Hirano, ElcioSementes recalcitrantes de canela fogo (Cryptocaria aschersoniana), canela guaicá (Ocotea puberula), canela imbuia (Nectandra megapotamica), canela sassafrás (Ocotea odorifera) e imbuia (Ocotea porosa), oferecem dificuldades na coleta por apresentarem árvores de grande altura e após a queda natural tem rápida deterioração por insetos. Pela desuniformidade de maturação dos frutos, fazem-se necessárias várias int...
Pre-breeding of Imbuya Populations
Kalil, Antonio Nascim; Lopes, Alexandre Jacobus; Marzollo, Luiz Gustavo; Bortoleto, André Santos; Hirano, Elcio; Sturion, José AlfredoImbuya (Ocotea porosa Nees et Martius ex. Nees, Lauraceae) is a species under extinction of the Mixed Ombrophylous Forest, whose wood owns high economic value. The objective of this work was to discuss precocious individual genetic selection utilizying Selegen REML/BLUP software in germoplasm of Colombo, PR, Canoinhas and Caçador, SC, populations. Results showed that 1182 selected genotypes (42,9 %) were from C...

Kalil Filho, Antonio Nascim; Hirano, Elcio; Sturion, José Alfredo; Sousa, Valderês Aaparecida de; Marzollo, Luiz Gustvo; Nicolotti, FilipeExploitation of imbuya (Ocotea porosa) occurred at the same time of Araucaria angustifolia. Imbuya is threatned of extinction, owns a valuable wood and for these characteristics, Embrapa Florestas, located at Colombo, State of Paraná, Brazil, decided to make efforts for its conservation ex-situ. Collects in Southern Brazil at the localities of Caçador, Canoinhas (State of Santa Catarina), Colombo and Bocaiúva d...

Kalil Filho, Antonio Nascim; Hirano, Elcio; Nicolotti, FilipeImbuya (Ocotea porosa Nees et Martius ex. Nees, Lauracea) is a species of Mixed Ombrophylous Forest threatened of extinction that owns a high quality wood for furniture. Embrapa Florestas is performing imbuya seeds collections for establishing a germplasm bank in october, 2004 in the state of Santa Catarina, Brazil. In spite of its importance, studies about variance components as a basis for phenotypic selectio...

Kalil Filho, Antonio Nascim; Sousa, Valderês Aparecida de; Marzollo, Luiz Gustavo; Hirano, ElcioImbuya (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...
