Caracterização morfológica da semente seca e mobilização de reservas durante a ...
Paula, Stelamaris de Oliveira; Sousa, João Alencar de; Brito, Edy Sousa de; Gallão, Maria IzabelInformation about the morphology, chemical composition and reserve mobilization is important in understanding the establishment of native and exotic species. The purpose of this study was to describe the morphology, chemical composition, and mobilization of reserves during germination of noni (Morinda citrifolia L.). Biometric and morphological analyzes were performed with 100 randomly selected dried seeds. Oth...
Ethylene triggers salt tolerance in maize genotypes by modulating polyamine cat...
Freitas, Valdineia Soares; Miranda, Rafael de Souza; Costa, José Hélio; Oliveira, Daniel Farias de; Paula, Stelamaris de OliveiraThe current study was undertaken to investigate if there is a relationship between metabolisms of ethylene and polyamines in the processes of salinity acclimation of salt-tolerant and salt-sensitive maize genotypes. Biphasic ethylene production (at 5.5 and 12.5 h) was registered only in salt-sensitive plants during NaCl exposure. In the salt-tolerant genotype, the unique ethylene peak at 5.5 h was closely relat...
