“…Similar to seeds, buds of perennial species establish dormancy, partially desiccate to tolerate frost, and accumulate LDs. Indeed, the presence of LDs in buds has been reported in several perennial species such as birch (Rinne et al, 1999;Rinne et al, 2001), Norway spruce (Guzicka and Wozny, 2003;Guzicka et al, 2018), aspen and poplar (Sagisaka, 1992;Rinne et al, 2011;Veerabagu et al, 2020;Veerabagu et al, 2021), willow (Berggren, 1984), pine (Jordy, 2004) and Cunninghamia lanceolate . LD abundancy is described to vary during winter dormancy progression (Rinne et al, 2001;Sutinen et al, 2009;Sutinen et al, 2012).…”
