<p class="p1">A Nyugat-magyarországi Egyetem „Alacsony sűrűségű faanyag fiziko-mechanikai és felületfizikai tulajdonságainak komplex elemzése” címmel (azonosító: K116-216), Országos Tudományos Kutatási Alapprogram pályázatot nyert, melynek keretein belül a hazai nyárfa és különös tekintettel a Pannónia nyár (<em>Populus x euramericana cv. Pannónia</em>) állományok felmérésére és sokrétű vizsgálatára kerül sor. A pályázat fő célja a hazai, különböző termőhelyekről származó, ültetvényes nyár faanyag szerkezeti felhasználásának előkészítésére elvégzett anatómiai, mechanikai és felületfizikai vizsgálatok elvégzése. A pályázat első fél évében a hazai releváns irodalmak feltárására koncentráltunk annak érdekében, hogy a terepi munkák megkezdéséhez szükséges információkkal rendelkezzünk. A publikációk feltárásakor a hazai releváns publikációk megismerése volt a cél, amely során a szaporítóanyag aktuális helyzete, az erdősültségi szempontok, a nyártermesztés, valamint az anatómiai és szerkezeti tulajdonságok tekintetében közölt publikációk, felmérések, kutatási eredmények feldolgozását végeztük el.</p>

Candidate Clone

Growth vigor of 7 poplar clones was researched, i.e. 5 candidate clones for registration (B-81, B-229, PE 19/66, 182/81 and 129/8) and 2 clonal cultivars (1-214 and "Pannonia") which had been registered earlier. The taxonomy of the study poplar clones was as follows: B-81 (Populus deltoides), B-229 (Populus deltoides), PE 19/66 (Populus deltoides), 182/81 (Populus deltoides), 129/81 (Populus x euramericana), 1-214 (Populus x euramericana) and "Pannonia" (Populus x euramericana). The research was performed in three field experiments established in 2002 on the area of the Forest Estate Sremska Mitrovica. Although the experiments were established with several planting spaces, the first information indicate that the candidate clone PE 19/66 had the greatest vigor on the optimal soil types (humofluviosol and fluvisol loamy form), while the candidate clone B-81 had the advantage on the less favored soil type (meadow black soil on loess alluvium). Based on the attained diameters and heights, it can be concluded that these are the successfully established plantations and that the candidate clones showed significant genetic potentials, which points to the fact that in future the production of poplar wood volume can be significantly increased.

The observation of small magnetic materials is one of the most important applications of electron holography to material science, because interferometry by means of electron holography can directly visualize magnetic flux lines in a very small area. To observe magnetic structures by transmission electron microscopy it is important to control the magnetic field applied to the specimen in order to prevent it from changing its magnetic state. The easiest method is tuming off the objective lens current and focusing with the first intermediate lens. The other method is using a low magnetic-field lens, where the specimen is set above the lens gap.Figure 1 shows an interference micrograph of an isolated particle of barium ferrite on a thin carbon film observed from approximately [111]. A hologram of this particle was recorded by the transmission electron microscope, Hitachi HF-2000, equipped with an electron biprism. The phase distribution of the object electron wave was reconstructed digitally by the Fourier transform method and converted to the interference micrograph Fig 1.

Adhesion Process

The aim of this study was to evaluate the influence of anatomical characteristics on the adhesion performance of Vatairea sp., Paulownia sp., Aspidosperma populifolium and Tectona grandis wood. Specimens for anatomical, physical and mechanical analyzes were produced from tangentially oriented boards. The treatments were joint glued from pieces of the same anatomical orientation (radial and tangential), evaluated for shear strength and glue line failure. The Vatairea sp wood had the highest specific gravity (0.74 g cm-3) and the Paulownia sp (0.34 g cm-3) wood was smaller. Aspidosperma populifolium species showed the highest shear strength in the glue line in the tangential and radial faces. The anatomical variables with higher influence on the wood adhesion process were pith ray cells and especially fibers that exhibit the greatest correlation with the shear strength of the glue line.
