1. Effect of canopy cover on development of cedar (Cedrela fissilis) and aspects of damage caused by Hypsipyla grandella in agroforestry system
Resumo Cedrela fissilis (Vell.) é uma importante espécie madeirável nativa da América do Sul que sofre frequente pressão do extrativismo ilegal. As iniciativas de cultivo comercial acumulam fracassos recorrentes pela ação da broca-do-cedro Hypsipyla grandella (Zeller, 1848). Um dos métodos de manejo utilizados para reduzir os ataques é o plantio em

2. Exigência nutricional e produtividade em minijardim clonal de Toona ciliata var. australis
Resumo O estado nutricional da planta-matriz é imprescindível para a manutenção do seu vigor vegetativo, fundamental para a produção de miniestacas. Portanto, o fornecimento de nutrientes em quantidades ideais durante o manejo das minicepas influencia o sucesso da propagação. Objetivou-se com este estudo avaliar e comparar a produtividade do minijard

3. Biological Resistance of Two Reforestation Woods to Dry Wood Termites
ABSTRACT This work aimed to evaluate the biological resistance of Australian red cedar (Toona ciliata) and Eucalyptus woods to the Cryptotermes brevis (Kalotermitidae) dry wood termite species. The species used to evaluate natural resistance to insect attacks were Australian red cedar from 6 and 12-year-old plantations installed in the mountainous region of

4. A Comparative Study on Chemical Composition, Antileishmanial and Cytotoxic Activities of the Essential Oils from Leaves of Guarea macrophylla (Meliaceae) from Two Different Regions of São Paulo State, Brazil, Using Multivariate Statistical Analysis
Meliaceae representatives are economically important in several aspects including the production of highly prized woods (mahogany, cedar, etc.), constituents for cosmetics, and insecticides. The present study aimed to verify the chemical composition as well as leishmanicidal and cytotoxic potential of essential oils from leaves of two different populations o

5. First report of Hypsipyla grandella (Lepidoptera: Pyralidae) on African mahogany Khaya ivorensis
ABSTRACT The mahogany shoot borer Hypsipyla grandella Zeller is an important economic pest in all American tropical forests, because it prevents monoculture of valuable timber trees species like mahogany and cedar. The shoot borer damages several tree structures, especially the apical shoots, impairing the formation of the commercial stem. This pest can atta

6. AVALIAÇÃO DE ESPECTRÔMETRO NIR PORTÁTIL E PLS-DA PARA A DISCRIMINAÇÃO DE SEIS ESPÉCIES SIMILARES DE MADEIRAS AMAZÔNICAS
Supervising wood exploitation can be very challenging due to the existence of many similar species and the reduced number of wood identification experts to meet the demand. There is evidence that valuable endangered wood species are being smuggled disguised as other species. Near infrared spectroscopy (NIRS) and chemometrics has been successfully used to dis

7. Characterization of Turkish honeys regarding of physicochemical properties, and their adulteration analysis
Abstract This work was conducted to evaluate the quality of 54 honey samples from eighteen different origins from Turkey. Physicochemical properties were examined according to AOAC methods, total phenolic and flavonoid contents by a spectrophotometric method and authenticity of honeys by Combustion Module - Cavity Ring-Down Spectroscopy (CM-CRDS). The micros

8. Toona ciliata genotype selection with the use of individual BLUP with repeated measures
The increasing demand for raw material for multiple uses of forest products and by-products has attracted the interest for fast growing species, such as the Australian Cedar (Toona ciliata), which presents high productive and economic potential. This study aimed at estimating genotypic parameters and values for the species through the use of the BLUP procedu

9. Matéria orgânica e atributos químicos em solo de tabuleiros costeiros sob diferentes coberturas vegetais / Organic matter and chemical attributes of an Coastal Tableland soil under different vegetation covers
The conversion of native vegetation in agricultural and forest crops results in changes in soil properties. The aimed was to assess the dynamic attributes of a Yellow Oxisol under differents vegetation covers in the Coastal Tableland. Soil samples were collected at depths of 0-10, 10-20 and 20-40 cm in June 2011 in Sooretama, ES, considering four soil vegeta

10. Dendrocronologia, fenologia, atividade cambial e qualidade do lenho de árvores de Cedrela odorata L., Cedrela fissilis Vell. e Schizolobium parahyba var. amazonicum Hub. ex Ducke, no estado do Acre, Brasil / Dendrochronology, phenology and cambium activity and quality of the wood trees of Cedrela odorata L., Cedrela fissilis Vell. and Schizolobium parahyba var. amazonicum Hub. ex Ducke, in Acre state, Brazil
O estado do Acre possui uma vocação eminentemente florestal, devido a alta abundância natural de espécies madeireiras em um ecossistema caracterizado pela biodiversidade de espécies tropicais. Pesquisas em dendrocronologia nessa região tropical indicam que 35-50% das espécies arbóreas formam anéis de crescimento. Neste sentido, a dendrocronologia, m

11. Equações de biomassa e estoques de carbono de seis espécies em plantios mistos no noroeste do Mato Grosso
During this time of discussion about global warming and climate change, environmental restoration projects thought as a CO2 sink in its plant biomass are essential in the fighting the increasing concentration of global warming greenhouse gases. One very eficient method to sequester atmosphere carbon is through reforestation and quantifying the resulting stan
