Other claims from this paper (9)
- Observation Most early embryo-axis dry-weight gain occurred in the hypocotyl.
- Observation Epicotyl size and dry weight did not rise rapidly until days four to five.
- Intervention effect Hypocotyl dry weights were similar under normal and limiting carbon dioxide through day 11.
- Observation By day 13 hypocotyl dry weight continued increasing in normal carbon dioxide.
- Intervention effect By day 13 hypocotyl dry weight decreased under limiting carbon dioxide.
- Intervention effect Carbon dioxide treatment did not produce significantly different cotyledon reserve-utilization patterns.
- Observation Seedlings used cotyledonary carbohydrates and lipids before proteins under both atmospheres.
- Observation Cotyledon reserves supported soybean seedling development until about day nine.
- Observation Net carbon dioxide uptake first occurred between days nine and eleven in normal atmosphere.
