Induction and growth curve of calli from leaf and nodal explants of genipap
de Oliveira, Annie Carolina Araújo; Machado, Caroline de Araújo; Resende de Oliveira, Leila Albuquerque; Padilha, Francine FerreiraThe aim of this study was to determine the effect of the auxin 2,4-D (2,4-dichlorophenoxyacetic) in calli formation from leaf and nodal segments of genipap and to characterize its growth curve. Explants obtained from shoots previously established from in vitro seedlings were used for calli induction. The experimental design was completely randomized in a 3x5x2 factorial with three accessions (NB, SA, SAL), five...
Difusão de tecnologia para melhoria da produção de abacaxi em Sergipe
Teixeira, Kelly Cristina dos Santos; Costa, Ana Carolina Salmeiro; Rittes, Jackeline; Vilanova Neta, Jaci Lima; Lédo, Ana da SilvaSão Cristóvão, SE; A cultura do abacaxi em Sergipe apresenta-se, ainda, de forma rudimentar, no que diz respeito às modernas práticas culturais. Há no estado uma priorização de plantio da cultivar Pérola, embora esta seja susceptível à doença causada por um fungo, a fusariose, causando até 50% de perda na produção. Outro fator que causa esta baixa produtividade é o uso de mudas de procedência desconhecido ou se...
Physicochemical characterization of banana fruit by univariate and multivariate...
Lédo, Ana da Silva; Silva, Tatiana Nascimento; Martins, Carlos Roberto; Silva, Ana Veruska Cruz da; Lédo, Carlos Alberto da Silva; Amorim, Edson PeritoBreeding genotypes need to be characterized and evaluated in different soil and climatic conditions. There are few studies on association between characters evaluated and their contribution to banana genetic diversity, being essential to guide genetic breeding programs. This study aimed to evaluate the physicochemical characters of banana genotypes, to estimate associations between characters, to determine the ...
Bromelain enzyme from pineapple: in vitro activity study under different microp...
Vilanova Neta, Jaci Lima; Lédo, Ana da Silva; Lima, Aloisio André Bonfim; Santana, José Carlos Curvelo; Leite, Nadjma Souza; Ruzene, DeniseThe aim of this work was to evaluate the activity of bromelain in pineapple plants (Ananas comosus var. Comosus), Pérola cultivar, produced in vitro in different culture conditions. This enzyme, besides its pharmacological effects, is also employed in food industries, such as breweries and meat processing. In this work, the enzymatic activity was evaluated in the tissues of leaves and stems of plants grown in c...
