Sealing and explant types on the mangaba micropropagation

Abstract: In micropropagation, especially for mangaba tree botanical variety of Northeastern Brazil, limiting aspects such as ethylene accumulation in the cultivation flask and loss of vigor in subcultures have been observed. This study was aimed at assessing the technical and scientific knowledge of the in vitro propagation of botanical mangaba tree variety and at improving the micropropagation protocol, establishing the in vitro cultivation time, the best type of flask sealing and explant at different micropropagation… Show more

“…growth of shoots was observed in the basal and intermediate segments, independent of BAP concentration in the media. Thus, the lowest multiplication rate observed on apical explants of canjerana, might have occurred probably due to the adventitious shoots regenerated from the apical portion, which presented less vigor and therefore is being more sensitive to ethylene accumulation (Sá et al, 2012). Similar results were reported by Anis and Faisal (2005), who observed a higher rate multiplication in nodal segments of Psoralea corylifolia.…”

“…Dos 13 estudos agrupados na área reprodução vegetal, 12 se referem especificamente à reprodução in vitro da mangabeira, tanto de maneira sexuada, isto é, por meio de sementes (Pereira-Netto 1996;Machado et al 2004;Lédo et al 2007;Reis 2011;Cabral et al 2013), quanto assexuada, por meio de segmentos nodais Lédo et al 2011;Jesus Sá et al 2012), segmentos caulinares (Soares et al 2007), microestacas (Jesus Sá et al 2011) e calos (Fráguas et al 2009). Todos os autores justificam seus estudos no fato de a mangabeira obter baixas taxas de germinação em viveiros, o que interfere no aproveitamento da espécie em larga escala, quer para usos econômicos ou para conservação florestal.…”

“…O período de cultivo in vitro está relacionado ao comportamento e desenvolvimento da espécie nas determinadas condições do ensaio. Algumas espécies podem permanecer meses em um mesmo meio nutritivo sem a adição de fitorreguladores, ao passo que outras conseguem sobreviver apenas algumas semanas (Sá et al, 2012;Xavier et al, 2013).…”
