Other claims from this paper (16)
- Association Higher seed nitrogen was associated with increased seedling growth.
- Association Higher seed nitrogen was associated with fewer nitrogen deficiency symptoms.
- Association Leaf expansion was more severely restricted in soybean lines with lower seed nitrogen.
- Association Leaf initiation was more severely restricted in soybean lines with lower seed nitrogen.
- Mechanism Depressed canopy development primarily led to decreased shoot:root growth ratios in all three lines.
- Association The line with the lowest seed nitrogen had a higher shoot:root ratio as nitrogen stress progressed.
- Observation Shoot and root growth changes differed from previous nitrogen deficiency studies.
- Association Growth recovery rates were correlated with initial seed nitrogen content after nitrogen resupply.
- Observation Leaf initiation rates rapidly responded to external nitrogen with no delay.
- Association Leaf expansion during nitrogen stress recovery depended on the leaf developmental stage.
- Observation Most nitrogen left cotyledons within 12 days in three soybean lines.
- Observation Nitrogen mobilization finished before measurable seedling growth differences.
- Association External nitrogen presence lowered mobilization rates.
- Observation Differences in proteolysis of glycinin and beta-conglycnin between nitrogen treatments were not detectable.
- Association Storage protein content was proportional to seed nitrogen content.
- Association Proteolysis rates were proportional to seed nitrogen content.
