Study on excised root respiration and its application to in situ measurement of root respiration;

Effects of water deficit on the rate of leaf photosynthesis and root respiration in two winter wheat of different drought resistance;

The dynamic response of plant root respiration to increasing temperature and global warming;

Information on root respiration and biomass are important for understanding implications of environmental change on soil carbon cycling and sequestration.

Daily and seasonal variation of soil CO2 emission fluxes were measured using close chamber method in typical crop fields in Huang-huai-hai Plain, the impacts of soil temperature and moisture on soil CO2 emission flux were analyzed respectively, and the contribution of root respiration by using the DNDC ( DeNitrification – DeComposition ) model was also discussed.

In order to determine the possibility of measuring the root respiration by using root exclusion method,we conducted field experiments to measured total soil respiration and net soil respiration in three temperate grassland communities including Leymus chinensis free-grazed steppe,stipa grandis free-grazed steppe and Leymus chinensis degenerated free-grazed steppe in the growing season, 2005.

Effect of elevated atmospheric pCO_2 on rhizospheric respiration during the wheat growth period from 106-183 days after germination;

The IRGA(infrared gas analyzer) research methods were carried out to measure soil respiration and fine root respiration in three different complex ecosystems ((Betula luminifera+ Hemarthria compressa, Betula luminifer + Pleioblastus amarus, Betula luminifer) in converting farmlands to forest in Sichuan basin in Hong-Ya county (29°24′N, 102°49′E) in this article.
