Araucaria angustifolia (Bertol.) O. Kuntze., also known as brazilian-pine, is a forest native species from Brazil. A. angustifolia is more vulnerable to global climate change, considering it is living in cold and humid mountain regions from southern and southeastern Brazil. Among the native Brazilian forest species, it presents one of the greatest growth and genetic gain potential. It shows excellent wood quality and can still be used in human and animal food, presenting great economic, social and environmental value. In order to determine current distribution of the species and better know its habitat, we worked in the regions representing the borders of natural occurrence, identifying populations and getting trees altitude and geographycal position.... |

Imbuya (Ocotea porosa Nees et Martius ex. Nees, Lauraceae) is a species menaced of extinction. In 2003, Embrapa Florestas began a program for its conservation exsitu collecting germplasm at Colombo, Bocaiuva – Paraná state, Canoinhas and Caçador – Santa Catarina state, Brazil. Seeds were immersed in sulphuric acid 70% against dormancy of tegument. Low germination index were obtained, varying from 9,70% to 18,19% (june-october, 2003) due to the sulphuric acid. Inversely, seeds from Bocaiuva and Caçador not submitted to the treatment with sulphuric acid presented germination of 47% and 71%, respectively for these localities. Germination along this period increased from the 6th to the 7th month after sown. Beginning of germination occurred until 200 days... |
