Direct seeding of dry forest tree species in abandoned pastures: effects of grass canopy and seed burial on germination. Author(s): GUARINO, E. de S. G.; SCARIOT, A. O. Natural tree regeneration in abandoned pastures can be hampered by various biotic and abiotic filters, including seed removal and predation. We tested the effects of maintenance and removal of grass a... ... Repository: BDPA Publication year: 2014
Consequences of dry-season seed dispersal on seedling establishment of dry forest trees: should we store seeds until the rains? Author(s): VIEIRA, D. L. M.; LIMA, V. V. de; SEVILHA, A. C.; SCARIOT, A. We examined the following hypotheses: (i) seeds of dry forest trees have high pre- and post-germination mortality by desiccation due to the time between seed dispersal and germination and to irregular... ...

Ethanol test to evaluate the physiological quality of forest seeds. Author(s): ORNELLAS, F. L. S.; SOUSA, A. O. de; ARAÚJO, M. do N.; BARBOSA, R. M.; DANTAS, B. F. Rapid tests that allow the assessment of physiological potential are essential parameters for quality seed and seedling production programs. The aim of this work was to establish parameters of a metho... ... Repository: BDPA Publication year: 2022
Bertholletia excelsa Bonpl. seed removal in a primary forest in the Southwest Amazon. Author(s): SILVA, A. C. C. da; WADT, L. H. de O.; KLIMAS, C. Bertholletia excelsa Bonpl. (Brazil nut) is an important extractive resource and one of the main sources of income for many traditional forest communities. The agouti (Dasyprocta spp.) is primarily re... ...

Processing and physical and physiological quality of the native forest seeds of Vernonanthura discolor. Author(s): GRZYBOWSKI, C. R. de S.; SILVA, R. C. da; VIEIRA, E. S. N.; PANOBIANCO, M. The objective was to study the processing of Vernonanthura discolor seeds, evaluating their physical and physiological qualities and defining parameters for purity analysis and determine the weight of... ...

Germination niche of a neotropical dry forest species: seed osmotic stress and recovery. Author(s): SENA, E. M. N. de; SILVA, F. F. S. da; SILVA, J. de J.; GOMES, R. A.; PELACANI, C. R.; DANTAS, B. F. Erythrina velutina Willd is a native Fabaceae with wide occurrence, mainly in the Caatinga Domain with multiple uses. This study aimed to compare the vulnerability/tolerance of seeds of four accession... ... Repository: BDPA Publication year: 2023
Germination test of Cordia trichotoma seeds: a forest species native to Brazil. Author(s): GRZYBOWSKI, C. R. de S.; VIEIRA, E. S. N.; MICHELON, T. B.; PANOBIANCO, M. ABSTRACT: Cordia trichotoma (Vell.) Arrab. ex Steud. is a forest species native to Brazil, naturally propagated by seeds, whose quality assessment may be underestimated by the use of inappropriate met... ...

Climate and seed size of a dry forest species: influence on seed production, physiological quality, and tolerance to abiotic stresses. Author(s): GOMES, S. E. V.; GOMES, R. A.; DANTAS, B. F. Seed production, quality and germination are likely to be affected by a drastic climate change in semi-arid areas predicted for the end of the century. We evaluated Anadenanthera colubrina var. cebil... ... Repository: BDPA Publication year: 2023
Native forest seeds as an income generator within the forest landscape restoration chain. Author(s): PIÑA-RODRIGUES, F. C. M.; EULER, A. M. C.; FREIRE, J. M.; LIMA JUNIOR, M. de J. V.; MENDES, A. M. da S.; SANDIM, A. S. de A.; FRANCO, D. O.; URZEDO, D. I. Repository: BDPA Publication year: 2020
Comparing seed production and regeneration of Carapa guianensis (Aublet.) in two forest types in Acre, Brazil from 2004 to 2007. Author(s): KLIMAS, C.; KAINER, K. A.; WADT, L. H. de O.; RIGAMONTE-AZEVEDO, V.; CORREIA, M. F. Carapa guianensis is a tropical tree valuable for its seed oil and timber. This study compared Carapa seed production and regeneration density in two forest types: upland and occasionally inundated. Repository: BDPA Publication year: 2008
