A comparative researches on seed germination of 15 plant species from alpine meadow
|
Abstract:
Germination test of 15 alpine plant species showed that stratification, temperature fluctuation and light conditions could improve or decrease germination percentage of the most of alpine meadow plant species. In which, 13 plant species responded to stratification significantly, 11 species responded to light conditions, and 14 plant species responded to temperature fluctuations. Of all the 15 plant species, single factor or combinations of factors had significant effects on germination of 14 plant species. Aster flaccidus is the only species that did not response to any factor or combination of factors. Herein seeds of alpine plant species could be categorized to different response types according to their germination performance under different conditions. Study is essential to understand the germination behavior of plant species under specific conditions for the restoration of degraded alpine meadow communities from seed regeneration.
