### Changes Induced in Growth Dynamics in the Field  
The morphometric analysis of seedling growth in the field was performed 4, 8 and 14 weeks after sowing; the latter time point coincided with buckwheat harvesting. The obtained results are presented in Figures 1-3 respectively. Morphometric parameters of shoot and root growth in the control groups of two buckwheat cultivars were similar 4 weeks after sowing (Figure 1a,b). However, the number of lateral branches in 'VB Nojai' seedlings was 84% higher, and the number of infloresences was 5.8 times larger compared to 'VB Vokai', indicating that 'VB Nojai' started branching and flowering earlier (significance of differences between the control groups of two cultivars was estimated by Student's test, \(p\leq\) 0.05). 'VB Vokai' seedlings in the CP7 group differed from other groups by the fastest growth of the above \begin{table}

Table 1: Indices of buckwheat germination kinetics in vitro. ground part and root: seedling height was increased by 7%, weight 41%, root weight 36%, and plants developed 2 times more lateral branches, 24% more leaves, which weighed 41% more compared to the control. Certain morphometric indices such as seedling weight, number and weight of the leaves were also better in plants of the CP5 group compared to the controls. The most notable difference was 3.6 times higher number of infloresances. Seed treatment with EMF15 had no effect on the morphometric parameters of 'VB Vokai' 4 weeks after sowing, but EMF10 increased the seedling weight (by 20%) and the number of lateral branches (2.1-fold).
