Seed germination after freezing in high-mountain plant species: Implications for ski-run restoration Phyton
Díaz-Miguel,M; Castro,J; García,PA.
The construction of a ski slope implies a strong environmental impact as a result of the removal of the vegetation cover. The need to protect the soil requires a rapid restoration of vegetation, which is often done with commercial seed mixtures that can cause a negative impact on these high mountain ecosystems. Thus, the use of seeds of native species is essential, especially in areas rich in endemic species. The compaction of snow as a result of the preparation of the ski slopes causes the soil to freeze. This hinders the germination of seeds, especially those of shrub species. This paper analyzes, under laboratory conditions, how freezing and phytohormone application affect the seed germination of three endemic shrubby species used in the restoration of...
