Sumario:[EN] Shoot cultures from adult material of common alder (Alnus glutinosa) were established in vitro. Branches from the canopy and stump sprouts were collected from 20-30-year-old trees. Shoots developed from these branches were used to initiate the cultures using Woody Plant Medium supplemented with 2 mg/l benzyadenine and 0.5 mg/l indole acetic acid. The multiplication stage was divided into 3 cycles of 3 weeks each, transferring the shoots to fresh medium at the end of each cycle. Woody Plant Medium was used in this stage supplemented with 0.5 mg/l indole acetic acid, 0.2 mg/l benzyladenine (during the first cycle, 0.1 mg/l for the next two), and 0.5 mg/l zeatin in the 3rd cycle. Shoots (1.5-2 cm) from the multiplication stage were rooted in vitro. Rooting percentages getting up to 75% both in controls and with 0.1 mg/l indole butyric acid, although the presence of auxin increased the speed of root formation.
