Установлено потребление минеральных компонентов питательных сред растениями-регенерантами смородины чёрной в культуре in vitro. На этапе микроразмножения отмечено существенное снижение концентрации большинства ионов в питательной среде: максимальное для NH4+ (80,11–87,17 % от исходного количества в среде), на ⅓ часть уменьшается количество K+ и Mg2+. Несколько меньше потребляется микрорастениями Ca2+ (15,62 %–21,09 %). Отмечена разница и в поглощении анионов из питательной среды. Максимально использовались ионы H2PO4- (58,48–62,28 %) и NO3- (56,75 %–62,02 %) и на ⅓ ионы Cl- и SO42-. На этапе укоренения растения-регенеранты смородины чёрной максимально поглощают из питательной среды H2PO4- (в среднем 88,5 %). Хорошо усваивается азот, как в нитратной (до 64,37 %), так и в аммонийной форме (до 76,88 %). Поглощение иона SO42- составляет более ½ от исходного количества в среде. На этапе ризогенеза уменьшается относительное потребление аммонийного азота, калия и хлора, в то же время увеличивается – магния, кальция, серы и фосфора, по сравнению с этапом микроразмножения.

Consumption of mineral components of nutrient solutions by black currant regenerant plants in in-vitro culture was established. At a microreproduction stage essential decrease in concentration of the majority of ions in nutrient solution was noted: maximum for NH4 + (80.11-87.17 % from initial quantity in the solution), quantity K+ and Mg2+ decreases by ⅓ part. A little bit less is consumed by microplants Ca2+ (15.62 %-21.09 %). The difference in anion absorption from a nutrient solution is also noted. Ions H2PO4 - (58.48-62.28 %) and NO3- (56.75 %-62.2 %) and by ⅓ Cl - and SO4 2-ones were used to the maximum extent possible. Black currant regenerant plants maximum absorb H2PO4 - (on the average 88.5 %) from a nutrient solution at the rooting stage. Nitrogen takes up well both in nitrate (up to 64,37 %) and ammonium (up to 76,88 %) forms. Ion SO4 2- absorption makes more than l/2 from initial quantity in the solution. At a rhisogenes stage relative consumption of ammonium nitrogen, potassium and chlorine decreases. At the same time magnesium, calcium, sulphur and phosphorus consumption increases in comparison with a microreproduction stage.
