Resumo: Seeds of several tree species from Brazilian wet forest are in dangerous situation and show recalcitrant characteristics. Therefore, it is not possible to store them by traditional methods adopted with orthodox seeds and it limits their genetic resources ex-situ conservation in seed banks. This situation encourages researches to find news technologies in order to store these species in genebanks. Therein, flash-drying method for embryos desiccation shows to be a promising technique in order to resolve seed conservation of Brazilian endogenous tree species in genebanks. This paper has an objective of to become known the flash-drying technique and to be accessible to seed  physiologists

This paper has an objective of to become known the flash-drying technique and to be accessible to seed  physiologistsSementes de diversas espécies arbóreas das florestas úmidas brasileiras, grande parte delas ameaçadas de extinção, apresentam características recalcitrantes, significando que não toleram desidratação, não sendo possível o seu armazenamento pelos métodos tradicionais realizados com sementes ortodoxas. Dessa forma, o comportamento "recalcitrante" das sementes limita a conservação ex-situ dos recursos genéticos, especialmente dessas espécies florestais em bancos de sementes. Esse fato estimula pesquisadores a buscarem novas tecnologias visando a conservação genética dessas espécies. Nesse sentido, a técnica denominada "flashdrying" ou desidratação ultra-rápida de embriões mostra-se promissora para resolver ou amenizar o problema de conservação de espécies brasileiras com sementes recalcitrantes. Este trabalho tem como objetivo reunir informações e divulgar a técnica de desidratação ultra-rápida ou "flash-drying", tornando-a amplamente acessível aos profissionais da área.Embrapa Florestas2010-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/136Pesquisa Florestal Brasileira; n. 54 (2007): jan./jun.
