Аннотация

The effect of cinnamyl alcohol (CA) on the biosynthesis of rosavins was examined in Rhodiola rosea L. plants during in vitro or ex vitro culture. An additional factor‒a source of carbohydrates‒was introduced into the in vitro culture experiments. The study revealed a high concentration of rosin in the in vitro culture during treatment with CA (67–98% of total rosavins). It was shown that glucose does not have a stimulatory effect on the production of rosavins in the in vitro culture but changes its ratio. In the ex vitro culture, an increase in the amount of total rosavins after the introduction of CA was caused by enhanced biosynthesis of rosavin and rosarin, whereas the level of rosin did not differ from a control. Additionally, a stimulatory effect of CA on the growth of root biomass and of the above-ground part of the plants was noted under ex vitro conditions. Thus, we demonstrated that the levels and ratio of rosavins differ significantly between the CA group and control group during in vitro and ex vitro culture. In vitro culture of regenerated R. rosea plants after treatment with CA can serve as a source of rosin (0.56%).
