Abstract
Elevated atmospheric CO2 is projected to affect plant growth and crop quality, but its impact on rice, particularly on photosynthesis and grain quality, remains under investigation. This study uses open-top chambers to simulate elevated CO2 conditions and assesses their effects on rice photosynthesis, chlorophyll content, and grain quality under controlled environments. Results indicated a significant increase in photosynthetic rate and chlorophyll concentration in rice plants exposed to higher CO2 levels. However, while grain yield was enhanced, there was a notable reduction in the nutritional quality of the grains, with lower protein content. This research provides insights into the potential effects of climate change on rice production and quality.
