rhododendron ferrugineum propagation

Seed Catalog . The first reliable information on the occurrence of Rhododendron ferrugineum in the Karkonosze Mts (excluding spots of directly acknowledged anthropogenic origin) was provided by A. Boratyński in 1983, but the status and origin of the plants were unknown. Initial results for Rhododendron ferrugineum, obtained by infrared differential thermal analysis (IDTA; Hacker and Neuner, 2007, 2008; Hacker et al., 2008), indicated that ice can propagate nearly unhindered into flowers during anthesis but not into individual florets of winter buds (Neuner and Hacker, 2012). The tropical rhododendrons (sect. for Rhododendron ferrugineum, Vaccinium myrtillus, Vaccinium vitis … Rhododendron ferrugineum seems to fit well with the usual theories concerning plants that grow in drastic environments: (1) this species spreads vegetatively and (2) has a high sexual reproduction potential (0.4–2.5 million seeds/m 2 of heathland; Pornon et al., 1997).
