No. of bitstreams: 0 Previous issue date: 2022-01-01; Loblolly pine (Pinus taeda L.) is widely used for forestry in southern Brazil, with most seeds coming from clonal seed orchards. This study investigated the effects of previous land use on the adaptability, stability, and productivity of loblolly pine progenies in southern Brazil, aiming to produce a se...
Effect of provenances on wood properties of balfourodendron riedelianum
Assad, Amanda Aparecida Vianna; Ballarin, Adriano Wagner [UNESP]; Freitas, Miguel Luiz Menezes; Longui, Eduardo LuizMade available in DSpace on 2022-05-01T00:03:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-31; Universidade Estadual Paulista; Wood is comparatively more conservative than other parts of trees, such as leaves, which present greater phenotypic plasticity. We studied the effect of seed origin on annual increment, physical-mechanical properties and anatomical characteristics of Balfourodendron riede...
Effect of soil type on wood chemical constituents and calorific values of 33-ye...
De Lima Vieira, Willyam [UNESP]; Amorim, Erick Phelipe; Freitas, Miguel Luiz Menezes; da Silva Júnior, Francides Gomes; Guerrini, Iraê Amaral [UNESP]Made available in DSpace on 2022-05-01T11:54:03Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Red Latosol (LV), Red Nitosol (NV) and Quartzarenic Neosol (RQ) have different physical and chemical characteristics, as well as water holding capacity. This study aimed to determine how such differences cause changes in wood density, extractives, lignin and holocellulose contents, as well as higher hea...
Effect of soil type on mean annual increment, wood anatomy and properties of 33...
Vieira, Willyam de Lima; Amorim, Erick Phelipe; Correa, Caio Corsato; Yamaji, Fabio Minoru; Freitas, Miguel Luiz Menezes; Ballarin, Adriano WagnerThis study aimed to determine the effects of physical, chemical and water-holding capacity of Quartzarenic Neosol, Red Latosol and Red Nitosol on tree growth, physicomechanical properties and anatomical features of wood from 33-year-old C. citriodora plantations. More clayey soils with higher water availability, such as Red Latosol and Red Nitosol, increased the mean annual increment and heartwood percentage. I...

Estabelecimento de mudas de Eucalyptus spp. e Corymbia citriodora em diferentes...
Oliveira, Karina Fernandes; Souza, Anderson Marcos de; Sousa, Glauce Taís de Oliveira; Costa, Ana Luiza Moreira da; Freitas, Miguel Luiz MenezesO presente trabalho objetivou avaliar a qualidade de mudas de seis espécies de eucalipto, produzidas em substratos com diferentes proporções dos resíduos orgânicos: fibra de coco e casca de arroz carbonizada. O experimento foi implantado no Viveiro Florestal da UnB. Como substratos, foram utilizados os dois resíduos misturados à vermiculita em três proporções (25%, 50% e 75%). As espécies foram avaliadas separa...
VARIABILIDADE GENÉTICA E GANHOS DE SELEÇÃO EM PROGÊNIES DE Myracrodruon urundeu...
Pupin, Silvelise; Freitas, Miguel Luiz Menezes; Canuto, Daniela Silvia de Oliveira; Silva, Alexandre Marques da; Marin, Ana Lilia AlzateA exploração inadequada de madeiras nativas têm provocado à redução de populações naturais, como foi o caso da Myracrodruon urundeuva. Os objetivos deste trabalho foram estimar parâmetros genéticos para caracteres silviculturais, em um teste de progênies de M. urundeuva, em sistema de plantio multi-espécie e avaliar o potencial para conservação ex situ e transformação em um pomar de sementes por mudas. O experi...
