### Radicle Length  
The length of pepper (_C. annuum_ L.) seedlings radicle (Table 11) completely corresponds with the results of the length of the hypocotyl length (Table 8). Nevertheless, it is visible from the results presented in Table 11 that only four comparisons between control and treated variants were significant. \begin{table}
