Abstract:
The data on the rooting ability and peculiarities of root system formation of hard-wood and soft-wood cuttings of Ribes atropurpureum under the action of growth regulators are presented. The positive influence of humat potassium, tellura-M, and phoenix in the concentration of 0.5–1% on branching and root length of different orders of ramification in hard-wood and soft-wood cuttings was established. Hard-wood cuttings formed longer roots of orders I and II of ramification, but branching was poorer than that in soft-wood cuttings.
