Erratum: Chemical composition of cabbage (Brassica oleracea L. var. capitata) grown on acid sulfate soils     

Rasmus Fältmarsch  Peter Österholm 《植物养料与土壤学杂志》2010,173(5):795-795

The purpose of this study was to investigate the influence of soil geochemistry on the concentrations of Ca, K, Mg, P, Co, Ni, Zn, Mn, Cu, and Fe in cabbage (Brassica oleracea L. var. capitata) grown on acid sulfate (AS) soils in Western Finland. A total of 11 topsoil (0–20 cm) and corresponding cabbage samples and three whole‐soil profiles (≈ 0–260 cm) were collected on three agricultural fields. The concentrations of Co and Zn in cabbage were correlated with the NH₄Ac‐extractable (easily available) concentrations in the topsoil, indicating that the uptake of these elements in cabbage is largely governed by soil geochemistry. Yet, the concentrations of Co and Zn in cabbage were not in general elevated relative to that of Finnish average values, although some AS soils showed enriched concentrations of these metals in the soil and cabbage. Significant geochemical differences (e.g., oxidation depth, organic‐matter and S content, pH) were observed among the studied AS soils, while, on the other hand, the concentrations of Ca, K, Mg, P, Ni, Mn, Cu, and Fe in cabbage were relatively similar. The hydroxylamine‐extractable concentrations of these elements in the topsoil were not correlated to those in cabbage, suggesting that uptake is not governed by the oxide‐bound fraction of these elements in the soil. Similarly, the easily available concentrations of Ca, P, Ni, Mn, Cu, and Fe in the topsoil were not correlated to those in cabbage, indicating that uptake is independent of the easily available concentrations in the soil. Hence, it is suggested that cabbage can regulate and thus optimize its concentrations of Ca, P, Ni, Mn, Cu, and Fe. Oxidation depth affected neither the easily available concentrations of Co, Ni, Zn, and Mn in the topsoil nor the concentrations in cabbage. However, the subsoil with a lower oxidation depth, which is to a smaller extent affected by leaching, may partly be enriched in these metals. Nevertheless, these showed no increased concentrations in cabbage. Based on these findings, it is suggested that the large amounts of metals mobilized in AS soils are easily lost to drains, subsequently contaminating nearby waterways and estuaries whereas they are only partly enriched in cabbage and other previously studied crops (oat).  相似文献   

Slope length effects on microbial biomass and activity of eroded sediments   总被引：2，自引：0，他引：2  

Ömer Kara  Hüseyin Şensoy  İlyas Bolat 《Journal of Soils and Sediments》2010,10(3):434-439

Purpose  

Due to climatic and topographic conditions, soil erosion is a major problem in Turkey; approximately 86% of the land is suffering from some degree of erosion. This study investigated the relationship between bare soil slope length and the erosion-induced degradation of soil quality and the loss of carbon (C) and nitrogen (N) from the microbial biomass in eroded sediment in the Western Black Sea Region of Turkey.  相似文献

Phyllonorycter apparella, a new record and a new pest of trembling aspen (Populus tremula) in Turkey     

Göksel Tozlu  Rüstern Hayat  Hikmet Özbek 《Phytoparasitica》2002,30(1):38-42

Phyllonorycter apparella (Herrich-Schäffer, 1855) (Lepidoptera: Gracillariidae) is a new record for the Turkish fauna and a new trembling aspen(Populus tremula L.) pest for Turkey. Its biology, damage and infestation ratio were studied in Sankami?. (Kars), Turkey, during 1996 and 1997.P. apparella has one generation a year. The developmental stages of the pest are described briefly. P.apparella hibernates in the adult stage. At the beginning of June, the adults appear. Females deposit their eggs on both leaf surfaces, generally one by one, 7–10 days after emerging. The early instars (sap-feeding larvae) start to mine mostly from the underside of leaves. Each mine has one larva, and each leaf may have up to 26 mines. The last instar (tissue-feeding larva) begins to pupate in the mine after mid August. The adults emerge from mid September to the beginning of October, and move to the trunks of old pine trees, where they hibernate in bark crevices. The infestation level may be as high as 90% of the leaves on some trees.  相似文献   

Effect of some organic amendments on onion bulb rot     

N. Özer  N. D. Köycü  M. Mirik  H. Soran  D. Boyraz 《Phytoparasitica》2002,30(4):429-433

The effect of soil amended with stalks of sunflower (Helianthus annuus L.), alfalfa (Medicago sativa L.) and Hungarian vetch (Vicia pannonica Crantz) on onion bulb rot caused byFusarium oxysporum Schlecht. f.sp.cepae (Hanz.) Snyder Hansen andAspergillus niger v. Tieghem was tested in a soil naturally infested with the pathogens under field conditions. All treatments significantly reduced bulb rot incidence. The fungal and antibacterial populations varied among all of the amended tested soils. Heterotrophic fungal populations were more effective than heterotrophic bacterial populations in the suppression of disease. The highest population of fungal microflora was found in plots amended with sunflower stalks. The carbon-to-nitrogen ratio and available moisture content of amended soils have an indirect suppressive role on disease, by increasing the heterotrophic fungal population. http://www.phytoparasitica.org posting June 18, 2002.  相似文献   

Contribution to the knowledge of the families apionidae and nanophyidae (Coleoptera: Curculionoidea) from Turkey, with new records     

Rüstern Hayat  Şaban Güçlü  Hikmet Özbek  Karel Schön 《Phytoparasitica》2002,30(1):25-37

Data are presented on the occurrence of 43 species of the family Apionidae and two species of the family Nanophyidae in Turkey based on the material obtained mainly by beating stone-fruit trees in NE Turkey. The identity and information about the three species of Apionidae —Squamapion sp.cf.bifarium (Balfour-Browne),Protapion sp.cf.ruficrus (Germar),Catapion sp.cf.seniculus (Kirby) — must be revised. The faunistic data in the present paper on almost all species add to prior knowledge on their distribution in Turkey.Hypophyes aphyllae (Peyerímhoff),Ceratapion kasbekianum (Gerstaecker),Squamapion ottonis (Wagner),S. samarense (Faust),S. phocopus (Eppelsheim),Taeniapion rufulum (Wencker),Pseudoprotapion astragali (Paykull),P. ergenense (Becker),Stenopterapion intermedium (Eppelsheim) andOxystoma fausti (Desbrochers) are reported for the first time in the Turkish fauna. http://www.phytoparasitica.org posting Nov. 8, 2001.  相似文献
