The experiment was established in Wagner type pots with a capacity of 5 kg of soil in three replications. The substrate was a slightly acidic light loam with an average content of P, K, Mg and S and low Se content. Selenium was applied in the form of Na2SeO4 and Na2SeO3, and doses of: 0; 0.10; 0.25; 0.50; 0.75; 1.0; 2.0; 3.0 and 4.0 mg kg of soil. The ‘Lober’ strain of maize was used as a test plant and was cut down during the BBCH 73 phase. The conducted research demonstrated that the after entering into the soil 0.1 mgSe kg, form in which the element was used, did not affect the weight of the harvested crop corn. At all the rest selenium dosage levels the biomass cultivated in soil enriched with sodium selenate was higher than the biomass obtained after the application of sodium selenite. The application of selenium in the form of selenate (Na2SeO4) and selenite (Na2SeO3) caused a substantial increase in the content of this trace element in maize. The effect of the selenate was such that average Se content in plants was 13 times higher than the predetermined average for maize cultivated in soil with the selenite supplement. The introduction of selenium into the soil, especially in higher doses, triggered changes in the chemical composition of the maize. With the greater doses of Se(VI) the content of nitrogen, potassium and calcium content in plants decreased. The impact of that form of selenium upon phosphorus and sulphur content depended on the size of the applied doses. Selenium introduced in doses of 0.1–0.5 mg kg increased the content of P and limited the amount of S. At greater doses the reverse relationship was observed. Maize cultivated in soil enriched with Na2SeO3 contained less nitrogen and sulphur but more phosphorus, potassium, and calcium than that cultivated in soil with the selenate supplement.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68904158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since plant producers are not very experienced in the application of the morphoregulator to some varieties, the most widely grown oat varieties were used in the experiment. The field trial was established in 2009, 2010 and 2011 at the CVRV – VURV (Research Institute for Plant Production) Pieš any, the VŠS (Research Breeding Station) Víg3⁄4aš-Pstruša. The impact of the morphoregulator on reducing the stem and enhancing the number of productive tillers was confirmed in all the monitored varieties. Basing on the results of the trial, we do not recommend the application of CCC for ‘Auron’, ‘Atego’ and especially ‘Valentin’ varieties. For ‘Vendelin’ and ‘Zvolen’ varieties we recommend to consider the economic acceptability of morphoregulator applications. As economically acceptable we can recommend application of the morphoregulator only for the ‘Flamingstern’ variety.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68904817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the studies was the morphological analysis of the epicuticular waxes and the content of microelements in the needles of Scots pine growing in conditions of alkaline pressure, compared to the needles from emission-free areas. The studies were conducted on two-year-old needles collected in the vicinity of cement mills in Sitkowka and Ozarow, located in the Swietokrzyskie Province. The chemical composition analysis of needles indicated higher contents of Cu, Pb and Sr as well as lower content of Mn in the needles from alkalised areas. They were also characterised by higher contents of pHKCl than in the needles from emission-free areas. The images of needles, taken under a Scanning Electron Microscope (SEM), showed definite signs of epicuticular wax erosion in comparison to the needles collected from the control area. According to Turunen’s classification, third and fourth degrees of epicuticular wax coverage atrophy were found in two-year-old needles. The analysis of the chemical composition of the needles and the morphology of their surface structure indicated a negative impact of cement dust pollution on Scots pine’s assimilation apparatus.","PeriodicalId":44472,"journal":{"name":"ECOLOGICAL CHEMISTRY AND ENGINEERING A-CHEMIA I INZYNIERIA EKOLOGICZNA A","volume":"22 1","pages":"367-375"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68904461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
