Other claims from this paper (12)

Intervention effect In tomato, 14CO2 fixation at normal CO2 was slightly decreased after 2 hours at 80 ppm CO2.
Association The tomato after-effect of low-CO2 experience appeared only under low CO2 concentration combined with a certain light intensity.

Intervention effect In cucumber, total 14C fixation was clearly decreased at very low CO2 concentration.
Intervention effect Downward translocation of 14C-assimilates to the roots was restricted more in cucumber than in tomato at 80 ppm CO2 in the light.
Observation In cucumber during normal photosynthesis in the light, translocation of assimilates from leaves into the roots was considerably restricted.
Observation Tomato plants had a CO2 compensation concentration of 38±2 ppm in a closed system at 20,000 lux.
Observation Cucumber plants had a CO2 compensation concentration of 65±4 ppm in a closed system at 20,000 lux.
Observation CO2 evolved through respiration into CO2-free air was higher in cucumber.
Intervention effect Tomato plants kept at 80 ppm CO2 for 2 hours had lower respiratory activity in the roots.
Intervention effect Low-CO2 experience caused a considerable decrease in phosphorus uptake through tomato roots.
Intervention effect The same CO2 treatment of tomato plants caused a considerable decrease in net assimilation rate.
