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...
