### Changes in the Early Growth of Red Clover Seedlings  
The length and weight of germinated seedlings was measured 7 days after sowing in order to estimate whether the effects of CP and EMF treatments on early seedling growth are dependent on seed color (Figure 3).

The results showed that the effects of treatments on the early growth of red clover 'Arimaiciai' seedlings depended on seed color. Positive effects on germination (Table 1) were followed by improved growth parameters (Figure 3). The length of seedlings germinated from yellow seeds was larger in CP5-, CP7-, EMF10-, and EMF15-treated groups, compared to the control (by 31, 18, 22, and 20%, respectively), but the weight of seedlings increased by 15% only in EML10 group (Figure 3). An increase in length (but not weight) of seedlings from dark purple seeds by 37 and 13% was observed in CP5 and CP7 groups, respectively. In contrast, treatments did not change the seedling length from brown seeds, although seedlings in C5 and C7 groups were 21 and 26% heavier compared to the control.
