the ova. The anthesis process is intimately related to climatic conditions. The accesses of O. officinalis from Banco de Germoplasma de Plantas Medicinais da UESB (Medicinal Plants Germplasm Bank from UESB), in spite of reproducing, predominantly, by self crossing, may present outcrossing reproduction. This makes evident the wide reproductive versatility of this species, accentuating the genetic variability, which is essential for evolution
