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
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... ...
