Paiva, Emanoela Pereira de; Torres, Salvador Barros; Oliveira, Renata Ramayane Torquato; Sá, Francisco Vanies da Silva; Leite, Moadir de Sousa

Salvia hispanica seedlings have stood out for their potentialities in nutrients for agri-food industries. Nevertheless, studies related to this species are still scarce, especially with respect to agronomic factors that enable its propagation and development. Hence, this study aimed to evaluate germination, vigor and osmotic adjustment of S. hispanica seeds and seedlings subjected to water and thermal stress. T...

Water deficit on germination and vigour in seeds of the Jambu

Sarmento, Erivanessa Costa Sousa; de Oliveira, Fernando Sarmento; dos Santos, Brenna Rafaella Verissímo; Torres, Salvador Barros

Water availability influences plant metabolism during the various stages of development, especially in the period between germination and seedling emergence. The aim of this study was to evaluate the effect of water deficit during the germination process on seeds of A. oleracea. The experiment was carried out in a completely randomised design, with four replications of 50 seeds. The treatments were arranged in ...

Vigor determination of okra seeds by respiratory activity

Leite, Moadir de Sousa; Torres, Salvador Barros; de Freitas, Rômulo Magno Oliveira; Nogueira, Narjara Walessa; Leite, Tiago de Sousa

Seed companies increasingly need to obtain reliable results on seed vigor. Therefore, the objective was to verify the efficiency of the respiratory activity measurement, by the CO2 released, to classify the vigor of okra seed lots. For this, five seed lots of okra cv. "Santa Cruz 47" were used. In order to determine seed physiological quality, the following tests were performed: germination, seedling emergence,...
