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 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 ...
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,...

Pithecellobium dulce destaca-se por apresentar potencial madeireiro e forrageiro, além de diminuir o risco de erosão do solo, aumentar a fixação de nitrogênio e possuir propriedades medicinais. A profundidade e a posição de semeadura são fatores importantes dentro do processo de germinação por garantir um desenvolvimento rápido e uniforme das plântulas. O objetivo deste estudo foi avaliar a influência da posiçã...
Mimosa tenuiflora Willd., popularly known as jurema-preta, is an arboreal species of great importance for the brazilian Northeast due to its uses as a medicinal plant and in the restoration of degraded soils. No information is available in the Rules for Seed Analysis and the Instructions for Seed Analysis of Forest Species regarding ideal conditions for of this species. Thus, this study aimed at evaluating the ...
O objetivo deste trabalho foi verificar a qualidade sanitária de sementes salvas de feijão-caupi (Vigna unguiculata L. Walp.) coletadas no estado do Rio Grande do Norte. Para isso, 37 amostras de sementes salvas de feijão-caupi foram coletadas de diferentes municípios e comparadas com sementes básicas, variedades Guariba e Pujante, oriundas do campo de produção de sementes básicas da Embrapa Produtos e Mercado...
