The studies conducted in the years 2004–2006 in a production orchard in the habitat conditions of the Sandomierska Upland showed that the trees budded on the seedlings of wild cherry grew more strongly than on Colt rootstock. No significant differences were observed between the rootstocks as for the trunk thickness and the crown size of young trees planted in 2001. In the group of trees planted in 1996, which were in the period of full fruiting, the crowns of trees budded on wild cherry were significantly bigger than on Colt rootstock. No significant differences were found out in the yielding of trees on wild cherry and Colt rootstock. Considerable differences in the yielding between the studied years in the group of young trees with systematic increasion was effected by increase of crown. ‘Kordia’ cv. is a valuable cultivar for Sandomierska Upland. It begins late the fruiting period (the first commercial yield in the fifth year after planting); however, it gives attractive fruits and high productivity of trees.

The subjects of this study were 8-year-old sweet cherry trees of the cultivar 'Kordia' grafted on the 'Colt' rootstock. The trees had been trained as spindles for four years after planting. In the fifth year, four systems of pruning were introduced: 1) the spindle form - i.e. the pruning system remained unchanged, 2) Zahn's method of pruning, 3) one-year-old shoots were cut back leaving approximately 10 buds, 4) no pruning at all - control trees. An assessment of the effects of these training systems was carried out in the third and fourth year of the study. The best results were obtained with the trees formed in the shape of a spindle and the trees pruned according to Zahn's recommendations. Cutting back long one-year-old shoots caused a significant decrease in the total yield and a small increase in the average fruit weight. The smallest values of canopy volume were obtained in the combination where long shoots had been shortened, while the largest canopies were found in the control combination. Canopy volumes of the trees shaped as spindles and of those pruned using Zahn's method were similar.

The experiment was set up at the Experimental Orchard in D ^browice, Poland in the spring of 2005. The experimental plant material consisted of sweet cherry trees cv. 'Kordia' planted in three rootstock and two interstem combinations. The rootstocks included 'Gisela5', 'F12/1' and 'Colt'. The interstems were 20 cm long shoots of 'Gisela 5' grafted on 'F12/1' or 'Colt' rootstocks. All the trees were planted at the same spacing of 4.5 x 2.5 m in a random block design, in four replicates with three trees per plot. The tree training method was the Vogel Central Leader. In the fifth year of the experiment, the sweet cherry trees growing in the combinations with the rootstocks 'F12/1' and 'Colt' showed the strongest growth, The combinations with 'Gisela 5' dwarfing rootstock grew least vigorously. In the 2009 season, the 'Kordia' trees produced fruit yields at a very good level. The trees with 'Gisela 5' interstems grafted on the rootstock 'Colt' produced the highest yields (more than 30 kg per tree). Five years after being planted, 'Kordia' trees with 'Gisela 5' interstem grafted on 'F12/1' rootstock had the highest cumulative yield. Trees with 'Gisela 5' interstems grafted on the 'Colt' rootstock and those grafted directly on the 'Colt' rootstock produced similar yields. Trees grafted directly on the 'Gisela 5' rootstock had the lowest yields.

In the field experiment, 11-year-old 'Kordia' sweet cherry trees grafted on 'GiSelA 5', 'P-HL A', 'P-HL B', 'P-HL C', 'Maxma Delbard 14 Brokforest', 'Wei- root 158' and 'Tabel Edabriz' semi-dwarfing and dwarfing rootstocks were compared with trees of the same cultivar on the standard rootstock 'F 12/1'. The results revealed that all semi-dwarfing and dwarfing rootstocks tested (with the exception of 'Maxma 14'), in comparison to the standard rootstock 'F 12/1', significantly reduced the growth of 'Kordia' sweet cherry trees. The most dwarfing root- stock was 'Tabel Edabriz', followed closely by 'GiSelA 5', 'P-HL A' and 'P-HL C'. The highest cumulative yields were harvested from trees grafted on 'GiSelA 5', 'Maxma 14' and 'P-HL B'. Rootstocks with the highest yield efficiencies were 'GiSelA 5' and 'Tabel Edabriz'. The lowest yield efficiency in this study was recorded for trees on 'F 12/1'. Trees grafted on 'Tabel Edabriz' produced smaller fruits than those grafted on other rootstocks tested. In this trial, the concentration of soluble solids in fruits of 'Kordia' sweet cherry trees grafted on 'F 12/1' and 'Maxma 14' vigorous rootstocks, was significantly lower than in fruits harvested from trees grafted on dwarfing or semi dwarfing rootstocks.

The study involving 5 cherry cultivars was conducted in 2015–2016. The varieties ‘Techlovan’, ‘Summit’, ‘Sylvia’, ‘Kordia’ and ‘Regina’ were planted in 2010 in the Experimental Orchard of the Department of Pomology in Warsaw-Wilanów on GiSelA5 rootstock. The aim of the study was to evaluate the production value and dessert fruit quality as well as health proprieties of the tested cultivars’ fruits and select the most valuable ones. It was shown that the varieties differed in fruit set and yielding as well as fruit quality (i.e. fruit size, firmness, soluble solid content, acidity) and health benefits (i.e. polyphenol, anthocyanin, and ascorbic acid content). ‘Techlovan’ trees had the lowest yield, but their fruits were of high quality. ‘Kordia’ and ‘Regina’ also provided high quality fruit with high total polyphenol content. In contrast, the ‘Sylvia’ cultivar had a high yield, but the fruit obtained from it was of poor quality. All tested cultivars had similar vitamin C content.

Celem przeprowadzonych badań była ocena wzrostu i plonowania drzew czterech odmian czereśni okulizowanych na dwóch podkładkach. Badania przeprowadzono w latach 2011-2013 w sadzie produkcyjnym zlokalizowanym na terenie Wyżyny Sandomierskiej. Materiał doświadczalny obejmował czereśnie odmian: ‘Kordia’, ‘Regina’, ‘Summit’ i ‘Vanda’ w wieku od 3 do 5 lat, okulizowane na podkładkach: GiSelA 5 i Colt. Wzrost drzew czterech odmian czereśni określony powierzchnią przekroju poprzecznego pni, objętością korony, współczynnikiem intensywności owocowania i produktywności korony istotnie zależał od odmiany i typu zastosowanej podkładki. Drzewa odmiany ‘Summit’ średnio za cały cykl badań plonowały istotnie najlepiej, zaś ‘Kordia’ i ‘Vanda’ istotnie najsłabiej. Drzewa uszlachetniane na podkładce GiSelA 5 charakteryzowały się istotnie mniejszą powierzchnią przekroju poprzecznego pni i objętością korony oraz istotnie większym współczynnikiem intensywności owocowania, produktywności korony oraz średnim plonem za cały cykl badań niż drzewa na podkładce Colt. Istotnie największą masą owocu czereśni i pestek charakteryzowała się odmiana ‘Regina’. Owoce odmian ‘Kordia’ i ‘Regina’ zawierały istotnie więcej ekstraktu niż owoce pozostałych odmian. Nie wykazano istotnego wpływu typu podkładki na masę owocu i pestki, procentowy udział pestki w owocu oraz poziom ekstraktu.

During the cold storage of sweet cherry, severe losses can occur due to the water loss, phytopathogenic fungi and physiological disorders. The aim of this research was to assess the effects of treatments with NAA (α-naphthaleneacetic acid), BA (6-benzyladenine), and GA3 (gibberellic acid) on fruit quality at harvest and after 21 days of storage under two regimes, including 0°C, RH (relative humidity) 90% and 3°C, RH 70%, and after additional shelf life exposure. Sweet cherry cultivars – ‘Summit’, ‘Kordia’ and ‘Regina’ – were treated with bioregulators at the end of flowering. NAA significantly increased the fruit weight at harvest compared to the control in all cultivars assessed. BA stimulated the fruit growth in ‘Kordia’ and ‘Regina’, while it was ineffective in ‘Summit’. GA3 caused significant increase in fruit weight by 8.3% in ‘Kordia’ only. Moreover, BA and GA3 induced a higher firmness of fruits at harvest. Weight loss of fruits during storage at 0°C, RH 90%, was increased with NAA and reduced with GA3 in ‘Regina’ only. BA and GA3 reduced the weight loss of sweet cherry fruits stored at 3°C, RH 70%. Bioregulator treatments increased TA (titratable acidity) in fruits at harvest, while the effects on TA during storage were variable depending on the cultivar. ‘Summit’ had the highest sensitivity to storage fruit rot. BA and GA3 decreased the disease occurrence on fruits stored at 0°C in ‘Summit’ and ‘Kordia’.
