“…Over the past few years, the cultivation of plants has been facing a number of challenges, including a dramatic increase in temperatures, lack of soil water, and the need for more resistant and hardy plants, which grow even under the harshest conditions. It is therefore vital to minimise the time required for the growth of planting material, which can be done using growth and germination stimulants, including synthesised chemical compounds Pentelkina, 2003;Vasin et al, 2008Vasin et al, , 2009Ostroshenko and Ostroshenko, 2011;Schuchka, 2006;Baranova, 2013a;Khodaei-Joghan et al, 2018;Nesterkina et al, 2019) and other original modes (Shibaeva et al, 2018).…”

Synthesised organic compounds of pyrimidinecarboxylic acids are characterised by high biological activity, even when their concentrations are low. These compounds, when applied to the seeds of Rhododendron, a genus of woody plants, with concentrations of 0.01, 0.05, and 0.1 %, stimulate the growth of the plants. The effect is more obvious 3 months after the start of the experiment, rather than 7 months after. Thus, Rhododendron ledebourii Pojark. seedlings grew by 13.3-33.5 %, and Rhododendron smirnowii Trautv. seedlings grew by 29.6-48.1 %. Rhododendron ledebourii and Rhododendron smirnowii seedlings demonstrated similar direct correlations: when the concentration of 2-benzylamino-4-methyl-pyrimidine-5-carboxylic acid and 4-methyl-2-morpholin-4-pyrimidine-5-carboxylic acid (for Rhododendron ledebourii seeds only) rose from 0.01 to 0.1 %, the height of the seedlings increased. It is suggested using 4-methyl-2-piperidin-1-yl-pyrimidine-5-carboxylic acid, 2-benzylamino-4-methyl-pyrimidine-5-carboxylic acid, and 4-methyl-2-morpholin-4-pyrimidine-5-carboxylic acid at concentrations of 0.01, 0.05, and 0.1 % as growth stimulants for the species of Rhododendron genus.
