Studies on triploid clones of silver wattle (Acacia dealbata) in southeast Tasmania

摘要

Silver wattle (Acacia dealbata) is common in forests and woodlands in Tasmania at elevations up to 900 m, and is often the dominant tree species in transitional forests establishing on disturbed sites (Kitchener and Harris 2013). The species varies in size from a low shrub on dry, shallow soils to a tall straight tree over 25 m in height on deep soils on wetter sites (Boland et al. 2006). Since being introduced to many countries outside Australia, it has been widely planted for ornamental purposes and perfumery (Griffin et al. 2011).
