“…Cold strati cation has also been demonstrated to serve a substantial in uence in reducing the higher temperature requirements for seed germination by some Tundra species (Baskin and Baskin 2001). In various studies, Rhododendrons showed enhanced germination after cold strati cation, such as in Rhododendron arboreum Smith, where germination increased signi cantly on strati cation but declined as the strati cation period progressed (Vipasha et al 2017), and Rhododendron aureum, where germination percentage was also higher in moist chilled treated seeds (Shimono and Kudo 2005). The cold strati cation requirement in nature in alpine areas is ful lled by their snow fed beds, but due to the current climate change scenario, increasing soil temperature leads to earlier snow layer thinning, so the stratifying requirement of the seeds may not be completed, resulting in low propagation via seeds in some alpine ora in the near future (Briceño et al 2015).…”

Rhododendrons are the Himalayan ecological, cultural, aesthetic, and economic entity; some of its varieties are edible and medicinal. Rhododendron anthopogon D. Don is an alpine Rhododendron that grows above tree lines in the Himalaya. This is a dwarf Rhododendron with fragrant leaves that are employed in numerous traditional Himalayan medical systems. This plant's essential oil is pale and contains antibacterial, antioxidant, and insecticidal effects. This manuscript comprises an eco-physiological investigation of R. anthopogon on an altitudinal and seasonal basis in the Tungnath Himalaya of Uttarakhand, India. We observed that the altitudinal gradient shapes the phyto-sociology of R. anthopogon, which is one of the dominant species in its habitat. Leaf morphology and phytochemicals (pigments, total soluble sugar, starch and protein, total phenolic content, Malondialdehyde content, Superoxide dismutase and Peroxidase enzyme activities) of the R. anthopogon leaves showed altitudinal and seasonal variations, indicating their importance in thriving in the harsh alpine conditions. The seed germination experiment in R. anthopogon was also carried and observed that the synergistic effect of cold stratification and GA3 reduced the mean germination time while increasing the final germination percentage.
