Abstract
Shoot cuttings of Actinidia arguta from opposite parts of shoots were prepared and treated
with different types of commercially produced growth stimulators. Tests were conducted with
shoots in three different vegetation stages during the year. The number of adventitious roots
and the length of the longest root were recorded. Results were statistically analysed in the Randomised
Block Design for factorial experiments. Selected growth stimulators and different parts of shoots
proved to have statistically singnificant influence on root initiation and their length in all three
phenological phases. However, their interactions were non-significant, which proved their relative independence.
The combination of Gelstim B stimulator and apical cuttings appeared to be the most effective in case of cuttings
collected in the end of February and in the first third of November. For best rooting of semi-woody cuttings
collected in the first third of June, the most effective significant combination appeared to be Gelstim B and basal
parts of shoots.
