Описание:
In the second year of commercial fruiting the nitrate content in berries of low bush blueberry was 13.5 mg/kg. As compared to 2011 (the first commercial harvest) it number decreased in 4.3 times. In the conditions of the same amount of applied mineral fertilizers the different content of nitrate in berries of two harvest years can be explain by change in regulations of feeding, manifestation of effect of “dilution” of nitrates in actively being formed with age biomass of cultivated plants and features of weather conditions. In 2012 crop year, the content of nitrate did not depend on the time of harvest, the average weight of fruit and plant genotypes. Storage of berries of a crop of 2011 within 12 months in a freezer at a temperature of minus 16 (+ / –2) °C resulted in a decrease in nitrate concentrations in 2.8 times of their initial quantity.
