Summary
Seeds were collected from shrubs and brushwood of Lonicera involucrata (Rich.) Banks ex K. Spreng. in coastal Oregon (44–45° N) and interior British Columbia (54–55° N). The annual shoot growth of the resulting half-sib families and populations was studied in Ås, Norway (60° N). The move of these locally adapted types to a new environment revealed the great genetic variation within and between provenances. The start and duration of the growing period were mainly determined by latitude, while the growth rate varied more between provenances than within. Different statistical approaches are discussed.
