ASSESSMENT OF COLLECTION NURSERY OF LEEK (ALLIUM PORRUM L.) FOR SELECTION ON STEADILY LOW LEVEL OF ACCUMULATION OF RADIONUCLIDES

Abstract

Studies were conducted in the Moscow region. The object of research is leek (Allium porrum L.). As a result of carrying out an experiment with ten grades of leek of domestic and foreign selection high-quality reaction on accumulation of radionuclides 137Cs and 90Sr is revealed. It is found out that leek is not the fissile accumulator of accumulation of pollyutant in the conditions of the Central Non-black zone. On the average on ten varieties accumulation 137Cs 13.5 made Bq/kg, at a grade 4. However at the study of high quality standards forms that contained less radionuclides in comparison with others were allocated. On maintenance 90Sr distribution on the groups of accumulation of sorts approaches normal. A group is most representative with the middle level of accumulation of radionuclide 90Sr: from 15.4 to 16.5 Bq/kg. It contains two standards from ten studied forms by the high level of maintenance 90Sr sorts differ Goliath and Kazimir. In the conditions of vegetation of 2016 and 2017 indicators on morphological features are received: number of leaves, plant height, leaves length, leaves width. By us it is defined that the varieties of Giraffes, accumulating 137Cs in less as compared to other standards of varieties, excels substantially all standards of varieties 137Cs on such quantitative sign as a "number of leaves". It should be noted that the analysis of the received results demonstrates that at a high level of accumulation 137Cs of a plant created larger leaves and had higher chance stalk in comparison with plants with low level of accumulation of an element (137Cs).
