The influence of rootstocks on the sensitivity of flower buds to frost and the main properties of the ‘Carmen’ sweet cherry cultivar

Journal of Agricultural Sciences Belgrade (2021)

Boban Djordjević Dejan Djurović G. Zec Đorđe Boškov

The study examined the influence of five vegetative rootstocks on the flower bud sensitivity to frost during the period of ecological dormancy and the most important biological and pomological properties of the ?Carmen? sweet cherry cultivar. The ?Carmen? cultivar was grafted on the following rootstocks: ?Colt?, ?Gisela 5?, ?Gisela 6?, ?MaxMa 14? and ?Oblacinska cherry?. Winter frosts occurred during the ecological dormancy of sweet cherry trees. The intensity of frost was between -5?C and -7?C. The percentage of damaged and non-damaged flower buds per fruiting branch was determined by counting (50 flower buds per tree were taken from every part of the canopy and fruiting branches). The highest rate of damage of flower buds was in trees grafted on ?Oblacinska cherry?, an average of 77.2% of flower buds, while the lowest was observed in trees grafted on ?MaxMa 14?, an average of 24.3% of total flower buds. The significantly higher sensitivity of flower buds was found in spur fruiting branches compared to lateral fruiting branches. The fruits of the ?Carmen? cultivar had the earliest ripening on rootstocks ?Gisela 5? and ?Oblacinska cherry?. The ?Carmen? cultivar had the highest yield per tree on the ?MaxMa 14? rootstock, while the lowest yield rate was observed in ?Oblacinska cherry?, 5.4 kg and 1.9 kg, respectively. The highest mass of fruits was noticed in trees grafted on ?Gisela 6?, an average of 11.6 g, while the smallest was recorded in trees grafted on ?Gisela 5?- an average of 9.4 g.

Evaluation of cultivars of the European plum ( Prunus domestica L.) from the aspect of conservation and breeding

New Zealand Journal of Crop and Horticultural Science (2024)

V. Rakonjac D. Milatović D. Nikolić Đorđe Boškov

The phenotypic variability of 50 European plum (Prunus domestica L.) cultivars from the germplasm collection of the Faculty of Agriculture in Belgrade was evaluated on the basis of 7 qualitative and 24 quantitative traits over three years. A great diversity between cultivars was found for all analysed traits. The results show that qualitative traits play an important role in the identification of cultivars, as each cultivar has a unique combination of scores. Among the quantitative traits, the greatest variation was found in yield efficiency (0.027–0.757 kg cm−2; CV = 67.0%), yield (4.4–35.7 kg tree−1; CV = 45.6%), maturity index (9.4–42.9; CV = 36.1%), titratable acidity (5.2–17.2 g l−1; CV = 29.4%) and fruit weight (16.5–73.7 g; CV = 29.6%). Principal component analysis (PCA) revealed that the traits related to ripening time, fruit weight, quality and yield accounted for most of the observed variability. Cluster analysis (CA) grouped the analysed cultivars into two main clusters with several subclusters. The results of the present work provide important information on how to best utilise these plum cultivars and can help breeders to select the most diverse cultivars with the best fruit and yield characteristics to be crossed in future breeding programmes.

The Phenolic Profile of Sweet Cherry Fruits Influenced by Cultivar/Rootstock Combination

Plants (2022)

Đorđe Boškov D. Milatović V. Rakonjac G. Zec M. Hudina

The influence of three cultivars (‘Carmen’, ‘Kordia’ and ‘Regina’) grafted on six rootstocks (Mahaleb, ‘Colt’, ‘Oblacinska’, ‘M × M 14′, ‘Gisela 5′ and ‘Gisela 6′) on the phenolic profile of sweet cherry fruits was studied during a two-year period. All the individual phenolic compounds were detected using high-pressure liquid chromatography with diode-array detection coupled with mass spectrometry (HPLC-DAD-MSn). In all the examined samples, 54 compounds were identified and divided into five phenolic classes: anthocyanins (4 compounds), flavonols (7), flavanols (11), flavanones (4), and hydroxycinnamic acids (28). Anthocyanins (58%) and hydroxycinnamic acids (31%) showed the greatest amounts in all the examined fruit samples. PCA analysis revealed that among the cultivars, ‘Kordia’ showed the highest phenolic content. Regarding rootstocks, the lowest values of the most important phenolic compounds were obtained in fruits from trees grafted onto the seedling rootstock Mahaleb. Among the clonal rootstocks, the vigorous ‘Colt’ and dwarf ‘Gisela 5′ promoted the highest values of the evaluated phenolic compounds in the cultivars ‘Kordia’ and ‘Carmen’, while the dwarf ‘Oblacinska’ and semi-vigorous ‘M × M 14′ induced the highest values in the cultivar ‘Regina’. By evaluating the influence of cultivars and rootstocks on the phenolic content in fruit, it has been proven that the cultivar has the most significant influence. However, the rootstock also influences the content of a large number of phenolic compounds. The selection of an adequate cultivar/rootstock combination can also be a powerful tool for improving the phenolic content in fruits, and consequently the nutritional value of sweet cherry fruits.

Fenologija cvatnje i pomološka svojstva sorti badema na području Beograda

Pomologia Croatica (2018)

D. Milatović G. Zec Dejan Đurović Đorđe Boškov

U radu su prikazani fenologija cvatnje i pomološka svojstva sedam sorti badema Prunus dulcis; (‘Exinograd’, ‘Icar’, ‘Mari de Stepa’, ‘Nessebar’, ‘Miagkoskorlupniy’, ‘Prianiy’ i ‘Retsou’) na području Beograda. Ispitivana je fenofaza cvatnje (početak, puna cvatnja, kraj, trajanje i obilnost) kao i svojstva ploda (masa i dimenzije ploda, debljina ljuske, masa i randman jezgre, sadržaj ulja i mineralnih tvari). Prosječno vrijeme cvatnje ispitivanih sorti je bilo u drugoj polovini ožujka i početkom travnja. Cvatnja je počinjala najranije kod sorti ‘Exinograd’ i ‘Nessebar’ (14. ožujka), a najkasnije kod sorte ‘Mari de Stepa’ (1. travnja). Prosječno trajanje cvatnje je variralo od 11 do 22 dana i bilo je duže kod sorti koje su ranije cvjetale. Sorte ‘Icar’ i ‘Exinograd’ su imale krupan plod (s masom iznad 5 g), ali i najniži randman jezgre (ispod 30%). S druge strane, sitan plod (ispod 2,5 g) su imale sorte ‘Retsou’, ‘Miagkoskorlupniy’, ‘Nessebar’ i ‘Prianiy’, koje su ujedno imale i najviši randman jezgre (47-52%). Sadržaj ulja u jezgri je varirao u intervalu od 49% (‘Miagkoskorlupniy’) do 60% (‘Mari de Stepa’). Sadržaj ukupnih mineralnih tvari je iznosio 3,03-3,31%.

The influence of four rootstocks on the growth, yield and fruit quality of two plum cultivars

Acta Scientiarum Polonorum Hortorum Cultus (2022)

Mirjana Radović D. Milatović Gordan N. Zec Đorđe Boškov

The influence of three clonal rootstocks (‘Pixyʼ, ‘Fereleyʼ and ‘St. Julien Aʼ) along with seedlings of Myrobalan(control) on growth, yield and fruit quality of plum cultivars ‘Čačanska Najboljaʼ and ‘Čačanska Lepoticaʼ was studied in the Belgrade region (Serbia) for the six year-period (2013–2018). In comparison to control, clonal rootstocks have shown a significant effect on the decrease of trunk cross-sectional area. The lowest vigor was found in trees on the ‘Pixyʼ rootstock, then on ‘Fereleyʼ and ‘St. Julien Aʼ. Yield per hectare on trees grafted on clonal rootstocks was higher for 62–82% in ‘Čačanska Najboljaʼ, and for 26–27% in ‘Čačanska Lepoticaʼ compared to Myrobalan. In cultivar ‘Čačanska Najboljaʼ significantly higher fruit weight compared to control was obtained in the trees on the ‘Fereleyʼ and ‘St. Julien Aʼ rootstocks. The effects of rootstocks on the contents of soluble solids and total acids in the fruit were not significant. All three studied clonal rootstocks showed better results than standard Myrobalan, and can be recommended for establishing intensive plum plantations with higher planting density.
