Abstract
The best time for a propagation of Myricaria bracteata and M. longifolia hardwood cuttings in Novosibirsk is the first decade of May. Cuttings that are planted in expanded clay and sand root well. A small concentration of growth stimulator IBA (Indole-3-butyric acid) doesn’t have an evident impact on the number of rooted cuttings. However, it contributes to development of a more powerful root system. High concentrations of IBA inhibit the process of root formation and at increased concentrations a basal part of a cutting dies off. Use of IBA water solution turn out to be more effi cient than after treatment with alcoholic solution or powder.
