Other claims from this paper (9)
- Intervention effect Individual fruit fresh weight was not affected by treatments.
- Intervention effect Fruit dry weight and dry-to-fresh weight ratio were higher in girdled plants without primocanes.
- Intervention effect Girdling and primocane presence did not affect dry weight allocation to canes.
- Intervention effect Root dry weight was higher with girdling and primocanes than without both.
- Mechanism Primocanes appear to supply carbon to roots during fruiting.
- Mechanism Roots appear to mobilize carbon to floricanes.
- Mechanism Roots appear to provide a carbon translocation pathway from primocanes to floricanes.
- Mechanism Suppressed primocane growth appears to mobilize root carbon for floricane development.
- Intervention effect Restricted root-to-floricane carbon flow significantly decreases fruit number and yield.
