Other claims from this paper (19)
- Intervention effect Under FACE, heading in rice occurred 3-5 days earlier than under ambient CO2.
- Intervention effect Under FACE, maturity in rice occurred 6-9 days earlier than under ambient CO2.
- Intervention effect FACE increased rice grain yield by 12.8% relative to ambient CO2; no CO2xN interaction was detected for most parameters.
- Intervention effect FACE increased panicle number per square meter by 19% in rice, attributed to faster tillering occurrence.
- Intervention effect FACE reduced spikelet number per panicle in rice by 8%; differentiated spikelets per panicle showed no change.
- Intervention effect FACE significantly increased degenerated spikelets per panicle in rice by 52%.
- Intervention effect FACE stimulated dry matter accumulation at harvest in rice by 16%, more than grain yield (average 13%).
- Intervention effect FACE reduced harvest index in rice by 3%.
- Intervention effect FACE reduced shoot N concentration in rice by 7% at grain maturity.
- Intervention effect FACE increased P concentration in rice by 14% at grain maturity.
- Intervention effect FACE increased N use efficiency in rice.
- Intervention effect FACE reduced P use efficiency in rice.
- Intervention effect FACE increased shoot N uptake in rice by 9% at harvest.
- Intervention effect FACE increased P uptake in rice by 33% at harvest.
- Intervention effect Under FACE, per-plant cumulative root volume, root dry weight, adventitious root length and adventitious root number of rice increased at heading.
- Intervention effect FACE significantly reduced total surface area, active adsorption area and root oxidation activity per unit root dry weight in rice.
- Intervention effect FACE drastically deteriorated processing suitability and appearance quality of rice grain.
- Intervention effect FACE negatively influenced the nutritive value of rice grain, due to reduced grain protein and Cu concentration.
- Intervention effect FACE resulted in better eating/cooking quality of rice grain.
