Resumo: | Imbuya (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 selection of its characteristics don’t exist. Weight and diameter of seeds collected in two Santa Catarina populations (Canoinhas and Caçador districts) were measured. High repeatability and selective accuracy values were obtained (approximately) for the two characteristics. Predicted phenotypic gains were higher for seed weight than seed diameter. |

Nees, Lauraceae) é uma espécie da Floresta Ombrófila Mista de valor econômico por possuir madeira de alta qualidade para mobiliário de luxo. Acha-se ameaçada de extinção e, por isto, a Embrapa Florestas vem desenvolvendo coletas para a instalação de um banco de conservação de germoplasma em outubro de 2004 em Santa Catarina. Apesar de sua importância, estudos relacionados aos componentes de variância de características das sementes de imbuia (Ocotea porosa) como subsídio à seleção fenotípica de sementes não se acham presentes na literatura. No presente trabalho foram realizadas mensurações do peso e do maior diâmetro de sementes de imbuia das populações de Canoinhas e Caçador, Estado de Santa Catarina para a estimação de componentes de variância e parâmetros de predição. Foram obtidos altos valores de repetibilidade e de acurácia seletiva para as duas características, próximos de 1,0. Maiores ganhos fenotípicos permanentes através de seleção foram obtidos para o caráter peso em relação ao diâmetro da semente via seleção.Embrapa Florestas2004-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1600Pesquisa Florestal Brasileira; n. 48 (2004): jan./jun.; 111-115Pesquisa Florestal Brasileira; No. 48 (2004): jan./jun.; 111-1151983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1600/653Kalil Filho, Antonio NascimHirano, ElcioNicolotti, Filipeinfo:eu-repo/semantics/openAccess2018-03-22T17:55:25Zoai:pfb.cnpf.embrapa.br/pfb:article/1600Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-03-22T17:55:25Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
