S. C. CLIFFORD; I. M. STRONACH; A. D. MOHAMED; et al. Journal of Experimental Botany 1993. doi:10.1093/jxb/44.12.1763

Other claims from this paper (12)

Intervention effect Elevated CO2 increased the maximum rate of net photosynthesis in groundnut by up to 40% relative to 350 ppmv.
Intervention effect Elevated CO2 increased the conversion coefficient for intercepted radiation by 30% in well-irrigated groundnut.
Intervention effect Elevated CO2 increased the conversion coefficient for intercepted radiation by 94% on a drying soil profile.
Intervention effect Elevated CO2 increased dry matter accumulation by 16% in well-watered groundnut.
Intervention effect Elevated CO2 increased pod yield by 25% in well-watered groundnut.
Intervention effect Under severe water stress, elevated CO2 increased dry matter production by 112% in groundnut.
Intervention effect Under severe water stress, elevated CO2 gave higher groundnut pod yield (1·34t ha−1) than 350 ppmv CO2 (0·22 t ha-1).
Intervention effect Harvest index was unaffected by CO2 treatment in groundnut.
Intervention effect After withholding irrigation, elevated CO2 maintained significantly less negative leaf water potentials than ambient CO2 for the rest of the season.
Intervention effect In well-watered groundnut, dry matter allocation among leaves, stems, roots and pods was similar under both CO2 treatments.
Intervention effect On a drying soil profile, groundnut at 350 ppmv CO2 shifted dry matter allocation towards root development earlier than at 700 ppmv CO2.
Mechanism The primary effects of elevated CO2 on groundnut growth and yield are mediated by a higher conversion coefficient for intercepted radiation and prolonged maintenance of higher leaf water potentials.
