The promotion of a cherry assortment with constant yield, low vigour of the trees, self-fertility and high productivity, resistance to biotic and abiotic factors and with ripening at the extremities of the cherries maturation season, represents a permanent concern of researchers. In this context, considering the current patrimonial situation and the perspectives of growing sweet cherry trees in the Iasi area, under a privatized agriculture, the selection of new cultivars to be introduced in the assortment requires a special attention. Analyzing the values of the fertility index during the three years of study (2018 – 2020) it was observed that all the cherry cultivars excepting ‘Kordia’ are highly fertility with values between 30.0% and 66.2%. The cultivars ‘Bucium’, ‘Croma’, ‘Van’, ‘Maria’, ‘Stella’, ‘Cătălina’, ‘Margonia’ and ‘George’ have large fruits (over 7 g and over 22.5 mm) and ‘Kordia’ (6.3 g and 21.1 mm), ‘Scorospelka’ (6.2 g and 22.3 mm), ‘Cetăţuia’ (6.0 g and 22.0 mm) and ‘Rivan’ (5.9 g and 21.6 mm) have small fruits. For ‘Scorospelka’, ‘Cetăţuia’ and ‘Rivan’, the fruits are large in comparison with other early cultivars. The values of soluble dry substance (SDS) varied between 13.6% (‘Scorospelka’ and ‘Rivan’) and 18.9% (‘Maria’). However, statistically, cultivars ‘Maria’ (18.9%), ‘Bucium’ (18.3%) and ‘George’ (18.1%) recorded superior values in comparison with all the other cultivars.

AbstractThe aim of this paper is to improve the autochthonous sweet cherry assortment with new cultivars of good adaptability and ecological plasticity, with superior biological potential, productive, with quality fruits and superior features, in comparison to existing cultivars. Due to the characteristic of having an earlier ripening age for the fruits compared to the other tree species (beginning in May), the cherry is the first ring in the annual chain of fruits production. On the fresh fruits market, the preferred ones are the cultivars type ‘bigarreau’, with shining red colour, resistant to cracking, transport and temporary storage with the weight of over 7 g. Analysing the main phenological stages for the two cultivars, it was noticed that the new sweet cherry cultivar ‘Elaiaşi’ is average both in flowering beginning time and fruits maturation season. In regards to average productions for five years (2012 - 2016), from the statistical point of view, it was noticed that ‘Elaiaşi’ (21.1 kg/tree) recorded production with insignificant positive differences in comparison to the witness cultivar ‘Van’ (20.2 kg/tree). Under the aspect of fruits’ weight and equatorial diameter, ‘Elaiaşi’ (8.8 g and, respectively, 25.1 mm) recorded significant and respectively positive significant differences, in comparison to the witness cultivar ‘Van’ (7.6 g and 23.9 mm). Concerning the fruit’s resistance to cracking, ‘Elaiaşi’ cultivar presented a superior resistance (2.7 %) to the witness cultivar ‘Van’ (42.0 %), recording distinct significant negative differences in comparison to this cultivar from the statistical point of view.

The tensile strengths of graftings between three selected sweet cherry cultivars and five selected cherry rootstocks were determined with an Instron instrument 6, 12, and 18 weeks after grafting and compared with the tensile strength of self-grafted rootstocks and graftings of rootstocks used as scions. The combination of sweet cherry cultivars and rootstocks was selected to provide a range of compatibility based on preliminary work. The tensile strengths of sweet cherry cultivars grafted on different rootstocks never exceeded the tensile strengths of the self-grafted rootstocks. Rootstocks grafted as scions on Prunus avium L. rootstocks and self-grafted rootstocks produced some of the strongest unions tested and also produced union strength much faster than any of the other combinations. The degree of compatibility was quantified and results indicated that if this value was below 0.2, measured 18 weeks after grafting, it corresponded to combinations with major risks of delayed incompatibility.Key words: tensile strength, grafting, compatibility, sweet cherry, Prunus avium.

Selection Of

The goal of this investigation was to determine genetic differences between autochthonous and introduced cultivars of sweet cherry and between cultivars and types of sour cherry, and to find and optimize a method for the rapid recovery of clonal material. A great number of cherry cultivars and types within the population of cv. Oblačinska sour cherry exist in Croatia and the selection of autochthonous cultivars based on special visible properties for further investigation has been done in previous research. Differences were found in a number of important agronomic traits within the populations of cv. Oblacinska sour cherry. It is suspected that autochthonous sweet cherry cultivars are synonyms for known old cultivars, which were introduced randomly and naturalized under local names. In this approach difficulties arise from the effect of non-genetic factors on the expression of certain traits. The genetic/physiological problem of S allele autoincompatibility exists within sweet cherry cultivars. The detection of S alleles is required to determine compatible cultivar pairs in the orchard. Biotechnological methods based on the polymerase chain reaction (PCR) facilitate faster virus detection compared with classical serological methods and indexing. Thermotherapy and tissue culture make it possible to recover valuable clone material for introduction in the premultiplication process.

AbstractThe study was performed at the Experimental Station of Agriculture - Khan Krum in the period 2018-2019. The experimental plantation was established in 2001, the early Bigareau Burlat, middle early Bing and the late Germersdorfer and Van were tested. The planting material was produced on a mahaleb rootstock. The distance of planting was 6 meters interrow spacing and 5 meters intrarow spacing. The experiment was based on three replications each of them reported on a separate tree. When analyzing the frost percentage of flowers, 400 blossoms were taken from three levels of the crown of each tree, the same number of fruits were taken to determine the cracking percentage. Percentage of damaged blossoms, yield kg/ha and percentage of fruit cracking as a result of fallen rains during harvest were established. The purpose of the study is to investigate the influence of abiotic factors on the yield and quality of four sweet cherry cultivars. In this regard, the frost percentage in the range of values was 67,3 - 100%. Bigareau Burlat yield was not obtained, and it was relatively low from Germersdorf and Bing (20,1 - 24,6 kg/ha) at Van 84,6 kg/ha. The number of cracked fruits due to fallen rains during harvest was relatively high in Van and Bing (39,8 - 47,4%), while in the Germersdorf cultivar it was lower - 21,2%.

Abstract The studies were performed for four consecutive years (2016–2019) at the Fruit Growing Research Station (North-East part of Romania), using eleven sweet cherry genotypes as research material. Five of them are new cherry cultivars – ‘Cătălina’, ‘Andreiaş’, ‘Maria’, ‘George’, and ‘Margonia’ – obtained by means of controlled hybridization or open pollination, and six of them are their progenitors (‘Van’, ‘Boambe de Cotnari’, ‘Stella’, ‘Fromm’, ‘Ciliegia di Ottobre’, and the ‘HC 27/4’ hybrid). The experiment compared the traits of new cultivars with those of their progenitors. The following traits were evaluated: tree vigor, frost damage, the phenological stages, and the physical and chemical traits of the fruit. The highest values concerning the fruit's weight have been recorded for ‘Andreiaş’ (10.0 g) and ‘Maria’ (7.6 g), the content of soluble substance was between 16.6 and 19.5°Brix, the titratable acidity was between 0.413 and 0.675 mg malic acid·100 mL−1 juice, and the total content of polyphenols was recorded with values between 268.00 and 488.75 mg GAE·100 mL−1 of fresh juice. The new cultivars have mostly superior traits, especially frost damages, productivity, fruit quality, and fruit's cracking percentage compared with their parental genotypes.

Quality Measurements

Several sweet cherry (Prunus avium L.) cultivars were stored in air or modified-atmosphere packages (MAP) at 1 °C for 2 or 4 weeks, respectively. The new cultivars included `Santina', `Sumpaca Celeste', `Sumnue Cristalina', `Sumste Samba', `Sandra Rose', `Sumleta Sonata', and `Skeena', and the standards were `Lapins', `Sweetheart', and `Bing'. Fruit were rated for defects (stem browning, stem shrivel and fruit surface pitting), and fruit quality at harvest and after storage. Weight loss during storage was influenced by year, storage treatment, and cultivar. Stem shrivel, stem browning, and fruit surface pitting varied among cultivars and years. Generally, fruit stored in MAP had higher fruit firmness than at harvest or when stored in air. The respiration rate of fruit was lower in later than in earlier maturing cultivars, but respiration rate at harvest was not related to any of the quality measurements taken after storage.

Sweet cherries (Prunus avium L.) are highly appreciated fruits for their taste, color, nutritional value, and beneficial health effects. In this work, seven new cultivars of sweet cherry were investigated for their main quality traits and nutraceutical value. The phytochemical profile of three classes of phenolic compounds and the antioxidant activity of the new cultivars were investigated through high-performance liquid chromatography with diode array detection (HPLC-DAD) and spectrophotometric assays, respectively, and compared with those of commonly commercialized cultivars. Cyanidine-3-O-rutinoside was the main anthocyanin in all genotypes, and its levels in some new cultivars were about three-fold higher than in commercial ones. The ORAC-assayed antioxidant capacity was positively correlated with the total anthocyanin index. The nutraceutical value of the new cultivars was investigated in terms of antioxidant/neuroprotective capacity in neuron-like SH-SY5Y cells. Results demonstrated that the new cultivars were more effective in counteracting oxidative stress and were also able to upregulate brain-derived neurotrophic factor (BDNF), a pro-survival neurotrophin, suggesting their potential pleiotropic role in counteracting neurodegenerations.

Abstract The paper proposes the improvement of the current bitter cherry assortment with new creations made at Iaşi, adapted to the specific conditions from the NE area of Romania. For the improvement of the bitter cherry assortment with new, productive, disease resistant cultivars with fruits of good quality, resistant to cracking with different maturation stages, in 1981 at Fruit Growing Research Station (F.G.R.S.) Iaşi - Romania has begun an action of selection and promoting of some valuable genotypes of bitter cherry (existent in the spontaneous flora or in plantations from the Iaşi county), which were being planted with cultivars and other genotypes from all around the country. Following the positive and gradual selection there were selected three biotypes of bitter cherry from which two of them have been approved as new cultivars in 1994, with the names „Amar Maxut”, respectively, „Amar Galata” and the biotype „Amar R5.P10” has been registered in 2013 at the State Institute for Variety Testing and Registration Bucharest to be approved as a new cultivar. All three bitter cherry genotypes correspond to the objectives of the main assortment breeding. They have a high productivity because the natural fertility index registered values between 36.5-63.7%, the trees have a reduced vigour, they present a good resistance to frost (1-9% affected buds) and to diseases (values of I% anthracnose, 1.1-2.8%). The fruits are high quality and the maturation stages are at the extremities of the cherries maturation season.

There are several extended studies in sweet cherry production in Hungary and all over the world i.e. for creation and maintainence of smaller tree crown and high density orchards. The use of suitable dwarf rootstocks for this fruit species are very limited. On one hand, most of the draf rootstocks do not cause enough growth reduction and on the other hand these rootstocks are get old very quikcly and their fruits become small, and therefore, they not serve the requirements for intensification. In summary, there is a need for those rootstock which are vital, regeneration enhanching and delay ageing. Due to ensuring above features, Prunus mahaleb is still an obvious solution for intesive production. Increasing intensification can be obtained by use of modernisation of technological elements and suitable cultivar choice. According to this increasement of intensity through application of novel technological elements (timing, manner and severity of pruning) and selection of the proper cultivar is implement able. Important differences are experienced between sweet cherry cultivars in their growth attributes, light demand and dynamics of fall back in regenerative potencial of different aged wood parts. From this point knowledge of the abow detailed is very important in order to maintain rentability of already established plantations. Our work shows the formation of production part in9-year old plantation with spike spindle and free spindle crown forms depending on pruning timing (winter, summer) and determining of their various effects.
