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
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
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
Pollen and seed flow patterns of Carapa guianensis Aublet. (Meliaceae) in two types of Amazonian forest. Author(s): MARTINS, K.; RAPOSO, A.; KLIMAS, C. A.; VEASEY, E. A.; KAINER, K.; WADT, L. H. de O. Various factors affect spatial genetic structure in plant populations, including adult density and primary and second-ary seed dispersal mechanisms. We evaluated pollen and seed dispersal distances an... ... Repository: BDPA Publication year: 2012
Rainfall, not soil temperature, will limit the seed germination of dry forest species with climate change. Author(s): DANTAS, B. F.; MOURA, M. S. B. de; PELACANI, C. R.; ANGELOTTI, F.; TAURA, T. A.; OLIVEIRA, G. M.; BISPO, J. S.; MATIAS, J. R.; SILVA, F. F. S.; PRITCHARD, H. W.; SEAL, C. E. Drylands are predicted to become more arid and saline due to increasing global temperature and drought. Although species from the Caatinga, a Brazilian tropical dry forest, are tolerant to these condi... ... Repository: BDPA Publication year: 2020
Hydropriming changes temperature thresholds for seed germination of tree species from the Caatinga, a Brazilian tropical dry forest. Author(s): NASCIMENTO, J. P. B.; DANTAS, B. F.; MEIADO, M. V. This study evaluates the effects of hydration and dehydration cycles (HD cycles) on seed germination of four Caatinga tree species (Anadenanthera colubrina var. cebil, Enterolobium contortisiliquum, P... ...

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... ... Repository: BDPA Publication year: 2022
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
