Also discussed the results of our studies on marker enzymes in agamospermous (apomictic) progenies of sugar beet, pointing to the influence of chromosome polyteny on the epigenetic variability of enzyme genes and on the ratios of phenotypic classes of marker enzymes. Сomparison of the known with our experimental data enabled the consideration of differential polyteny of plant chromosomes, not only as a factor of epigenetic variability of gene expression, but also as a factor of evolution of the genome structural organization. Polyteny is considered to be an element of the system of recording hereditary information about epigenetic changes arising during ontogenesis.","PeriodicalId":30775,"journal":{"name":"European Agrophysical Journal","volume":"36 1","pages":"73-85"},"PeriodicalIF":0.0,"publicationDate":"2015-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85051021","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}

However, adoption of new farming systems on a regional scale is difficult unless an individual farmer is willing to take the personal risk and demonstrate the sustainability of the new system on a farm. The John T. Ingram and Sons Farm is an example that adopted a high residue conservation tillage system. Located on the Coastal Plains of Alabama, this farm has successfully operated as a high residue conservation tillage system since 1984 and served as an example for other farmers in the region. The following describes the system presently used on the John T.

Also, fuzzy indicator models are developed for cases where soil temperature in the root area are lowered so that damage to winter crops occurs.

To solve this problem, a tool for fuzzy multi attributive comparison of treatment alternatives was developed. The input data for the toll are technical and economic indicators, soil and agronomic characteristics, as well as expert opinions. The output from the tool is a ranking of the treatment alternatives. Application of the tool can significantly reduce the time to carry out the multi-attributed comparison of alternatives, making it possible to unify the process of comparing them, providing an assessment of alternatives that is less dependent on the preferences of the scientist, and creates the conditions for more informed management decisions. In this article, a tool for fuzzy multi attributive comparison of alternatives was applied for evaluation of long-term impacts of tillage and cropping systems. Yield data (1981-2001), which were used in this study, showed that the various combinations had pros and cons over time. The results from the utilization of the tool indicated that the combination of chisel tillage with a cover crop rotation was the best alternative. In addition, it was determined that where poultry litter was added to the wheat cover crop (or harvested for grain), the combination of conventional tillage with a cover crop rotation was the best alternative. Results of the computer simulation using the tool for fuzzy multi attributive comparison of alternatives provided a procedure to summarize long-term experimental data.","PeriodicalId":30775,"journal":{"name":"European Agrophysical Journal","volume":"14 1","pages":"85-105"},"PeriodicalIF":0.0,"publicationDate":"2014-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81746595","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}
