Abstract
Thinning has a great influence on the number and quality of apple (Malus domestica Borkh.) fruits.
If thinning is not performed, a larger portion of fruits drop by themselves during June drop. What exactly triggers this phenomenon is not entirely known.
We tried to determine how the fruitlet position in the fruit cluster influences their primary and secondary metabolite content.
We determined the amount of sugars, organic acids, anthocyanins, flavanols, flavonols, hydroxycinnamic acids, dihydrochalcone and total phenolic content.
Position of fruitlets in the fruit cluster influenced the content of metabolites.
The highest positioned fruit has the highest content of sugars and organic acids, but secondary metabolites content was higher in in some fruits positioned lower in the fruit cluster.
