Consumption structure of mineral components of nutrient solution by black currant regenerant plants under in vitro cultivating
Abstract
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.
