Other claims from this paper (19)
- Intervention effect Benzyladenine effectively thinned McIntosh apple fruit, including when shoot tips were or were not removed.
- Intervention effect Benzyladenine thinned fruit only when one leaf per fruit was on the girdled small fruiting branch, not when more than two leaves were present.
- Intervention effect Benzyladenine increased fruit size and caused seed abortion in McIntosh apples.
- Intervention effect Benzyladenine increased the first fruit abscission peak in McIntosh apples.
- Intervention effect Approximately half of the existing fruit abscised from BA-treated trees between 10 and 14 days, against one fourth from control trees.
- Association Seed number per fruit was lower in abscising fruit than in persisting fruit, regardless of BA treatment.
- Intervention effect Benzyladenine application increased the seed number of abscising fruit linearly.
- Intervention effect BA applied directly to the fruit enhanced translocation of C-sorbitol from leaves to fruit.
- Intervention effect BA applied directly to the leaves did not enhance translocation to the fruit.
- Intervention effect Net photosynthesis decreased when the temperature following BA application was high (30 degrees C).
- Intervention effect Dark respiration increased when the temperature following BA application was high.
- Observation Total nonstructural carbohydrates, total soluble sugars and reducing sugars in the leaves decreased over the 12 or 13 day observation period, regardless of BA.
- Observation Starch in the leaves decreased over the 12 or 13 day observation period.
- Intervention effect BA application further lowered the carbohydrate levels.
- Association Abscising fruit had higher reducing sugars, total soluble sugars, starch and total nonstructural carbohydrates.
- Observation Fruit abscission in June drop showed two distinguishable peaks, regardless of BA treatment.
- Intervention effect Fruit from BA-treated trees had carbohydrate levels similar to untreated control trees.
- Intervention effect Foliar application of 5% sorbitol solution had no effect on fruit set.
- Intervention effect Removing the bourse shoot tip increased fruit set, regardless of BA treatment.
