Fruits parameters of bird cherry cultivars

The fruit indicators of bird cherry cultivars in the Botanical Garden-Institute of VSUT (Yoshkar-Ola, the Mari El Republic) are given. In the abnormally dry and hot conditions of 2021, the bird cherry trees formed smaller fruits. Varieties with large and small fruits are distinguished. Fruit mass was characterized by the greatest inter-variety variability, fruit sizes were less variable, and the pulp content in fruits was the most stable. There was no significant effect of the varietal specificity factor on the fruit parameters.
