| Summary, etc. |
Caesalpinia echinata (brazilwood)is a threatened tree endemic to the Brazilian Atlantic forest with a global importance as it is worldwide used to manufacture the most desirable bows for violins, violas, and cellos. Although there is an international initiative for its conservation, there is a lack of studies on the reproductive biology of the species, as for the genus, a fundamental understanding for the conservation of any species. In this paper, we investigated the phenology, pollination, and breeding system of C. echinata, presenting some conservation guidelines for the species, together with a review of studies on the reproductive biology in Caesalpinia s.l. The genus has a complex taxonomic history with recent attempts to reassign its limits. Pending a final resolution of the placing of some species (including C. echinata)our revision covers the traditional Caesalpinia s.l. and includes annotations indicating to which segregate genus each species is now considered to belong, as well as the appropriate combination where this has already been published. Field work was undertaken from October/2004 to December/2006 at the Tapacurá Ecological Station, northeastern Brazil. Flowering occurred mainly in the dry season and the peak of seed dispersal was at the beginning of the wet season. Anthesis is diurnal, lasting 1 day. The flowers are zygomorphic, yellow, sweet-scented, and the effective pollinators were mainly medium-sized to large bees of the genera Centris and Xylocopa, together with the introduced Apis mellifera. Nectar volume and sugar concentration averaged 2.9±1.0 ?L and 29.5±9.4 per cent, respectively. The ovary has 1-4 ovules (2.35±0.58)and the pollen/ovule ratio was 5631.2; pollen viability was high (95.9±4.8 per cent). Natural fruit set was low (9.2 per cent)with mature fruits averaging 1.7±0.9 seeds. Results of the controlled pollinations and analysis of pollen tube growth revealed C. echinata presents late-acting self-incompatibility. The pollination biology and breeding system of C. echinata are discussed, together with available data on its genetics and physiology, in terms of best conservation practice for this endangered species. Data on the reproductive biology of the genus are scarce, revealing the predominance of bee pollination and SI system, with the occurrence of late-acting self-incompatibility mechanisms in some species. |
