Continuing increases in atmospheric carbon dioxide concentration (CO 2 ) will likely be accompanied by global warming. Our research objectives were (a) to determine the effects of season‐long exposure to daytime maximum/nighttime minimum temperatures of 32/22, 36/26, 40/30 and 44/34°C at ambient (350 μmol mol −1 ) and elevated (700 μmol mol −1 ) CO 2 on reproductive processes and yield of peanut, and (b) to evaluate whether th...

It is important to quantify and understand the consequences of elevated temperature and carbon dioxide (CO 2 ) on reproductive processes and yield to develop suitable agronomic or genetic management for future climates. The objectives of this research work were (a) to quantify the effects of elevated temperature and CO 2 on photosynthesis, pollen production, pollen viability, seed‐set, seed number, seeds per pod, seed size, se...

This study was conducted to determine the response in leaf growth and gas exchange of soybean ( Glycine max Merr.) to the combined effects of water deficits and carbon dioxide (CO 2 ) enrichment. Plants grown in pots were allowed to develop initially in a glasshouse under ambient CO 2 and well‐watered conditions. Four‐week old plants were transferred into two different glasshouses with either ambient (360 μmol mol ‐1 ) or elev...

Projections of future climate change include a strong likelihood of a doubling of current atmospheric carbon dioxide concentration ([ CO 2 ]) and possible shifts in precipitation patterns. Drought stress is a major environmental limitation for crop growth and yield and is common in rainfed rice production systems. This study was conducted to determine the growth and grain yield responses of rice to drought stress under [CO 2 ]...

Future climate change is projected to include a strong likelihood of continued increases in atmospheric carbon dioxide concentration ([CO 2 ]) and possible shifts in precipitation patterns. Due mainly to uncertainties in the timing and amounts of monsoonal rainfall, drought is common in rainfed rice production systems. The objectives of this study were to quantify the effects and possible interactions of [CO 2 ] and drought st...
