| This research had as main objectives the evaluation of cedar’s seeds seed-borne fungi and the Fusariumsp. and Pestalotia sp. pathogenicities. For the fungi detection Potato Dextrose and Agar medium and Blottertest methods were used. For the pathogenicity tests, isolates of Fusarium sp. and Pestalotia sp. were used. The following fungi were observed: Pestalotia sp., Fusarium sp., Phomopsis sp., Colletotrichum sp., Macrophomina sp. and Cladosporium sp. The fungi observed in the highest frequencies were: Fusarium sp., Phomopsis sp. and Pestalotia sp. A reduction of the germination level was observed in seedlings from cedar’s seed inoculated with Fusarium sp. doi: 10.4336/2009.pfb.58.81 |

| The aim of the study was to evaluate the initial development of different provenances and the influence of base fertilizer and coverage on growth of Cedrela fissilis seedlings. Provenances of seeds were collected in Lapa, PR, Fernandes Pinheiro, PR and Itaara, RS. After germination, the seedlings were transplanted to plastic bags of 500 cm³, filled with commercial substrate. Total height (h), stem diameter (sd), and ratio h/sd seedlings were measured after 150 days of transplanting. Seedlings of Fernandes Pinheiro received basic fertilization after transplantation (0, 2, 4, 6 and 8 g dm-3 Osmocote®) and cover (3 and 6 g L-1, respectively, of Peter’s® and urea). The provenance and doses of controlled-release fertilizer influenced early development... |
