Title

Soybean growth response to water supply and atmospheric carbon dioxide enrichment

Stephen A. Prior; Hugo H. Rogers Journal of Plant Nutrition 1995. doi:10.1080/01904169509364927

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.
Intervention effect Mean relative growth rate and mean net assimilation rate increased with CO2 concentration in the first interval (5 to 14 days after planting).
Intervention effect The increase of mean RGR and mean NAR with CO2 diminished with time after the first interval.
Mechanism The direct effect of NAR on growth at the second interval was offset by lower leaf area ratio.
Intervention effect Leaf area ratio was greater for water-stressed plants.
Intervention effect The response of RGR to CO2 was similar under both water treatments.
Intervention effect The RGR of water-stressed plants remained constant across CO2 treatments in the third interval.
Intervention effect Under well-watered conditions, RGR decreased under CO2-enriched conditions in the third interval.
Intervention effect Leaf weight ratio was unaffected by CO2.

Intervention effect Alanine symporter activity did not change with sucrose treatment.
Intervention effect Glucose transporter activity did not change with sucrose treatment.
Observation Decreased sucrose symporter activity was detectable after 8 h.
Observation The sucrose symporter activity decline reached a maximum by 24 h.
Observation Symporter message levels decreased.
Observation Changing osmotic conditions did not account for the sucrose responses.
Intervention effect Equal molar concentrations of hexoses did not elicit the sucrose response.
