“…WUE response to elevated CO 2 concentration might diverse with changed precipitation. In the present study, WUE was significantly higher under elevated CO 2 consistent with results of previous studies (Kaminski et al, ; Long, Ainsworth, Rogers, & Ort, ), and this change occurred mainly due to a higher A net (Albert et al, ; Duan et al, ). These findings suggested that elevated CO 2 did lead to water savings at the leaf level of S. baicalensis in our study.…”

Elevated atmospheric CO2 concentration and simultaneous precipitation change affect plant physiology and growth either directly or indirectly. The main objective of this study was to investigate the effects of elevated CO2 and precipitation change, alone or in combination, on photosynthesis and growth in Stipa baicalensis under differential growth phases. Elevated CO2 showed a consistently significant increase in net photosynthesis rate (Anet), water‐use efficiency (WUE), leaf area and biomass. However, elevated CO2 did not mitigate the negative effects of severe drought stress. Increase of Anet under elevated CO2 attributed to Ci in the early growth phase, but WUE and Rubisco carboxylation (Vcmax) was the main inductor in the later growth phase. Effects of elevated CO2 on S. baicalensis were closely associated with precipitation conditions, and the influence on photosynthetic capacity was also related to the growth phase. Drought significantly reduced Anet in June and August, increased WUE in June but did not show effect in August. Precipitation enhancement was beneficial to leaf area and biomass accumulation. Elevated CO2 and enhanced precipitation in combination promoted Anet by 158% and 93.4% in June and August, respectively; moreover, their interaction increased the total biomass by 44.4%. Our results suggested that the elevated CO2 concentration in the future might be beneficial to the growth of S. baicalensis, but elevated CO2 influence on S. baicalensis might strongly depend on precipitation conditions and the growth phase.

“…These small declines were generally below experimentally reported values which ranged between −3% and −12% for well‐managed potato under high C conditions (Magliulo et al ., ; Fleisher et al ., , ), although some controlled environment experiments indicated a slight increase in water use (Wheeler et al ., ). Harvest index and carbon allocation were reported to shift preferentially to tubers under higher C (Donnelly et al ., ; Lawson et al ., ; Fleisher et al ., , ; Högy & Fangmeier, ; Kaminski et al ., ), but such trends were not reproduced in the median model responses at any C level (Table ).…”

“…These yield responses to C compared favorably with experimental data obtained for potato over a broad range of C levels (e.g., Schapendonk et al ., ; Donnelly et al ., ; Vandermeiren et al ., ; Finnan et al ., ; Conn & Cochran, ; Högy & Fangmeier, ; Kimball, ; Fleisher et al ., ; Kaminski et al ., ). Median relative ET declined between 0.3% and 6% across sites representing a decrease of −0.4, −4.8, −6.6, and −4.6 mm 100 ppm −1 with respect to Bolivia, Burundi, Denmark, and United States.…”

“…The crop is frequently categorized as drought and T sensitive, with yield declines occurring at moderate levels of soil moisture depletion (Borah & Milthorpe, 1962;Van Dam et al, 1996) and with cooler optimal T for yield and rate processes as compared with other economically important commodities (Van Loon, 1981;Stalham & Allen, 2004;Timlin et al, 2006). Similar to other plants with a C3 biochemical photosynthetic pathway, potato exhibits positive responses to increasing C when other cultural factors are nonlimiting (e.g., Baker & Allen, 1994;Finnan et al, 2005;Kaminski et al, 2014). Thus, potato crop models intended to evaluate impacts of climate change from a global perspective must be capable of simulating growth and development sensitivities, including associated temperature and drought stresses, to varying C, T, and W levels across a broad range of genetic and management factors.…”

A potato crop multimodel assessment was conducted to quantify variation among models and evaluate responses to climate change. Nine modeling groups simulated agronomic and climatic responses at low-input (Chinoli, Bolivia and Gisozi, Burundi)- and high-input (Jyndevad, Denmark and Washington, United States) management sites. Two calibration stages were explored, partial (P1), where experimental dry matter data were not provided, and full (P2). The median model ensemble response outperformed any single model in terms of replicating observed yield across all locations. Uncertainty in simulated yield decreased from 38% to 20% between P1 and P2. Model uncertainty increased with interannual variability, and predictions for all agronomic variables were significantly different from one model to another (P < 0.001). Uncertainty averaged 15% higher for low- vs. high-input sites, with larger differences observed for evapotranspiration (ET), nitrogen uptake, and water use efficiency as compared to dry matter. A minimum of five partial, or three full, calibrated models was required for an ensemble approach to keep variability below that of common field variation. Model variation was not influenced by change in carbon dioxide (C), but increased as much as 41% and 23% for yield and ET, respectively, as temperature (T) or rainfall (W) moved away from historical levels. Increases in T accounted for the highest amount of uncertainty, suggesting that methods and parameters for T sensitivity represent a considerable unknown among models. Using median model ensemble values, yield increased on average 6% per 100-ppm C, declined 4.6% per °C, and declined 2% for every 10% decrease in rainfall (for nonirrigated sites). Differences in predictions due to model representation of light utilization were significant (P < 0.01). These are the first reported results quantifying uncertainty for tuber/root crops and suggest modeling assessments of climate change impact on potato may be improved using an ensemble approach.

“…This suggests elevated CO 2 promotes Pn by increasing light capture and CO 2 fixation. Furthermore, it can reduce water consumption, thereby increasing dry matter production and yield via increased plant‐level water use efficiency (WUE plant ; Kaminski et al , Pazzagli et al , da Silva et al ). Moreover, elevated CO 2 also increases Pn while decreasing Tr, therefore increasing leaf‐level water use efficiency (WUE leaf ; Mamatha et al , Li et al ).…”

Carbon dioxide concentration (CO2) and light intensity are known to play important roles in plant growth and carbon assimilation. Nevertheless, the underlying physiological mechanisms have not yet been fully explored. Tomato seedlings (Solanum lycopersicum Mill. cv. Jingpeng No. 1) were exposed to two levels of CO2 and three levels of light intensity and the effects on growth, leaf gas exchange and water use efficiency were investigated. Elevated CO2 and increased light intensity promoted growth, dry matter accumulation and pigment concentration and together the seedling health index. Elevated CO2 had no significant effect on leaf nitrogen content but did significantly upregulate Calvin cycle enzyme activity. Increased CO2 and light intensity promoted photosynthesis, both on a leaf‐area basis and on a chlorophyll basis. Increased CO2 also increased light‐saturated maximum photosynthetic rate, apparent quantum efficiency and carboxylation efficiency and, together with increased light intensity, it raised photosynthetic capacity. However, increased CO2 reduced transpiration and water consumption across different levels of light intensity, thus significantly increasing both leaf‐level and plant‐level water use efficiency. Among the range of treatments imposed, the combination of increased CO2 (800 µmol CO2 mol−1) and high light intensity (400 µmol m−2 s−1) resulted in optimal growth and carbon assimilation. We conclude that the combination of increased CO2 and increased light intensity worked synergistically to promote growth, photosynthetic capacity and water use efficiency by upregulation of pigment concentration, Calvin cycle enzyme activity, light energy use and CO2 fixation. Increased CO2 also lowered transpiration and hence water usage.
