| 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... |

| Araucaria angustifolia is a species of high economic value, timber, food and to resin but have problems concerning propagation by seed due to the low viability of propagules. The micropropagation may be an alternative for producing seedlings of good quality. The present study evaluated the in vitro establishment of stem segments of A. angustifolia collected in three different positions and in different shifts in culture media and their dilutions. After 60 days of sowing in plastic trays held excision of stem segments of approximately 2-3 cm in length. The experiment was conducted in a completely randomized design, using a 3 x 4 factorial scheme, in which the levels of factor "A" referred to the different collection positions and levels of the factor "B",... |
