Other claims from this paper (17)

Intervention effect CO2 enrichment increased total leaf area and dry weight during reproductive growth.
Intervention effect Water stress inhibited soybean growth at all CO2 levels.
Intervention effect The relative enhancement of growth by CO2 enrichment was greater under water-stressed conditions than under well-watered conditions.
Intervention effect Water-stressed plants grown under 946 CO2 were larger than well-watered plants grown under 349 CO2.
Intervention effect Reproductive yield increases under elevated CO2 came from increased seed number.
Intervention effect Reproductive yield increases under elevated CO2 did not come from larger seeds.
Intervention effect Water stress reduced soybean yield.
Intervention effect The relative increase in seed number under elevated CO2 was greater for water-stressed plants.
Mechanism A phosphorus deficiency may have restricted the seed dry weight response to elevated CO2.

Other claims from this paper (5)

Association The disappearance of ROS from the elongation zone coincides with arrest of root elongation under low P.
Intervention effect P-starvation decreased the ascorbic acid level in roots.
Intervention effect Feeding P-deficient plants with ascorbic acid stimulated mitotic activity in the primary root meristem.
Intervention effect Feeding P-deficient plants with ascorbic acid partly reversed the inhibition of root growth imposed by low P.
