The stimulating effect of ytterbium nitrate on seed germination, photosynthesis, and accumulation of carbohydrates in the roots of the krim-saghuz dandelion (Taraxacum hybernum) was demonstrated. Differences between lanthanum and ytterbium in their effect on the efficiency of PS II (Y(II)). At a concentration of 100 μmol, lanthanum reduced Y(II) due to an increase in the contribution of the quantum yield of controlled dissipation of a part of the energy (Y(NPQ)), and ytterbium reduced it due to the contribution of irreversible dissipation of energy (Y(NO)). When the concentration of lanthanides was reduced by ten times, the stimulating effect of Y(II) was observed only for ytterbium. In field experiments, plants treated with 10 μmol ytterbium nitrate solution had a 31% higher rate of photosynthesis, which probably influenced the accumulation of rubber and carbohydrates in dandelion roots, which was 13 and 26% higher, respectively, than the untreated plants.
