e0“Applying foliar sprays to on-year trees of succinic acid-2,2-dimethylhydrazide (aminozide) and naphthaleneacetic acid (NAA) caused cessation of growth accompanied by a significant increase in the spur starch content despite the presence of fruits.”

Other claims from this paper (7)
- Observation Non-bearing spurs contained significantly more starch than fruit-bearing spurs in four years.
- Observation Fruit-bearing spur starch content fell dramatically at the end of June, 5 to 6 weeks after full bloom.
- Intervention effect Aminozide spray stopped growth and significantly increased spur starch despite fruit presence.
- Intervention effect Treated trees had doubled flowering.
- Intervention effect GA3 on off-year trees reduced spur starch.
- Mechanism Authors conclude hormones from developing seeds lower spur starch.
- Mechanism Authors consider high spur starch an indicator of metabolic processes linked to low auxin and gibberellins, not a direct flower-initiation cause.
