ABSTRACT: The ex situ conservation of recalcitrant seeds has been one of the biggest challenges in seed technology. Different strategies have emerged in recent years and among these strategies, osmotic conditioning at controlled temperatures has show

ABSTRACT: Analyzing unripe phases of orthodox seeds and the variations in traits depending on environmental conditions under which they were formed is a way of gaining knowledge on the differences and similarities between orthodox and recalcitrant se

Abstract: The modification of atmosphere composition is a strategy to prolong the storage of organisms susceptible to senescence. Atmospheres with high levels of carbon dioxide could be applied to prolong the viability of recalcitrant seeds, which ar

Abstract: Seeds of the genus Eugenia have high regenerative capacity, producing roots and shoots from seeds with reduced cotyledon matter. In addition, seeds of this genus regenerate new roots and shoots when the first roots and shoots are eliminated

Abstract: Seeds of the genus Eugenia L. (Myrtaceae) have interesting propagation strategies, and the reactive oxygen species (ROS) seem to be related to their germination and seedling production. In this study, the effects of ROS on the germination o

Abstract: The reduction in humidity and temperature makes it possible to prolong the storage of seeds, except for those sensitive to desiccation (recalcitrant), which therefore cannot be included in ex situ conservation banks. One way to control the

Abstract: Seed pathology is an area of study that began in the last century and has been developing since then, with increasing contribution especially to agricultural production systems. However, in the environmental area, studies began much later,

Abstract: Studies on seed germination in Eugenia species after embryo fractionation have demonstrated that cotyledon cells have capacity for de-differentiation and consequent production of roots. However, there is no information about the origin of t

RESUMO (Taxas respiratórias de sementes de Eugenia brasiliensis Lam. (Myrtaceae) sob atmosferas modificadas). O sucesso da conservação de sementes se resume à redução tanto do seu metabolismo quanto de outros organismos associados a elas. Uma d

ABSTRACT: Recalcitrant seeds are sensitive to desiccation and low storage temperatures, but there is a gradient of recalcitrance between different species and between populations of the same species. Therefore, tolerance to drying and low temperature
