In vitro establishment and early development of barueiro (Dipteryx alata Vogel)

Abstract: The barueiro (Dipteryx alata Vog.) is a native fruit species of the Cerrado ecoregion that has multiple uses. It is a wild species, and its cultivation is difficult. Furthermore, it is threatened with extinction. Plant tissue culture is a major tool for the conservation of germplasm, as well as a means of propagating highquality seedlings on a large scale. However, this technique has not been used with barueiro, although it might provide valuable contributions to the process of barueiro domestication. The most… Show more

“…Additionally, the status of the seed coat did not interfere in germination for the species under study. Silva et al (2016) evaluated the in vitro germination of Dipteryx alata and found a germination rate of up to 88.88% when submitted to NaClO in MS medium supplemented with 0.3 % activated carbon (p/v), similarly to the present study. In where: *Means followed by different letters differ significantly according to Tukey's test (α=0.05); NaClO = sodium hypochlorite.…”

“…controlado dos recursos naturais pode viabilizar a manutenção dessa prática tradicional, além de permitir a conservação e o estudo do patrimônio genético(VIEIRA NETO et al, 2009). Empresa Pernambucana de Pesquisa Agropecuária -IPA mantém na Estação Experimental de Porto de Galinhas uma reserva de aproximadamente 1,3 hectares(SILVA JÚNIOR et al, 1999).Existem outras coleções de mangabeiras na Embrapa Cerrados (Planaltina-DF), naEmbrapa Amapá (Macapá-AP) e na Embrapa Meio-Norte (Teresina-PI) e outras em universidades e organizações estaduais de pesquisa agropecuária (COELHO, 2016b). Na Universidade Federal de Alagoas, as mangabeiras são conservadas ex situ(ESPÍNDOLA et al., 1992), assim como nos bancos de germoplasma da Empresa Estadual de Pesquisa Agropecuária da Paraíba -Emepa-PB (BARREIRO NETO, 2003) e da Escola de Agronomia da Universidade Federal de Goiás (VIEIRA, 2014).Apesar de haver coleções de mangabeira conservadas em campo, a vulnerabilidade dos acessos nesse tipo de coleção é grande, pois as plantas ficam expostas ao ataque de pragas e patógenos, a intempéries climáticas ou ao vandalismo, podendo ser perdidas também por causa de falhas de identificação ou erros humanos (WITHERS; WILLIAMS, 1998).…”
