Mathematical analysis showed a high correlation (R 2 = 0.97) of the yield of varieties from the abnormal temperatures in March and the degree of exposure to stress, i.e. in the absence of any type of stress, the yield of sweet cherry varieties reached 40.5 kg/tree or 27 t/ha, and the implementation of the production potential − 57.8%. The early impact of frost after a warm autumn, the death of the generative organs of sweet cherry was 90%, the realization of the productive potential − 5.6%. Against the background of late return frosts, the death of the generative organs of sweet cherry was 95%, the realization of the productive potential − 3.3% after early spring frosts, freezing of cherry fruit buds was 30%, the realization of productive potential − 47.8%. ![]() * Corresponding author: main stress factors for sweet cherries in the Krasnodar region are: late return frosts and early exposure to frost after a warm autumn.
