Abstract
Blossom thinners affected fruit set, fruit quality, and yield of ‘Delicious’, ‘Rome’, ‘Fuji’, and ‘Jonathan’ apples (Malus domestica Bork.). Most of tested chemicals reduced fruit set in the tested apple cultivars, with the higher concentrations. Ammonium thiosulfate (ATS) and hydrogen cyanamide (Dormex) significantly reduced fruit set of ‘Red Delicious’ apples. Double applications of these chemicals often had more blossom thinning effect than single application. Double applications of ATS at a rate of 15 mLㆍL?¹ or single application of at a rate of 25 mLㆍL?¹ reduced fruit set of ‘Fuji’ apples at satisfactory levels. Double applications of ATS at a rate of 25 mLㆍL?¹ caused excess thinning and could not be used for apples. A single application of Dormex at rate of 3.12 mLㆍL?¹ significantly reduced fruit set of ‘Rome’ apples. However, double application of endothalic acid caused severe fruit marking in ‘Rome’ apples.
