Resting, vegetative buds collected from 26- to 120-year-old trees of Picea abies (L.) Karst. were tested for the capacity of forming adventitious buds in vitro. The buds were collected from trees grown in the field and from rooted cuttings or grafts from the same trees, cultured in a phytotron. In the phytotron, plants produced from rooted cuttings were used as a source of new cuttings from which more plants were regenerated. Marked differences in the ability to form adventitious buds were observed among various clones. For most clones the bud-producing capability increased after preculturing of the plant material in the phytotron. The capability of each done to form adventitious buds was correlated to growth rate in the field and to the rooting frequency of cuttings. Forest Sci. 30:314-318.
