Abstract
The objective of this work was to determine the effectiveness of auxin growth regulators for processing of green cuttings of highbush blueberry before planting them for rooting. Experiments were conducted in 2016-2017, in the Research and Production Nursery peasant-farmers hold “Cherry garden”, village Besovo, Kaluga region. The experiments were performed on highbush blueberry Bluecrop and Northland varieties. Before the rooting of green cuttings treatments with synthetic auxin growth regulators in the form of water, alcohol solutions and growth powder were performed. Alcohol solution of indole-3-butyric acid (IBA) (5 g/l) or growth powder Ukorzeniacz (0.2 %) were shown to be the most effective stimulators of rooting in green cuttings “with heel”. Not treated with any growth regulators plants were used as a control. Rooting rates of green cuttings of Bluecrop blueberry variety were 73-78 % in comparison to 49 % of the control, whereas Northland blueberry variety showed 74- 77 % rooting rates in comparison to 60 % in the control.
