Amburana cearensis (Fr. Allem) AC Smith is a native Caatinga species commonly found in the semiarid region of North East of Brazil, which possesses resistance to temperature and drought stress and is widely used in the folk medicine. This study aimed at a better understanding of seed imbibition and germination as well as to evaluate the effect of water(More)
Jatropha curcas is an oil-rich Euphorbiaceae seed species renowned for its apparent tolerance to environmental stresses. It is considered a promising source of renewable feedstock for biodiesel production in the Brazilian semiarid region where crop establishment requires a better understanding of the mechanisms leading to proper seed and plant behavior(More)
This study aimed to evaluate the effects of priming on seed germination under salt stress and gene expression in seeds and seedlings of P. angulata L. After priming for 10 days, seed germination was tested in plastic trays containing 15 ml of water (0 dS m-1 - control) or 15 ml of NaCl solution (2, 4, 6, 8, 10, 12, 14 and 16 dS m-1). Fresh and dry weight of(More)
Ricinus communis is becoming an important crop for oil production, and studying the physiological and biochemical aspects of seedling development may aid in the improvement of crop quality and yield. The objective of this study was to assess the effect of temperature on biomass allocation in two R. communis genotypes. Biomass allocation was assessed by(More)
Resumption of DNA synthetic activities and β-tubulin accumulation was studied in embryo organs of germinating cucumber (Cucumis sativus L.) seeds. Flow-cytometric analysis indicated the existence of 2C, 4C, and 8C nuclei in the radicle of mature embryos, whereas in cotyledons most of the cells contained nuclei with 2C DNA content. Upon imbibition of water,(More)
Seed development and germination are characterized by an arrest and a resumption of growth, respectively. Evidently, the cell cycle plays an important role in these events. Tomato (Lycopersicon esculentum) is one of the best studied dicot species with respect to the role of the cell cycle in seed development, germination and dormancy. Developmental arrest(More)
