The aim of this thesis was comparing growing of beech plants in different conditions under preparatory stands of alder and birch on LS LČR Šternberk district. There were 15 sites (8 under alder stand and 7 under birch stand) on which were made in different ways mining interventions in preparatory stands. There were measured overall 7 parametres (total height of seedlings, seedling height of last year, increment per the last year, length and width of the leaf, root collar diameter and deflection of stem from the vertical axis). Based on weight rating was find out, that each one of preparing stands has different impact to underplanted cultures. Under birch preparing stand was best conditions find out at site, where was density of stand reduced to 30 %. Under alder preparing stand was the best conditions find out under preparing stand with full density. The worst conditions for underplanted cultures were find out at sites without preparing stand (at clearcuts).
