Other claims from this paper (9)
- Intervention effect Autumn nitrogen supply delayed apple leaf senescence.
- Intervention effect Autumn nitrogen supply reduced nitrogen withdrawn from apple leaves from 156 to 91 mg N per plant.
- Observation RUBISCO loss accounted for 83–87% of soluble protein nitrogen lost during apple leaf senescence.
- Observation RUBISCO was preferentially lost compared with other soluble apple leaf proteins during senescence.
- Observation Nitrogen remobilized from perennial apple stems and roots in spring was used predominantly for leaf growth.
- Association The amount of nitrogen remobilized in apple depended on the size of the nitrogen store.
- Intervention effect Current nitrogen supply did not affect the amount of nitrogen remobilized in apple.
- Observation Autumn RUBISCO degradation accounted for 32% to 48% of nitrogen subsequently remobilized for apple leaf growth.
- Mechanism The authors suggest RUBISCO serves as a summer nitrogen store in apple trees.
