Growth rates of diverse geographic strains of black alder in Maryland's tree nursery

Alnus lutinosa (123 different sources), A. cordata (4 sources) and A. incana 3 sources) were studied in Maryland's forest tree nursery. Average one-year height of A. glutinosa ranged from 9.7 cm to 40.1 cm, A. cordata from 16.8 cm to 32.0 cm, and A. incana from 26.2 cm to 30.5 cm. Black alder sources varied in color of summer foliage. All specimens were highly susceptible to the weed-controlling chemical "Paraquat." Additional keywords: provenance, genetics, diversity.
