Impact of orchard management technologies on apple fruit internal quality was tested in several trials performed at the Institute of Horticulture, Lithuanian Research Center for Agriculture and Forestry during 2010-2019. Studies were focused mainly on the research of bioactive compounds: triterpenes and phenols. Studies included rootstocks, crop load regulation, planting distances, fruit position in the tree crown, geographical locations, regulation of tree vegetative growth by root pruning, trunk incision and prohexadione-calcium. ‘Auksis’ apple fruits on P 67 rootstock and ‘Ligol’ on P 61 and P 22 had the highest total phenol content, while the lowest total phenol content of both tested cultivars was recorded on M.9 and P 62 rootstocks. Increasing crop load on the tree led to significant increase of phenols and triterpenes. Higher fruit triterpene concentration was recorded on denser planted trees. Root pruning increased accumulation of phenols, while by the application of prohexadione-calcium the accumulation of phenols decreased significantly. Lower triterpene concentration was recorded when tree growth was controlled by trunk incision. Fruits from the top of the tree accumulated significantly higher amount of phenolic compounds, whereas fruits inside the tree crown were characterized by the highest amount of triterpene compounds. Colder climate during the vegetation and shorter vegetation period resulted in significantly higher accumulation of phenolic and triterpene compounds in apples grown in Estonia comparing to fruits grown in Poland. New scientific results on the impact of modern technologies on the changes of internal fruit quality parameters could increase consumption of apples.

In total 14 cherry cultivars and advanced selections released by the Pacific Agri-Food Research Centre (PARC-Summerland), Agriculture and Agri-Food Canada were tested at NIBIO Ullensvang during 2010-2016. The scions were grafted on the dwarfing Gisela 5 rootstock and planted in high tunnels. Main phenological, vegetative growth and productivity characteristics and fruit quality parameters were evaluated and detailed information about the different cultivars and selections are presented. After comprehensive studies the cultivars ‘SPC 108’ and ‘Starblush’ are recommended for commercial fruit growing in Norway in addition to the main cultivar ‘Lapins’. ‘SPC 107’ is recommended for home gardens. The selection SPC 263 and ‘Sofia’ showed outstanding fruit quality parameters, but had low productivity due to stunted tree growth. Grafting on more vigorous rootstocks than Gisela 5 is recommended.
