Verbatim
e2“under low N supply, the maximum carboxylation rate ( V cmax ), the maximum electron transport rate ( J max ) and the rate of triose phosphate utilisation (TPU) were significantly downregulated by e [CO 2 ] from the first to the second generation, but recovered in the third generation”
e0“five wheat cultivars were grown under either ambient ( a [CO 2 ], 400 ppm) or elevated ( e [CO 2 ], 800 ppm) CO 2 concentration for three consecutive generations (G1 to G3)”

Other claims from this paper (8)
- Intervention effect Elevated CO2 stimulated the photosynthetic rate of wheat at both N levels.
- Intervention effect Elevated CO2 reduced stomatal conductance, transpiration rate and leaf N concentration of wheat at both N levels.
- Intervention effect Elevated CO2 enhanced water use efficiency and photosynthetic N use efficiency of wheat at both N levels.
- Intervention effect Under low N supply, elevated CO2 significantly downregulated the maximum carboxylation rate, maximum electron transport rate and triose phosphate utilisation of wheat from the first to the second generation.
- Intervention effect At high N levels, photosynthetic acclimation of wheat to elevated CO2 diminished with successive generations.
- Intervention effect At high N levels, the maximum carboxylation rate, maximum electron transport rate and triose phosphate utilisation of wheat increased under elevated CO2 in the third generation.
- Intervention effect Cultivar 325Jimai showed better photosynthetic performance under elevated CO2 over the three generations.
- Intervention effect Cultivar 02-1Shiluan appeared to be more inhibited by CO2 elevation in the long term.
