Abstract
Cherries are becoming a more and more important fruit plant in Poland and the requirements for fruit quality are increasing. This enforces the use of new technologies. One is the thinning of flowers or fruitlets. In the study the spraying with 10, 20 and 30 g × dm-3 corn oil and olive oil was used. The used preparations variously influenced the studied cultivars: ‘Kordia’ and ‘Regina’. The fruit mass from trees ‘Kordia’ sprayed with 20 g × dm-3 of olive oil was much higher than from control. Fruits from cherry ‘Regina’ had a significant smaller mass of fruit and the content of the extract, sugars and anthocyanins after using corn oil at 30 g × dm-3.
