### Phytotoxicity of EOs in Liquid Phase
mugo_, which reduced it by up to 65%, 43% and 55%, respectively. The EO impact data on the germination of the receiver species were corroborated by the relative indices. At the four used concentrations, _A. alba_ decreased GI and CVG values of _L. multiform_ similarly (\(-\)28% to \(-\)84% and \(-\)27% to \(-\)85%, respectively), followed by _P. abies_ (\(-\)22% to \(-\)73% and \(-\)25% to \(-\)73%), _P. cembra_ (\(-\)53% to \(-\)71% and \(-\)55% to \(-\)71%) and _P. mugo_ (\(-\)19% to \(-\)52% and \(-\)21% to \(-\)57%). In the case of _S. alba_, only _P. cembra_ did not significantly change GIs and CVGs at 2 \(\mu\)L/mL. _P. abies_ reduced them by 47-74% and 27-79%, _P. mugo_ by 25-68% and 25-71%, _A. alba_ by 14-61% and 13-47%. On the other hand, _L. multiform_ and _S. alba_ MGT values increased up to a maximum of 16% and 21%, respectively, due to _A. alba_ and _P. abies_ EOs. The least effective EOs were those from _P. abies_
