The results of the monitoring of Thysanoptera species on cultivated plants in Slovenia (2000–2001), Croatia (1994–1996), and
Serbia and Montenegro (1988–2003) are presented in this study. The aim of the investigation was to study the host plant distribution
of the predator Aeolothrips intermedius Bagnall and its potential prey. Banded thrips were found on 30 different host plant species belonging to 16 botanical families,
always in mixed populations with phytophagous or facultative phytophagous insects (including 18 Thysanoptera species). On
the vegetative parts of the cultivated plants, banded thrips were found less numerous in spite of the massive population of
some harmful thrips species. This indicates highly important role of pollen as alternative food for Aeolothrips intermedius. 相似文献

Tetraspanin CD9 is one of the egg membrane proteins known to be essential in fertilization process. The presence and localization of CD9 molecule in spermatozoa and its possible function in reproduction are still unclear. In our study, we describe the localization of CD9 on bull spermatozoa. In the immunofluorescence assay, the positive signal has been observed in the high proportion of sperm cells as a fine grains either on the apical part or through the entire anterior region of sperm head. CD9 recognized by monoclonal antibody IVA‐50 was detected on freshly ejaculated (83.4 ± 3.7%) and frozen‐thawed (84.3 ± 2.3%) sperm. The same reaction pattern was observed on sperm capacitated for 1 h, 2 h, 3 h and 4 h (83.6 ± 2.0%; 84.0 ± 1.5%; 85.7 ± 0.8%; 77.5 ± 10.8%). The presence of CD9 exclusively on plasma membrane of the bovine sperm has been detected by Western blot analysis of the protein fractions after the discontinuous sucrose gradient fractionation of the bull sperm. Moreover, probable role of the sperm CD9 molecule in fertilization process of cattle has been suggested as sperm treatment with anti‐CD9 antibody significantly reduced (by 25%, p ≤ 0.001) the number of fertilized oocytes compared to control group in fertilization assay in vitro. 相似文献

Soil organic carbon (SOC) has a high impact on the sustainability of ecosystems, global environmental processes, soil quality and agriculture. Long-term tillage usually leads to SOC depletion. The purpose of this study was to determine the impact of different land uses on water extractable organic carbon (WEOC) fractions and to evaluate the interaction between the WEOC fractions and other soil properties. Using an extraction procedure at 20°C and 80°C, two fractions were obtained: a cold water extractable organic carbon (CWEOC) and a hot water extractable organic carbon (HWEOC). The results suggest that there is a significant impact from different land uses on WEOC. A lower relative contribution of WEOC in SOC and a lower concentration of labile WEOC fractions are contained in arable soil compared to forestlands. Chernozem soil was characterized by a lower relative contribution of WEOC to the SOC and thus higher SOC stability in contrast to Solonetz and Vertisol soils. Both CWEOC and HWEOC are highly associated with SOC in the silt and clay fraction (<53 µm) and were slightly associated with SOC in the macroaggregate classes. The WEOC fractions were highly and positively correlated with the SOC and mean weight diameter. 相似文献

The objectives of this study were to investigate (i) the correlations between Fusarium head blight (FHB) index, deoxynivalenol (DON) accumulation and percentage of Fusarium‐damaged kernels (FDK) with agronomic and quality traits and (ii) the effect associated with the presence of single QTLs for FHB resistance on agronomic and quality traits in winter wheat. The population was derived from the cross between ‘RCATL33' (FHB resistance derived from ‘Sumai 3’ and ‘Frontana’) and ‘RC Strategy’. Parental lines and recombinant inbred lines (RILs) were genotyped with SSR markers associated with the 3B, 5A and 3A QTLs. The population was planted in FHB‐inoculated nurseries and in agronomy trials. Lines in the 3B QTL class had the lowest FHB index, DON content and FDK level and did not have a significantly lower yield, thousand kernel weight or protein content compared with the lines grouped in other QTL classes (including no QTL class). Marker‐assisted selection of the 3B QTL for FHB resistance into high‐yielding FHB‐susceptible winter wheat is the recommended approach for the development of lines with increased FHB resistance without significant yield and quality penalties. 相似文献

The microscopic analysis of leaflet, petiole, stem and peduncle of 26 populations of 17 Trifolium species was carried out in order to examine their structural characteristics related to digestibility, to compare them between
the populations of forage species and their wild relatives and to evaluate, from histological aspect, the potential of wild-growing
species to be used as forages. Forage species had low proportion of the tissues composed of thick-walled cells and high proportion
of the tissues composed of thin-walled cells in all examined plant parts. The reduction of the proportion of lignified xylem,
sclerenchyma and sclerenchymatous interfascicular parenchyma, were suggested as basic selection criteria in breeding Trifolium species for improved digestibility. T. angulatum, T. medium and T. pannonicum proved to be very similar to the forage species in their histological composition, proportion of thick-walled and thin-walled
cells and type of variation of the examined parameters. We believe that these species have some potential for use as forages
in their own right, but aditional biochemical, physiological and morphological investigations should be conducted. 相似文献

Specific activity of tritium (3H) in precipitation and specific activity of 137Cs in ground-level air were monitored at three locations in Belgrade (Meteorological Station of Belgrade at Zeleno Brdo (ZB), Meteorological Station Usek (USEK), and Vin?a Institute of Nuclear Sciences (VINS)). Data presented cover the period 1985?C1997 for 137Cs for all locations and 1985?C2009 (ZB), 1988?C1997 (USEK), and 1988?C2009 (VINS) for 3H. Concentrations of 3H in precipitation have been determined using electrolytic enrichment and liquid scintillation spectrometer LKB-Wallac 1219 RackBeta. The activity of 137Cs in air was determined on an HPGe detector (Canberra, relative efficiency 23?%). 3H concentrations in precipitation ranged from 0.40?±?0.08 to 74.6?±?5.2?Bq?l?1 decreasing with distance from the nuclear facilities. Significantly higher tritium levels were measured in samples in VINS compared with those from an off-site location. The observed seasonal variations of tritium concentration indicate the stratospheric source of tritium. Increases in activity concentration of 137Cs in the atmosphere were observed after the nuclear plant accident at Chernobyl in April 1986. The concentrations obtained for 137Cs in 1986 were compared with the integrated air concentrations of 137Cs in the region. The increases of 137Cs air concentrations in 1987 and 1988 were attributed to local resuspensions from the ground. Since 1989, the activity level before the accident has been obtained. The average monthly concentrations of 137Cs in ground-level air were shown spread maximum in spring?Csummer period and pronounced maximum during winter. The obtained results were statistically analyzed, i.e., the following parameters were determined: tritium deposition, monthly activities of 3H and 137Cs, seasonal indices, radionuclide loading indices, and linear correlation coefficients. 相似文献

The aim of this study was to identify the prevalence of pathological lesions in pigs from small‐scale farms and to determine associations between pathological lesions and hematological parameters, and carcass and meat quality in slaughtered pigs. The study was conducted on 625 pigs (~115 kg) originating from 20 small‐scale farms. Any signs of pneumonia, pleurisy, pericarditis, and liver milk spots were recorded as present or absent. Complete blood count was investigated. The following carcass quality parameters were measured: live, hot and cold carcass weights, cooling loss, dressing percentage, backfat thickness, and meatiness. Meat pH and temperature were measured 45 min postmortem. Of the 625 examined pigs, 41.8% had pneumonia, 23.5% pleurisy, 2.7% pericarditis, and 29.9% liver milk spots. The presence of pathological lesions in slaughtered pigs adversely affected hematological parameters, reduced live, hot and cold carcass weights, and meatiness and had deleterious effects on meat quality (higher pH45min and higher prevalence of dark, firm and dry meat). In conclusion, this study showed a high prevalence of pathological lesions in slaughtered pigs, indicating serious health problems in smallholder pig production systems. The presence of single and, especially, multiple pathological lesions in slaughtered pigs negatively affected hematological parameters, and carcass and meat quality. 相似文献
