Other claims from this paper (7)
- Observation An increasing share of apple fruit vascular bundles failed to stain as the season progressed.
- Association Bundle failure increased with distance from the stalk end of apple fruit.
- Observation Primary bundle conductance decreased earlier in Braeburn than Granny Smith apples.
- Observation Apple fruit vascular bundle xylem showed substantial damage.
- Mechanism The authors attribute xylem dysfunction to physical disruption caused by flesh expansion.
- Mechanism The authors attribute relative apple fruit calcium deficiency to progressive xylem conductance breakdown caused by growth damage.
- Mechanism Earlier xylem dysfunction in the cultivar more prone to bitter pit suggests fruit growth dynamics may control calcium-related disorders.
