Abstract
Purpose of the work is to identify peculiarities of intraspecific polymorphism of Thuja occidentalis L. on the basis of literature data as well as to improve the method of decorative forms reproduction by cuttings which includes selection of optimal timing for slicing the cuttings and cutting process; determining the effect of the most common commercial rooting stimulants for root formation in the cuttings of Thuja occidentalis L. |The paper describes briefly biological characteristics of Thuja occidentalis L and presents the ways of its use in landscape gardening art. The relevance of the studies is formulated. In addition, a brief description of the most common decorative forms in horticulture is done. Characteristic of an experimental research on vegetative propagation by cuttings using a variety of stimulants rooting is given for the following decorative forms of the investigated species: 'Aurea', 'Smaragd', 'Bodmeri', 'Danica nana' and 'Elegantissima'. The results obtained show that for the propagation of decorative forms of the Thuja occidentalis L. by cuttings the best to use are winter cuttings which are treated with stimulant "Нeteroauxin Super" providing 86–92 % of rooting for corresponding decorative forms. During reproduction by green cuttings, somewhat lower results were obtained in all variants of the experiment. The best of considered stimulants is "Kornevin", usage of which resulted in rooting of 66 to 82 % of cuttings.
