Última Salinity effect on germination and initial growth of seedlings of three forest tree species PFB - Pesquisa Florestal Brasileira Dutra, Tiago Reis; Massad, Marília Dutra; Moreira, Priscila Ribeiro; Ribeiro, Érika Susan Matos. The objective of this work was to evaluate the effect of saline stress on germination and initial growth of canafistula (Peltophorum dubium (Sprengel) Taubert), tamboril (Enterolobium contortisiliquum (Vell.) Morong.) and pau-formiga (Triplaris americana L.), in addition to determining the maximum tolerance to the presence of NaCl in imbibitions solution. A completely randomized design with four replicates of 50 seeds was used in factorial scheme 3 x 5. The response of the three species to five levels of osmotic potentials (0.0; -0.3; -0.6; -1.2 e -1.8 MPa) was evaluate, simulating saline stress with NaCl. At 28 days after sowing, germination percentage; germination speed index (GSI); germination time; root length and root shoot s and total dry mass were...

Ano: 2017 URL: http://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1447 Methods of overcoming dormancy in Schizolobium amazonicum Huber ex Ducke (Leguminosae - Caesalpinioideae) seeds Rev. bras. sementes Cruz,Eniel David; Carvalho,José Edmar Urano de. Seed dormancy is a frequent phenomenon in tropical species, causing slow and non-uniform germination. To overcome this, treatments such as scarification on abrasive surface and hot water are efficient. The objective of this study was to quantify seed germination with no treatment (Experiment 1) and identify an efficient method of breaking dormancy in Schizolobium amazonicum Huber ex Ducke seeds (Experiment 2). The effects of manual scarification on electric emery, water at 80ºC and 100ºC and manual scarification on wood sandpaper were studied. Seeds were sown either immediately after scarification or after immersion in water for 24h in a sand and sawdust mixture. Germination and hard seed percentages and germination speed were recorded and analyzed in a...
