“…Little is known still about the mechanisms determining the number of flowers per reproductive bud. Our results, as well as other research, note the effect of rootstocks and cultivars on this parameter (Tabakov et al 2015;Dziedzic et al 2019). In addition, in the present study, flower buds on 1-yearold shoots formed fewer flowers per bud, compared to spurs on 2-to 4-year-old sections of the branch.…”

“…The same trend was observed in the present study, supported by an adverse correlation (R 2 = −0.630, p < 0.01) between the number of flower buds per 1-year-old shoot and spur density. Other studies also report rather inconsistent patterns regarding spur density on scion-rootstock combinations of varying vigour (Tabakov et al 2015;Dziedzic et al 2019).…”

To maintain the high yields and fruit quality necessary for profitability of sweet cherry production, it is important to consider precision crop load and canopy management techniques during limb renewal. The effects of branch section age, rootstock, and cultivar on spur and flower density and fruit quality have been discussed in previous studies, but most of them focus on a limited range of fruiting wood ages and scion-rootstock combinations. This study aims to analyse the processes of sweet cherry productivity and fruit size formation on a wide range of wood age to determine the limit after which branch preservation is not sustainable, and to evaluate the influence of rootstocks and cultivars on these parameters. The results indicate that wood age is one of the main drivers of productivity formation in cherry. The highest flower density was observed on 3-year-old branch sections – 324 flowers per linear m, due to high spur density, number of reproductive buds per spur and flowers per bud. Productivity on 2-year-old wood was also good (256 flowers per linear m), while a sharp decline in flower density was noted on 4- and 5-year-old wood. The largest fruits were formed on young branch sections, with a significant decline in fruit weight and diameter on 4- and 5-year-old sections. Rootstock vigour had a bigger effect on floral organ induction on 1-year-old shoots, than on spurs. Based on the results, it is advisable to regularly renew lateral branches older than 3 years to maintain high yield efficiency and fruit quality.

“…Thus, not only the annual harvest is lost, but also the health of the trees. Determining of the frost damage to a tree is difficult because it depends on many factors, such as variety characteritics, intensity of pruning, duration of exposure to low temperature, speed of freezing/thawing, resting stages of the tree during freezing [Chmielewski et al, 2018;Dziedzic et al, 2019]. However, according to a number of scientists [Kaya et al, 2021;Cittadini et al, 2006;Shubenko, 2018] the cold resistance of cherry and sour cherry varieties is genetically determined and varies between varieties.…”

The article presents the study results of the frost resistance of sweet cherry varieties of different ripening periods under artificial freezing. The damage degree of various tissues of one-and two-year-old wood, as well as fruit formations, was analyzed. In the group of early-ripening and late-ripening varieties, a significant resistance of the bark to the effect of low temperature was found, the average damage score was 0.7. Among late-ripening cherry varieties Drogana yellow had low-temperature damage to one-year-old wood, while no negative effect on the wood was observed for the Amazonka variety. The highest overall degree of freezing of one-year wood was observed for the varieties Mliivska yellow and Drogana yellow, the lowest values were obtained for the varieties Meotida, Mirage and Amazonka. Dispersion analysis based on a combination of factors confirmed the highest degree of wood freezing for the Mliivska yellow and Drogana yellow varieties. Among the early-ripening varieties, the two-year-old wood froze the most in trees of the Dar Mlieva variety, where the highest degree of damage to the tissues of the bark, cambium, and wood was observed. The least tissue damage was in the Mliivska yellow variety, however, its core had the maximum damage not only within the group, but also among all the studied varieties. By artificial freezing in laboratory conditions, it was established that the highest frost resistance of annual and perennial wood is characteristic of the early ripening variety Zoryana, medium ripening Meotida and late ripening Amazonka. As a result of laboratory freezing, the frost resistance of fruiting bodies did not exceed 2.2 points. The fruiting formations of the Drogana yellow exceeded all the studied varieties in terms of the level of damage. High resistance to low temperatures was shown by the fruiting formations of the varieties Zoryana, Mirage and, especially, Alyonushka. The damage level of other pomological varieties was in the range of 1.9-2.25 points. The most negative effect of low temperatures was caused on flower germs.

“…For the sweet cherry culture, at least two types of stress factors have been identified: these are abnormally low temperatures during the dormant period and annual spring frosts during the flowering period [1,4,13]. Some researchers, one of the possible conditions for the full realization of the productivity of sweet cherry, consider varietal resistance to the effects of abnormal frosts at the beginning of winter, when the level of yield loss can reach 80-100% [14,15]. There is an opinion that the third and fourth components of the winter hardiness of fruit plants are the main ones.…”

The main stress factors for sweet cherries in the Krasnodar region are: late return frosts and early exposure to frost after a warm autumn. 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%. 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%. Under favorable weather conditions, 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%. Mathematical analysis showed a high correlation (R2 = 0.97) of the yield of varieties from the abnormal temperatures in March and the degree of exposure to stress, i.e. damage to generative organs (R2 = 0.9). Domestic varieties Alaya, Sashenka and Volshebnitsa, can be recommended for creating sustainable plantations in the south of Russia.
