Аннотация

Paulownia sp. are tall and fast-growing perennial plants that grow faster than all woody plants in the
world. In many countries, Paulownia sp. are used as a raw material in bioenergy, furniture industry, landscape
gardening and technologies for phytoremediation. In this study for the first time in Kazakhstan, conditions of
Paulownia tomentosa (P. tomentosa) in vitro cultivation and propagation have been optimized, also the factors
influencing the morphogenetic activity of primary explants have been studied. Along with the adaptation potential of
Paulownia tomentosa microclones to the ex situ conditions, laboratory standing order for microclonal reproduction
have been evaluated.
For sterilization of P. tomentosa explants are recommended to use 50% domestos and 0.1% merthiolate.
Hormone-free WPM medium was considered as the most optimal for the in vitro propagation. Infrared light is highly
recommended for P. tomentosa microclones adaptation, due to its ability to stimulate the formation plants
aboveground biomass and root system.
For Kazakhstan, the research of this type of tree crops is a relevant, new and promising direction. The
development of microclonal propagation of Paulownia tomentosa will accelerate the process of introduction of
Paulownia in our Republic.
