Other claims from this paper (10)
- Intervention effect Nitrogen withholding lowered blade nitrogen and chlorophyll percentages.
- Intervention effect Nitrogen withholding changed fixation-product composition.
- Intervention effect Nitrogen deprivation reduced attached-blade-to-stalk photosynthate translocation.
- Intervention effect Nitrogen deficiency reduced the percentage of total activity translocated.
- Intervention effect Nitrogen deficiency reduced transport velocity.
- Intervention effect Nitrogen-deprived blades retained more labeled sucrose in the fed part.
- Intervention effect Nitrogen-deprived blades retained more labeled sucrose below the fed part.
- Intervention effect Nitrogen-deprived blades sent less labeled sucrose to the leaf sheath.
- Intervention effect Nitrogen withholding had no effect on transport in detached blades.
- Mechanism The authors suggest whole-plant growth effects may indirectly explain reduced translocation.
