This paper deals with the technological characterisation of Atlas cedar wood from artificial plantation in South Italy. The results indicate that wicking of the probe liquids. ... Cette tendance est la conséquence de la distribution radiale des extractibles qui présentent une concentration maximale dans la zone duramen externe-zone de transition. Considering trees with at least five different specimens, and species with at least 10 different trees, it was possible to investigate within-tree and within-species variability. Burkea africana wächst als laubabwerfender, mittelgroßer Baum und erreicht Wuchshöhen von meist 8 bis zu 12, seltener bis zu 20 Meter. The temperature of 80 °C was chosen, radation of some of the extracts. Le bois de P. Juliflora est dimensionnellement stable et présente des caractéristiques calorifiques, anatomiques et mécaniques normales , mais un taux de cendre élevé. [2] [3] Inga underarter finns listade i Catalogue of Life. E and FN Spon, London, 2000, pp. Spruce wood specimens were vacuum impregnated and afterwards leached according to the prCEN/TS 15119-1, EN 1250-2 and EN 84 procedures. Total phenols, condensed tannins and fla-vonoids contents corroborated phytochemical screening. Burkea africana, the wild syringa (Bambara: siri), is a deciduous, medium-sized, spreading, flat-topped tree belonging to the family Caesalpiniaceae. 15 Hardwoods specificaon and price guide 04 Also known under the name of Bean-Pod TreeZebrawood (En. Siliceous woods identified by silica bodies in anatomy have a very high silica content and only those species deserve a silica study. At species level, variability (quantified by the coefficient of variation) was rather high for density (27%), much lower for lignin and cellulose (14% and 10%) and much higher for ethanol/benzene extractives, hot water extractives and ash content (81%, 60% and 76%). (Pea, bean or legume family). 0000001543 00000 n Soil biologists have long been aware of the importance od the non-pathogenic soil microflora in maintaining soil fertility and soil structure and it, The aim of the present study was to combat wood decay based on the approach controlled-release biocides from polymers. ARE THE PODS AND LEAVES OF PROSOPIS JULIFLORA GROWING IN BARINGO KENYA TOXIC TO LIVESTOCK? Drying for: Burkea africana : Ease of Drying: The wood is reported to dry fairly rapidly and with moderate ease. 0000014109 00000 n Fungal growth inhibition tests using different concentrations of extractives confirmed the fungicidal effects. Contact angles should, therefore, be estimated from the initial part of the immersion, where the secondary wicking can be neglected. Effect of diethylether extracts on growth of wood rotting fungi: Poria placenta (PP), Gloeophyllum trabeum (GT), Coniophora puteana (CP), Coriolus versicolor (CV). Eine Bilanzierung von Einsatzkonzentrationen, Wirkstoffaustrag durch Auswaschung und Restgehalten in der Putzmatrix nach einem Jahr Freibewitterung ergab Bilanzlücken von bis zu 64 %. Gas chromatography-mass spectrometry (GC-MS) analysis revealed compounds in dichloromethane extract different from those obtained with all the other solvents. Variability in the chemical composition of 614 species is described in a database containing measurements of wood polymers (cellulose, lignin and pentosan), as well as overall extraneous components (ethanol-benzene, or hot water extracts and ash, with a focus on silica content). Each leaf is 100350 mm long, with 24 pairs of pinnae and 518 leaflets per pinna. It is not only through copper detoxification and tolerance that the fungus is able to bring about premature wood failure. The effect of extractives on fungal growth showed that extracts weakly inhibited fungal growth up to concentrations of 250 μg/mL but extracts of tali and movingui totally inhibited fungal growth at a concentration of 500 μg/mL. 0000003154 00000 n This work focuses on the influence of extractives during wetting measurements on wood.

For the other wood species, a clear extract was obtained after seven hours indicating that a maximum of colored extractives had been removed. Sterile culture medium (150 mL) prepared from malt (15 g) and, agar (15 g) in distilled water (1 L) was placed in 1 L culture bot, RH to allow colonization of the medium by the mycelium. Results showed that mass losses of non-extracted samples ranged from 0.1 to 59% and those of extracted samples from 3% to 40%. 0000013194 00000 n The Wilhelmy method stems to be a valuable tool for estimating the wetting properties of wood, permitting reproducible measurements of apparent contact angles provided that there is efficient control of wicking and contamination effects. A high value for any extraneous component, even in only one tree, is sufficient to classify the species in respect of that component. Aubréville A., Burkea africana, in: Flore Forestière Soudano- 0000009893 00000 n PROTA4U Record display: PROTA4U Homepage.

CHEMICAL ANALYSIS PERSPECTIVES. 0000008201 00000 n RSA Tree No. From a 30-year-old stand in Sicily 6 trees were selected in order to analyse the natural durability of wood against fungi, according to European Standards, and the main physical and mechanical properties from clear specimens, according to ISO Standards. The results obtained show that in spite of the fungicidal and termiticidal properties of certain products contained in the extracts, these properties do not allow to explain entirely the reasons of the durability. Les extraits brutes acétoniques du duramen sont capables d'inhiber l'activité de E. faecalis (MIC [approximativement égal à] 2.5mg/ml). Further studies are also necessary to identify the products. 23–36. This fact signifi cantly limits use of boron compounds in the field of wood preservation. Sci. is also well-known that few pesticides are sufficiently specific to affect pathogens alone. The Mopane vegetation is signified by Spirostachys africana and the genus Commiphora, while the Lowveld is strongly suggested by eight species: Burkea africana, Ptaeroxylon obliquum, Strychnos sp., Spirostachys africana, Catha edulis, Ficus burkei, Englerophytum magalismontanum and Vepris lanceolata. FTIR spectra of Burkea africana extracts : (a) diethylether extract, (b) acetone extract, (c) toluene/ethanol extract. ABSTRACT The most obvious contamination occurred in the case of measurements on non-extracted veneers immersed in water and formamide. New wood preservatives derived from a greater understanding of wood chemistry may address the demand for more environmentally and socially acceptable products. 6: t. 593–594 (1843). / extract / durability / dimensional stability / wettability, À propos de la durabilité du bois de cœur de, / extrait / durabilité / stabilité dimensionnelle / mouillabi, sterilization (20 min, 120 °C, 1 bar) by addition, kept 15 days in a growth chamber at 20 °C at, is the diameter of the control culture and d, is the dried initial weight of the block and m, Feytaud. 0000011341 00000 n In some cases.

The results are reported in Table III. 0000004837 00000 n University Press, London, 1961, pp. In all, 1,194 trees belonging to 614 species, 358 genera and 89 families were measured. IV). Le duramen est durable vis à vis des champignons et relativement résistant vis à vis des termites. It is suggested that this initial wicking is influenced primarily by the liquid density and structural properties of the specimen (such as porosity and sur face roughness), and not by surface energetics. 1937, p. 612. Leaflets are oval and silvery when they are … An advantage is that high loading of penta in polymer can be achieved. This may also reduce any contamination of the probe liquids by extractives. Drawing: Suzanne Carter. The leaves are the only food resource of two kinds of edible caterpillars which are harvested in thousands during the rainy season, mainly January and February. On the durability of Burkea africana heartwood: evidence of biocidal and hydrophobic properties responsible for durability. 1 H NMR spectra of etheral extract of Burkea africana. It is concluded that the fungus was able to detoxify copper as evidenced by the formation of brown ring during initial stages of decay and growth. 0000004370 00000 n First, when the veneer contacts the liquid, an instantaneous 'initial wicking' occurs. that the penta-bonded acrylate is a poly(ethylene co-dipentachlorophenyl diacrylate), which has a disubstituted pentachlorophenyl group linked through two acrylate ester bonds. ; This species is accepted, and its native range is W.

Percentage of the different wood polymers and GC–MS analysis of wood extractives were carried out to examine correlations between durability and wood chemistry. After extraction, some of the wood samples became vulnerable to fungal attack. Les sucres et surtout les composés phénoliques tels que l’acide gallique et l’acide ellagique ont été identifiés comme composés majoritaires des extraits polaires. The results of the EN 84 and ENV 1250 test are comparable, while the results of the prCEN/TS 15119-1 testing are not in line with the other two methods. Wildesering / Wild Syringa. Before extraction, all wood samples under study were classified as very resistant to fungi attack (class 1) with respect to the standard. Independently, of the nature of the extraction, weight losses observed on, strongly degraded. Wood density is mass of wood per unit volume. Phytochemical screening revealed the presence of several groups of active molecules such as alkaloids, polyphenols, flavonoids, saponins and sterols and/or terpenes in the different extracts. Description. The SEM of wood revealed that the extractives were removed from the fibres. this may result in zero contact angle after a certain immersion depth. After extraction, the solvent was evaporated under reduced pressure (or lyophilized in the case of water) and the crude extract was dried under vacuum in a desiccator over phosphorus pentachloride, P 2 O 5 , weighed and stored in the dark for further use. Extracts obtained with acetone and toluene/ethanol mixture (2/1, v/v) indicated the presence of few amounts of fatty acids and sugars, catechin in small amount and huge amounts of phenolic acids like gallic and ellagic acids. 2009 ). Range. The dichloromethane extracts had a very low antioxidant activity, while acetone and toluene/ethanol extracts presented EC 50 values similar to those of catechin and BHT used as reference antioxidant compounds. Torn grain on planed surfaces is common. The capacity of extracts to inhibit the fungal growth was evaluated at different concentrations with propiconazole (a commercial fungicide for wood) as standard. Wilhelmy method, Part 2, Holzforschung 55 (2001) 33–41. The species grows naturally in open, wooded grassland and open woodland (Maroyi, 2010;Tanko et al., 2011) on sandy soil and lower slopes on rocky hills in the high rainfall areas, occasionally in miombo woodland (Mulofwa et al., 1994). Indeed, wood humidity measured after, 16 weeks is lower than 30%, which could create unfavourable, conditions approaching the 22% reported in the literature as, being necessary to the good development of most wood rotting, beech wood (compare 62° to 0°, Tab.
