Abstract
Saditev je v gozdarski praksi uveljavljen in najbolj pogost način pomlajevanja doba. Tetave pri tem so visoki stroški saditve, veliko potrebne nege in pogosto veliki izpadi ter slaba kakovost. V nalogi je bila analizirana uspešnost saditve v 12 in 11-letnih letvenjakih, ter primerjana z enako starima naravnima letvenjakoma. Rezultati so pokazali, da se višina izpadov ne razlikuje glede na različna leta saditve. Razlike v izpadih so pogojevale različne razmere na rastiščih. Najbolj negativno je na uspešnost saditve delovalo intenzivno širjenje in razraščanje robinije ter hitro odpiranje sestoja z golosekom. Slednje je povzročilo zamočvirjenje in agresivno rast pritalne vegetacije, izpadi sadik, sajenih v letih 1998 in 1999 so na tem rastišču znašali 78 % in 83 %. Naravno pomlajevanje se je izkazalo za uspešnejše kot saditev. Višja je bila gostota dreves (9 550 dreves/ha), z visokim deletem doba (80 %), in boljša je bila tudi kakovost - povprečna doltina čistega debla je znašala 4,4 m. Na podlagi rezultatov naloge in navedene literature je bilo priporočeno, da se tudi pri nas preizkusijo novi načini saditve na delnih površinah. Stroški pri teh konceptih so nižji, uspeh pa obetaven. Na občutljivih dobovih rastiščih bi bilo bolje pomlajevati s postopnim odpiranjem sestoja, z zastornimi sečnjami, kot z golosekom.

Abstract:
Planting is the most established and common way of regeneration of oak stands in forestry practices. Problems with planting are high costs, a lot of tendingis needed, high losses are frequent and the final quality may be poor. In this project efficiency of planting in 12 and 11-year-old pole stands have been analysed. Those have been compared with the same age pole stands, which were regenerated naturally. According to the results, the losses did not depend on different year of planting, but they were more likely caused by the site and its specific conditions. Expansion and proliferation of false acacia and clearcuts affected plantation success negatively. Clearcutting caused swamping and overgrowing of the site with weed. Losses of plants from 1998 and 1999 amounted 78 % and 83 %, respectively. Natural regeneration was more successful than planting. Tree density was higher (9 550 trees/ha), with high share of pedunculate oak (75 %) and the quality was better - average hight of branch-clear stem was 4.4 m. Suggestion about the future forestry practice in Slovenia is to introduce new approaches of planting in Slovenia, e.g. partial-surface (cluster) planting. This concept offers costs reduction and a better success. On vulnerable pedunculate oak forest sites it would be better to cut trees progressively than using clearcutting.
