Priana apricot trees usually carry a very heavy crop of small fruit and reduction of quality. Fruit hand thinning is hard activity in a short period of time and a reliable good way to low crop level and enhance the fruit quality to be acceptable with the prices which exporting is too difficult to apricot fruits. Consequently, hand-thinning of Priana cv. fruits were applied on 5 years old trees for two times through fruit set or Pit hardening. In both times there were three intensity of thinning

... were done 40%, 50%, 60% during two consecutive years 2016 and 2017.

However the 60% thinning will provide luxury fruits, especially in terms of size, but this will be achieved with high reduction in crop yield. While, control (without thinning) treatment for thinning was given despite a high yield, but the quality of the physical or chemical fruits was very low.
