Altering Source‐Sink Relationships in Prolific Maize Hybrids: Consequences for Nitrogen Uptake and Remobilization

W. L. Pan; J. J. Camberato; R. H. Moll; et al. Crop Science 1995. doi:10.2135/cropsci1995.0011183x003500030034x

Other claims from this paper (9)

Association Fully pollinated high-yielding maize hybrids had 74% more grain weight than low-yielding hybrids.
Intervention effect A high-yielding maize hybrid had 71% more G w under full pollination than with only apical ears pollinated.
Intervention effect Limiting pollination had little effect on low-yielding maize hybrids.
Intervention effect The composite [T wa − G w ] was greater at low plant density.
Intervention effect The composite [T wa − G w ] was greater with limited pollination.
Association The composite [T wa − G w ] was positively related to N a uptake after anthesis.
Association Greater kernel weight and number were positively correlated with post-anthesis DM accumulation in maize.
Observation High-yielding maize hybrids maintained T a and Na during multiple ear development.
Mechanism Nitrogen uptake after anthesis is regulated by ear sink size relative to photosynthate supply, according to the authors.
