Mimetic seeds simulate the appearance of fleshy fruits and arilled seeds without producing nutritive tissues as a reward for seed dispersers. In this strategy of seed dispersal, seeds may remain attached to the mother plant ...

Dormancy is a physiological process that allows seeds to survive in unfavorable environments by preventing their germination. For a large number of species, seed desiccation at the end of maturation is common, and for some ...

Seeds of Bixa orellana (L.) have a sclerified palisade cell layer, which constitutes a natural barrier to water uptake. In fact, newly fully developed B. orellana seeds are highly impermeable to water and thereby dormant. ...

Flammable ecosystems host plants with different strategies in response to fire, such as increasing germination after the exposure to smoke and dormancy breaking by heat shocks. Cerrado is a fire-prone ecosystem, but less ...

– Species that produce seeds with a rigid integument represent a serious problem because their impermeable coat restricts the entry of water, which makes germination difficult. The heteromorphism of the integument in ...

Impermeabilidade do tegumento da semente à água ocorre em muitas espécies, inclusive em Schizolobium amazonicum Huber ex Ducke. Para promover a germinação de sementes com tegumento impermeável um dos métodos recomendados ...

Este trabalho objetivou avaliar diferentes períodos de imersão de sementes de saguaraji-vermelho (Colubrina glandulosa) em ácido sulfúrico, para a superação da dormência. O experimento foi dividido em duas etapas. Na ...
