The stimulating effect of lanthanides on the accumulation of rubber in the roots of dandelion Taraxacum hybernum (Krym-saghyz) was demonstrated along with its environmental consequences. The treatment of Krym-saghyz plants with nitrates of lanthanides led to the increase of poly (cis-1.4-isoprene) concentration by 80% compared to the untreated plants and by 45% compared to those treated with magnesium nitrate. The observed increase of rubber concentration in Krym-saghyz plants has been assumed to be related to the activation of photosynthesis (up to 40%) and the inclusion in the reactions of rubber synthesis of isopentenyl pyrophosphate (IPP) formed from methylerythritol phosphate (MEP) in green plastids.
