ABIES alba ... RHODODENDRON ferrugineum. Eleven flavonoids were isolated and characterized, with quercetin 3-O-[6″-O-(2-methyl-1-oxobutyl)]-β-D-glucopyranoside and 2R,3R-dihydromyricetin 3-O-β-L-arabinopyranoside as new natural products. Ice propagation was studied in various alpine plant species: an herb (Senecio incanus L.), a woody shrub (Rhododendron ferrugineum L.), two graminoids (Poa alpina L. and Juncus trifidus L.), and a cushion plant (Silene acaulis [L.] Jacq.). 32 No. 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).

Measurements of transpiration and photosynthesis (gas exchange) at wind speeds of 0.5-8.0 m./sec. In the European Alps, Rhododendron ferrugineum can constitute dense populations with almost 100% of cover. Summary. duction in R. ferrugineum populations (2) when and how layers develop in these populations, and (3) wheth er reproductive traits and reproductive strategies devel op relative to the degree of population closure and maturity. Rhododendron (from the Greek: rhodos, "rose", and dendron, "tree") is a genus of flowering plants in the family Ericaceae.It is a large genus with over 1000 species and most have showy flower displays. Tree species dominate many ecosystems throughout the world and their response to climate, in light of global warming, is a matter of primary concern.
