For the first time to our knowledge, we report here methane emissions by plant communities in alpine ecosystems in the Qinghai-Tibet Plateau. This has been achieved through long-term field observations from June 2003 to July 2006 using a closed chamber technique. Strong methane emission at the rate of 26.2+/-1.2 and 7.8+/-1.1microg CH4 m-2h-1 was observed for a grass community in a Kobresia hum...
High temperature is an important environmental factor that affects plant growth and crop yield. Potentilla fruticosa L. has a developed root system and characteristics of resistance to several stresses (e.g., high temperature, cold, drought) that are shared by native shrubs in the north and west of China. To investigate thermotolerance mechanisms in P. fruticosa, 3-year-old plants were subjecte...
BACKGROUND AND AIMS High alpine environments are characterized by short growing seasons, stochastic climatic conditions and fluctuating pollinator visits. These conditions are rather unfavourable for sexual reproduction of flowering plants. Apomixis, asexual reproduction via seed, provides reproductive assurance without the need of pollinators and potentially accelerates seed development. There...
The present article describes the heavy metal content (Ni, Pb, Cd) in top plant phytomass: blue marsh bog (Eleocharis palustris (L.) Roem. Schult.), furcular Anemonidium (Anemonidium dichotomum Holub), bayonet rush (Juncus filiformis L.), vetchling (Lathyrus carex acuta (Carex reed canary grass (Phalaroides arundinacea clump speedwell (Veronica longifolia silverweed cinquefoil (Potentilla anser...
