The experiment was conducted in 2006-2008 in the Didactic and Experimental Garden of the University of Warmia and Mazury in Olsztyn, Poland. The research materials were sour cherry trees of the 'Kelleris 16', 'Ujfehertoi Furtos' and 'English Morello' cultivars, grafted on rootstock of Mahaleb seedling, Mazzard seedling and F12/1. The 'English Morello' cultivar grafted on the rootstock of Mahaleb seedling demonstrated the highest productivity. The same cultivar grafted on the rootstock of Mazzard seedling and Fl2/1, along with the 'Ujfehertoi Furtos' cultivar on Mahaleb seedling and Mazzard seedling, had the lowest productivity. The largest sour cherry fruits were recorded for the 'Ujfehertoi Furtos' cultivar. From all the cultivars examined, Mazzard seedling rootstock resulted in the largest fruit weight. A fruit quality evaluation based on their chemical composition revealed the highest content of ascorbic acid in fruits of the 'English Morello' grafted on F12/1, and the lowest value was recorded for the 'Ujfehertoi Furtos' on Mahaleb seedling. The highest sugar content was found in fruits of the 'Ujfehertoi Furtos'. Mahaleb seedling in all cultivars under examination had a favourable effect on sugar accumulation in fruits. Fruits of the 'Ujfehertoi Furtos' cultivar grafted on the Mahaleb seedling contained the highest amount of organic acids, while 'Kelleris 16' on the same rootstock and 'English Morello' on F12/1 had the lowest.

The experiments were carried out in 2005-2007. The aim of the study was the evaluation of the growth and yielding of sour cherry cultivars in central Poland. The explored cultivars differed in vigour, cropping and also in response to spring frost. The most vigorous, indicated by the trunk cross-sectional area (TCSA), length of one-year shoots and leaf area, were 'Sabina', 'Lucyna', 'Karneol' and 'Ujfehertoi Furtos'. The weakest in vigour were 'Northstar', 'Schattenmorelle IR-2' and 'Koral'. The best fruit set was observed in 'Schattenmorelle IR-2' and the worst in 'Karneol'. The cultivars 'Lucyna', 'Schattenmorelle IR-2', 'Sabina' and 'Vowi' gave the highest yield per tree. 'Karneol', 'Ujfehertoi Furtos', 'Northstar' and 'Debreceni Botermo' gave the lowest yield per tree. The greatest damage by the spring frosts of 2007 was observed in the following cultivars: 'Lucyna', 'Debreceni Botermo', 'Karneol' and 'Sabina'. The most resistant to spring frosts turned out to be 'Northstar' and 'Schattenmorelle IR-2'.
