Sementes e plántulas de andiroba (Carapa guianensis Aubl. e Carapa procera D.C.): aspectos botánicos, ecológicos e tecnológicos
In the Amazon Basin occur both species of the genus Carapa (Meliaceae). Roba-mahogany is weel known for the quality of its timber and the oil extracted from its seeds. The provision of basic information on seed and seedlings to subsidize scientific studies and the propagation and management of these species was the objective of this study. Bio-morphology of the fruits, seeds and seedlings, and a comparative botanical description, allow the distinction of both species. The natural distribution, abundance and phenology are presented,as well as factors which may influence the natural regeneration, as the high seed predation and the infestation by Hypsipyla grandella. Roba-mahogany trees have large seeds (with and average weight of 25g - C. guianensis and 16g - C. procera) with a regular fructification. However, there are difficulties in seedling production due to desiccation and chilling sensitivity of the seeds. The thickness of the seed coat may cause dormancy of C. guianensis which may delay the germination until six months. Seeds of C. procera, which normally have a thinner seed coat need in average only one month to germinate. Nursery practices and planting, as well as the use of these species are commented.
