Embriogênese somática em cana-de-açúcar e aspectos morfoanatômicos
Melo, Emanuelle FerreiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; This study was carried out to evaluate the effects of the different explants types and growth regulators at different phases of the somatic embryogenesis in sugarcane, RB867515 cv., as well as to anatomically characterize the phases of this process in this cultivar. In addition, the in vitro regeneration was evaluated via somatic embryogenesis in cult...
Multiplicação de abacaxizeiros ornamentais em diferentes concentrações de bap e...
Alves, Kamila Antunes; Londe, Luciana Nogueira; Melo, Emanuelle Ferreira; Rodrigues, Gabriel BelfortO mercado mundial de flores tem apresentando grande destaque econômico nos últimos anos. Apesar do estabelecimento das técnicas de micropropagação, melhorias no protocolo ainda são necessárias. Neste sentido, objetivou-se com o presente trabalho avaliar a multiplicação in vitro das espécies de abacaxi ornamental Ananas comosus var. bracteatus e A. comosus var. erectifolius em diferentes períodos de avaliação e ...
Modifications in the metabolism of carbohydrates in (Coffea arabica L. cv. SIRI...
Fernandes, Christiane Noronha; Melo, Emanuelle Ferreira; Barbosa Barquero, Luis Orlando; Alves, José Donizeti; Júnior, Antonio ChalfunUnderstanding what mechanisms are involved in drought response in coffee plants will generate relevant information to assist breeding and/or genetic engineering to obtain new commercial varieties with drought tolerance. This research aimed at studying the effects of drought on leaf water potential, carbohydrate concentrations, and sucrose synthaseand invertase activity in coffee seedlings (Coffea arabica Siriem...
Effect of plant growth regulators on root development in Coffea arabica L. Rubi...
Lacerda, Guilherme Araújo; Chalfun-Júnior, Antonio; Paiva, Luciano Vilela; Melo, Emanuelle Ferreira; Oliveira, Anderson Castro Soares deIt was evaluated the effect of plant growth regulators in the root development in coffee seeds cv. Rubi (Coffea arabica L. Rubi) grown in vitro. Coffee seeds from adult plants were established on medium MS/2 + sucrose (20 g L-1) + agar (6 g L-1). Four treatments were tested: T1 - control; T2 -BAP (6 mg L-1) + NAA (0,1 mg L-1); T3 -BAP (6 mg L-1); T4 - GA3 (5 mg L-1). The highest rooting response was observed on...
