1. Adsorption/desorption characteristics and enrichment of quercetin, luteolin and apigenin from Flos populi using macroporous resin
Abstract In this study, the adsorption/desorption characteristics of quercetin, luteolin and apigenin from Flos populi extract (Populus tomentosa Carrière, Salicaceae) on twelve macroporous resins (NKA-9, HPD-600, HPD-826, HPD-750, HPD-400, DM-130, AB-8, SP-825, X-5, D-101, HPD-100, HPD-200) were evaluated. Both high adsorption and desorption capacities of

2. Artificial diet for laboratory rearing of Condylorrhiza vestigialis (Guenée, 1854) (Lep.: Crambidae)
ABSTRACT The Brazilian Poplar Moth, Condylorrhiza vestigialis (Guenée), compromises the wood productivity of poplar trees (Populus sp.), mainly affecting the matchstick industry in southern Brazil. Considering the lack of information on rearing techniques for this insect, the objective of this study was to develop an artificial diet to rear C. vestigialis w

3. Efficiency of treatments for controlling Trichoderma spp during spawning in cultivation of lignicolous mushrooms
Trichoderma spp is the cause of the green mold disease in mushroom cultivation production. Many disinfection treatments are commonly applied to lignocellulose substrates to prevent contamination. Mushroom growers are usually worried about the contaminations that may occur after these treatments during handling or spawning. The aim of this paper is to estimat

5. Biodegradation of naphthalene and anthracene by chemo-tactically active rhizobacteria of populus deltoides
Several naphthalene and anthracene degrading bacteria were isolated from rhizosphere of Populus deltoides, which were growing in non-contaminated soil. Among these, four isolates, i.e. Kurthia sp., Micrococcus varians, Deinococcus radiodurans and Bacillus circulans utilized chrysene, benzene, toluene and xylene, in addition to anthracene and naphthalene.

6. Primeiro relato da ocorrência de Septoria musiva em álamo no Brasil
O fungo Septoria musiva foi isolado de plantas de álamo com sintomas de mancha foliar e cancro no caule, nos estados do Paraná e Santa Catarina, Brasil, em 2004. Testes de patogenicidade e subseqüente reisolamento de Septoria musiva confirmaram a hipótese de que este fungo era o agente causal da doença. Este é o primeiro relato de Septoria musiva em á

9. Compactación inducida por el tráfico de máquinas en suelo forestal
Field test were carried out with the objective of evaluating the wood harvest and extraction traffic effects on soil physical properties on a commercial poplar plantation (Populus sp.). Two situations were evaluated: a) non-transited zones and b) transited zones by the harvest machinery. Penetration resistance, bulk density and gravimetric moisture were dete

10. Molecular Genetics of Rust Resistance in Poplars (Melampsora Larici-Populina Kleb/Populus Sp.) by Bulked Segregant Analysis in a 2 X 2 Factorial Mating Design
With random amplified polymorphic DNA (RAPD) markers, we have tagged a genomic region in Populus sp. involved in qualitative resistance to Melampsora larici-populina. Our approach was based on three steps: use of RAPD markers that can be quickly and efficiently researched; application of ``bulked segregant analysis'' technique on individuals of one interspec

11. Cellulose in Cyanobacteria. Origin of Vascular Plant Cellulose Synthase?
Although cellulose biosynthesis among the cyanobacteria has been suggested previously, we present the first conclusive evidence, to our knowledge, of the presence of cellulose in these organisms. Based on the results of x-ray diffraction, electron microscopy of microfibrils, and cellobiohydrolase I-gold labeling, we report the occurrence of cellulose biosynt

12. Biodegradation of Nitro-Substituted Explosives 2,4,6-Trinitrotoluene, Hexahydro-1,3,5-Trinitro-1,3,5-Triazine, and Octahydro-1,3,5,7-Tetranitro-1,3,5-Tetrazocine by a Phytosymbiotic Methylobacterium sp. Associated with Poplar Tissues (Populus deltoides × nigra DN34)
A pink-pigmented symbiotic bacterium was isolated from hybrid poplar tissues (Populus deltoides × nigra DN34). The bacterium was identified by 16S and 16S-23S intergenic spacer ribosomal DNA analysis as a Methylobacterium sp. (strain BJ001). The isolated bacterium was able to use methanol as the sole source of carbon and energy, which is a specific attribut
