Six sweet cherry cultivars and two advanced selections of Gisela 5 rootstock were tested in 2015-2021 at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry. Fruit trees were planted at distances of 4.5 x 2.5 m and trained as spindles. Orchard floor management included frequently mown grass in alleyways with herbicide strips along tree rows. Cultivars ‘Mindaugė’ and ‘Irema BS’ were the most vigorous at the end of the seventh leaf. Their trunk diameter achieved 11.6 cm. The ‘Merchant’ cultivar had the smallest trunk diameter—9.3 cm. The average yield in 2018-2021 ranged from 2.75 t/ha for ‘Vega’ to 8.73 t/ha for ‘Regina’. Cultivars ‘Regina’, ‘Sunburst’, ‘Irema BS’ and ‘Merchant’ had the highest cumulative yield efficiency of 0.440-0.503 kg/cm2 with respect to the trunk cross-section area (TCSA). The least productive cultivar ‘Vega’ produced fruits of the highest average weight—9.9 g. Fruits of ‘Regina’ and ‘Sunburst’ were large as well—8.8-9.1 g. ‘Irema BS’ fruits had the highest soluble solids content (SSC)—20.2%. The lowest SSC was recorded in ‘Merchant’ and ‘Sunburst’ fruits—14.7-15.8%. The yield of advanced selection, No. 102, equaled to the yield of cv. ‘Regina’. No. 102 had a high fruit weight, and fruits were distinguished by attractiveness and taste.

The competitiveness of fresh fruit in the modern market substantially depends on sensory quality indicators. Sweet cherries are a top fruit that is highly valued by consumers due to their taste and visual attractiveness. For the growing demand for fruits on the European market, it is important to examine the sensory properties of cherry fruits in combination with their weight and diameter. The purpose of the study was to substantiate sensory indicators for examining the quality of cherry fruits of different maturation periods and selecting the most competitive varieties for the sustainable provision of fresh fruit in accordance with the requirements of the modern market. In the course of the study, the following methods were used: field, laboratory, and comparative. Determination of the mass, diameter, and sensory assessment of fruits was conducted on 33 varieties of sweet cherries. Experts conducted rating tests on a 9-point scale on ten fruit samples of the examined varieties. Fruits were evaluated by their appearance, aroma, taste, and texture. At the final stage of the assessment, experts calculated the average value of sensory indicators. A sensory profile was set for the fruits of each cherry variety and assigned a score based on the following descriptors: colour intensity, taste, pulp hardness and juiciness, and skin density. The standard methodology for evaluating the sensory properties of fresh fruits has been improved. The average weight (8.41 g) and diameter (22.63 mm) of sweet cherry fruits for three ripening groups were determined. Varieties (Kazka, Dilema, and Udivitiel’na) with the largest mass and diameter of fruits are identified. According to the complex of sensory indicators, the varieties Kazka, Vynka, and Krupnoplidna were distinguished. According to the external attractiveness, consistency, and taste qualities of fruits, a sensory profile has been formed for varieties of different maturation periods. Sensory evaluation of sweet cherry fruits will allow distributing fruit products and selecting raw materials for further use in fresh form, long-term storage, freezing and production of processed products by thermal sterilisation

Recent climate warming is reflected in the advanced onset of spring phenological phases of fruit trees and in so-called false springs. This then manifests as an increased risk of trees being damaged by late frosts in the sensitive growing stage. Based on the homogenised temperature series of 155 climatological stations divided into two altitudinal groups (below 300 m a.s.l. and 301–600 m a.s.l.), a climatological analysis of selected variables in relation to atmospheric circulation over the territory of the Czech Republic during the period 1961–2021 was performed. The number of frost days and the dates of their latest onset exhibited negative linear trends; however, only 16% and 20% were statistically significant. The onset of false spring (at least ten consecutive days with daily maximum ≥ 10 °C) was also characterised by decreasing trends, which significantly deepened after 1980. Spring frost days were particularly attributed to higher frequencies of anticyclonic circulation types such as the central anticyclone and circulation types with northeastern, eastern and southeastern airflow. False spring onset was particularly connected with the central anticyclone and circulation types with western and southwestern airflow. The increasing trends of frost risk days (days between the beginning of the false spring and the date of the latest frost with daily minimum < −1.5 °C) were statistically nonsignificant. Local series of fruit trees from southeastern Moravia proved to have significantly earlier onset of the first blossom and full blossoming phenophases. Although the damage by late frosts has been identified as an important factor contributing to low yields of fruit trees during the period 1996–2021 in the Czech Republic, other factors (e.g. other weather phenomena, diseases, pests, site, taking preventive measures against frost) must also be taken into account.
