Effects of Elevated Carbon Dioxide, Elevated Temperature, and Rice Growth Stage on the Community Structure of Rice Root–Associated Bacteria
The effects of free-air carbon dioxide enrichment (FACE) and elevated soil and water temperature (warming) on the rice root-associated bacterial community were evaluated by clone library analysis of the 16S ribosomal RNA gene. Roots were sampled at the panicle initiation and ripening stages 41 and 92 days after transplanting (DAT), respectively. The relative abundances of the methanotrophs Meth...
متن کاملEffect of elevated CO2 and high temperature on seed-set and grain quality of rice
Hybrid vigour may help overcome the negative effects of climate change in rice. A popular rice hybrid (IR75217H), a heat-tolerant check (N22), and a mega-variety (IR64) were tested for tolerance of seed-set and grain quality to high-temperature stress at anthesis at ambient and elevated [CO(2)]. Under an ambient air temperature of 29 °C (tissue temperature 28.3 °C), elevated [CO(2)] increased v...
متن کاملEffect of CO2 enrichment and elevated temperature on methane emissions from rice, Oryza sativa
Methane emissions from rice grown within Temperature Gradient Greenhouse Tunnels under doubled CO2 concentrations were 10±45 times less than emissions from control plants grown under ambient CO2. For two cultivars of rice (cvs. Lemont and IR-72), methane emissions increased with a temperature increase of 2°, from outdoor ambient temperatures to the ®rst cell of the ambient CO2 tunnel (ambient t...

15 صفحه اولPhotosynthetic responses of rice - and soybean to elevated CO2 , and temperature
Carbon dioxide and other 'greenhouse' gases continue to increase in the earth's atmosphere at a relatively rapid rate. Because of this, atmospheric general circulation models predict substantial increases in atmospheric temperature and changes in regional precipitation patterns by the later part of this century.. . Scientific evidence already indicates that the earth's near-surface temperature ...
