The aim of present investigations was the increasing of knowledge of the cotton bollworm’s ( Helicoverpa armigera Hbn.) (CB) damages in the different breeding season corns. The damage examinations were made in a 29.2 hectares acreage between Igal and Kazsok villages (Somogy county) on the basis of the flight observation at the end of August 2008. We examined the measure of damages and yield losses based on the collected ears belonging to different breeding season corns (FAO 200–299, FAO 300–399, FAO 400–499, FAO 500–599). The relationship between the breeding season and the damages was examined by variance analysis (one-way anova). The collected samples were examined in analytic laboratory in order to calculate the quantitative alteration of the fundamental in-kernel air dry content values (raw protein, raw fat, starch).Our results proved the significant increasing of damage percentages (FAO 200–299: 8.66%; FAO 500–599: 15.33%), surface damages (cm 2 ) (P = 0.026) and the calculated weight loss of damaged ears (P=0.014) parallel with the increasing of the breeding season length. We confirmed the “forced maturing” in the case of the earlier hybrids in the consequence of the damage. We recorded a decreasing percentage (correlate to the draw matter) of the starch and the raw fat (average decreasing: starch: 1.72; raw fat: 0.26) as well as the increasing starch loss per one hectare, agreeing with the breeding season length increase (starch loss/one hectare: FAO 200–299: 1.54%; FAO 500–599: 2.72%). We observed the quantitative increasing of the raw protein as a function of CB’s damage too, which can be explained by a physiological response to the biotic stress.

The king oyster mushroom (Pleurotus eryngii) is becoming more and more popular amongst the producers due to its excellent taste and relatively easy cultivation technology. Though investigations aiming to involve the mushroom in industrial cultivation had started in Hungary already in the 1950s, significant efforts were not made until 2002. In contrast to this, the volume of production in Europe and the United States has been growing continuously in the last decade. Although the species have been subjected to some taxonomical investigations, there are still a lot of contradictions in the taxonomic positioning of the P. eryngii species complex. In this study we investigated the genetic variability and taxonomic relationships among P. eryngii strains by using the RAPD-PCR method. Fifteen strains were analysed from our collection that represents mostly the Eastern-Hungarian habitats. Twenty-five random decamer primers were tested in the preliminary experiments and six were chosen that were used for binary coding. A neighbour-joining tree prepared from this matrix shows the coherence among the taxonomic relations and production sites of the potentially cultivable Hungarian strains.

This paper deals with a new Gypsophila paniculata dominated half-ruderal Pannonian weed association. In order to identify this vegetation type, samples were compared with some dry and semidry Central European weed associations of Agropyretalia repentis. The community studied seems to belong to the Artemisio-Agropyrion repentis alliance. Based on results, the Gypsophila paniculata dominated dry half-ruderal sand grass stands are classified in the frame of a new association under the name of Gypsophilo paniculatae-Agropyretum repentis . It can be divided into two subassociations, notably a more natural typical one rich in species, replacing disturbed sand grasses → typicum with Artemisia campestris , and another type containing less species and exposed to much stronger disturbance → aperetosum spicae-venti subass. nova.

Abstract  

40 MeV -particles have been used to determine oxygen impurity at ppm levels in silicon, copper, and stainless steel, through the radiochemical separation of18F from the matrix. The separation of18F has been carried out by two techniques, viz.(1) distillation of H2SiF6 and (2) precipitation of KBF4 and some modification has been applied in the separation, depending on the nature of interferences from the matrix. Instrumental approach was also carried out to determine the oxygen impurity at 100 ppm in Si matrix because this approach is not possible in Cu and stainless steel samples due to matrix activity.

Bevezetés: Az utóbbi években felfedezett számos új prognosztikai faktor segítséget nyújthat a várható túlélés meghatározásához krónikus lymphocytás leukémia esetében. Célok: Jelen tanulmány célja e prognosztikai faktorok gyakoriságának, valamint egymással való összefüggésének meghatározása volt 419 beteg mintáin. Módszerek: 160 esetben végezték el az immunglobulin-nehézláncgén mutációs vizsgálatát. Eredmények: Az esetek 62%-ában nem mutált immunglobulin gént találtak, a nehézlánc géncsaládok használata különbözött a mutációs státusz függvényében. A CD38 expresszió 78%-os konkordanciát mutatott a mutációs státusszal, a ZAP-70-expresszió tekintetében korrelációt nem figyeltek meg. Citogenetikai abnormalitást 76%-ban láttak, a leggyakoribb eltérések a del(13q) (57%), a 12-es triszómia (15%), a del(11q) (12%) és a del(17p) (6%) voltak. A del(11q)-t hordozó esetek 95%-a nem mutált, az egyedül del(13q)-t hordozó esetek 74%-a mutált IgH-gént tartalmazott. Következtetések: A vizsgált paraméterek nem függetlenek egymástól, ezért alkalmazásuk a klinikai gyakorlatban gondos tervezést igényel.
