Исследования проводились в почвенно-климатических условиях центра Среднерусской возвышенности (Орловская область). Серая лесная среднесуглинистая почва опытного участка имела высокий уровень обеспеченности обменными соединениями кальция 14,8 ± 0,5 ммоль/100 г. Пять раз за период вегетации проводились раздельные и совместные некорневые подкормки деревьев Н3ВО3 (0,1 %), К2SО4 (0,3 %) и СаСl2 (1 %). Результаты исследований показали, что метеоусловия и нагрузка урожаем были главными факторами, влияющими на концентрацию кальция в листьях, кожице и мякоти плодов обоих сортов. Независимо от наличия кальция в составе удобрений листовые подкормки в большей степени изменяли содержание кальция в тканях плодов, чем в листьях. Все обработки так или иначе приводили к изменениям концентрации кальция в тканях плодов, но в разные годы в одних и тех же вариантах наблюдался противоположный эффект. Сорт Синап Орловский (известный своей восприимчивостью к горькой ямчатости) проявил большую отзывчивость на некорневые обработки, чем сорт Имрус. В2013 г. плоды обоих сортов отличались наименьшей концентрацией кальция (3,87±0,25 мг/100 г сырой массы), что было в два раза ниже, чем в предшествующие и последующие периоды вегетации. В этот год не наблюдалось существенного роста концентрации кальция в плодах после некорневых подкормок, а некоторые обработки приводили к значимому снижению показателя. Несмотря на высокий уровень обменного кальция в почве, концентрация кальция в листьях была низкой для обоих сортов: Синап Орловский 0,75±0,08 %; Имрус 1,08±0,14 % сухой массы. Для обоих изу-чаемых сортов была установлена значимая отрицательная корреляция между содержанием элемента в листьях и тканях плодов (R= -0,46…-0,34; P&lt;0,05).</p></abstract><trans-abstract xml:lang="en"><p>The influence of foliar fertilization on calcium concentrations in leaves and apple fruit tissues ( flesh and skin) has been studied in the field experiment with mature ‘Imrus’ and ‘Sinap Orlovsky’ apple trees varieties in 2011-2015 growing seasons. The experiment was conducted in pedoclimatic conditions of forest-steppe of the Central Russian Upland (Orelregion). The experimental orchard is on loamy grey forest soil with high calcium content 4,8 ± 0,5 mmol/100g. The separate and combined foliar nutrient treatments with Н3ВО3 (0,1 %), К2SО4 (0,3 %) and СаСl2 (1 %) were applied five times during the vegetation period. The results showed that meteorological conditions and yield load were the main factors aﬀecting on calcium concentrations in leaves and fruit flesh and skin of both varieties. Foliar fertilization regardless of the calcium presence in the composition of fertilizers to a greater extent changed the calcium content in apple fruit tissues, then in leaves. All treatments one way or another resulted in changing of calcium concentration in fruit tissues, but in diﬀerent years the contrary eﬀect of the same treatments was observed. The variety ‘Sinap Orlovsky’ (known for its high susceptibility to bitter pit) was more responsive to foliar treatments, than the variety ‘Imrus’. In 2013 fruits of both varieties were remarkable for the least calcium concentrations (3,87±0,25 mg/100 g of fresh wt), and it was two times smaller than in the previous and following growing seasons. In the same year essential increase of calcium concentration in fruits was not observed after foliar fertilization, but some treatments resulted in essential reduce of this index. Despite of high soil calcium content calcium concentrations in leaves were low for both varieties: ‘Sinap Orlovsky’ – 0,75±0,08 %; ‘Imrus’ 1,08±0,14% dry wt. Signi fi cant negative correlations (R= -0,46…-0,34; P&lt;0,05) were measured between calcium contents in leaves and fruit tissues of both varieties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>яблоня</kwd><kwd>минеральное питание</kwd><kwd>некорневые подкормки</kwd><kwd>кальций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Malus domestica</kwd><kwd>mineral nutrition</kwd><kwd>foliar fertilization</kwd><kwd>calcium</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Трунов Ю.
