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 Cool days and warm nights reduced sweetpotato storage root yield by about 50% in Experiment 1.
Intervention effect With increased plant population, sweetpotato storage root yield under inverse temperatures was similar to controls in Experiment 2.
Intervention effect Sweetpotato storage root yield was similar to controls when cool day and warm night temperatures began 6-8 weeks after planting.
Intervention effect Inverted temperature treatments substantially reduced sweetpotato canopy height.
Intervention effect Inverse temperature controlled sweetpotato canopy height whether begun at planting or 6-8 weeks later.

Intervention effect For NO3−, prolonged darkness caused a large decrease in influx.
Intervention effect For NO3−, prolonged darkness caused a smaller increase in efflux.
Observation Estimated translocatory flux of NO3− was 0.3-2.0 umol per h per g.
Observation Estimated translocatory flux of NH4+ was 0.03-0.4 umol per h per g.
