Physical properties of thermally modified juvenile and mature wood of Hevea brasiliensis (Euphorbiaceae)
Calonego, Fred Willians
; Severo, Elias Taylor Durgante ; ; (Floresta e Ambiente, 2020) [Artigo]
Exposing timber to temperatures approaching 200 °C causes thermal modification and changes its characteristics. This study evaluates the effect of various levels of thermal treatment on the physical properties of juvenile ... -
Influence of tree bunching angles on the productivity and costs of a full tree system
Miyajima, Ricardo Hideaki; ; Tonin, Rodrigo Petrongari ; Millani, Thais Maria ; Fenner, Paulo Torres (Scientia Forestalis/Forest Sciences, 2019) [Artigo]
The objective of this work was to evaluate the influence of different angulations of the tree bunching on the time, productivity and costs of a full tree harvesting system composed by a feller-buncher and a skidder. The ... -
Disentangling the effects of genotype and environment on growth and wood features of Balfourodendron riedelianum trees by common garden experiments in Brazil
da Silva, Jane Rodrigues; ; ; ; Marcati, Carmen Regina (Forests, 2020) [Artigo]
Intraspecific studies with populations replicated in different sites allow the effects of genotype and environment on wood features and plant growth to be distinguished. Based on climate change predictions, this distinction ... -
Survival of thermotolerant coliforms in municipal biosolids after application in tropical soil cultivated with Eucalyptus
de Faria, Marianne Fidalgo; Guerrini, Iraê Amaral ; ; ; Passos, José Raimundo de Souza ; ; (Journal of Environmental Management, 2020) [Artigo]
The increasing production of biosolids in urban areas has been led to a search for alternative disposal avenues of this residue, which is rich in organic matter and nutrients. Agricultural land application of biosolids, ... -
Herbicides selectivity on seedlings of White Leadtree (Leucaena leucocephala)
Dias, Roque Carvalho; Gomes, Diego Munhoz ; Anunciato, Vitor Muller ; Bianchi, Leandro ; Carbonari, Caio Antonio ; Velini, Edivaldo Domingues (Cientifica, 2020) [Artigo]
Difficulty in controlling weeds has hindered the success of vegetation recovery projects using white leadtree (Leucaena leucocephala) seedlings in degraded areas. The use of herbicides is indispensable to mitigate damage ... -
Root xylem in three woody angiosperm species is not more vulnerable to embolism than stem xylem
; ; Oya, Thais; Marcati, Carmen Regina ; ; (Plant and Soil, 2020) [Artigo]
Aims: Since plants are compartmentalised organisms, failure of their hydraulic transport system could differ between organs. We test here whether xylem tissue of stems and roots differ in their drought-induced embolism ... -
Savannas after afforestation: Assessment of herbaceous community responses to wildfire versus native tree planting
; ; Cava, Mario G. B.; ; (Biotropica, 2020) [Artigo]
Afforestation and fire exclusion are pervasive threats to tropical savannas. In Brazil, laws limiting prescribed burning hinder the study of fire in the restoration of Cerrado plant communities. We took advantage of a 2017 ... -
Anatomical variation in vascular attributes of wood of Astronium fraxinifolium Schott trees from the soil loan area of a hydroelectric plant and an experimental plantation
Goncalves, Ricardo De Almeida; ; Teixeira De Moraes, Mario Luiz ; Cambuim, Jose ; Martins, Aline Redondo (Flora, 2020) [Artigo]
The survival of plants is linked to their capacity to respond to environmental selection. Plants may show different wood anatomical features related to survival, such as an increase in parenchyma and decrease in diameter ... -
Site index estimation for clonal eucalypt plantations in Brazil: A modeling approach refined by environmental variables
; ; ; ; ; Stape, Jose Luiz (Forest Ecology And Management, 2020) [Artigo]
Growth models have been applied to assess the growth potential for areas without previous forest plantation records and to update forest inventory when commercial stands have been planted. However, there is a lack of growth ... -
The level of relatedness affects self/nonself discrimination in Eucalyptus urophylla seedlings
; ; ; Vieira, Willyam De Lima; (Canadian Journal Of Forest Research, 2020) [Artigo]
Plants can develop differentially because of their ability of self/nonself discrimination and the degree of kinship among them. Here, we evaluate the ability of self/nonself discrimination of Eucalyptus urophylla S.T. Blake ... -
Root parasitism by Scybalium fungiforme Schott & Endl. is not random among host species in seasonal tropical forest
; Dalbeto, Andra Carolina; Francisco, Bruno dos Santos ; ; Munis, Rafaele Almeida ; Engel, Vera Lex ; Durigan, Giselda (Acta Botanica Brasilica, 2020) [Artigo]
Though they comprise 1 % of plant species on the planet, plant parasites are poorly known. They have been considered a threat to cultivated plants and to the conservation of host species in natural areas. Due to the complex ... -
Stand-level growth and yield model system for clonal eucalypt plantations in Brazil that accounts for water availability
; ; ; ; ; ; Stape, Jose Luiz (Forest Ecology And Management, 2019) [Artigo]
Growth and yield (G &Y) model systems aim at forecasting forest productivity. The lack of environmental variables to account for how water availability constrains eucalyptus production in Brazil, however, is argued to be ... -
Screening of Aspergillus, Bacillus and Trichoderma strains and influence of substrates on auxin and phytases production through solid-state fermentation
Prado, Débora Zanoni do; Okino-Delgado, Clarissa Hamaio ; Zanutto-Elgui, Mirella Rossitto ; Silva, Richardson Barbosa Gomes da ; Pereira, Milene Stefani ; ; ; Silva, Magali Ribeiro da ; Velini, Edvaldo Domingues ; Fleuri, Luciana Francisco (Biocatalysis and Agricultural Biotechnology, 2019) [Artigo]
Crop inoculation with microorganisms is an agricultural technique that has been used to stimulate plant growth and development by different mechanisms, such as the production of P solubilizing enzymes, the phytases, and ... -
ATLANTIC BIRD TRAITS: a data set of bird morphological traits from the Atlantic forests of South America
; ; Assis, Julia Camara; Pena, João Carlos Castro ; Muylaert, Renata L. ; Tonetti, Vinicius Rodrigues ; ; Regolin, André Luis ; ; et al. (Ecology, 2019) [Data paper]
