Health status and longevity of ‘Van’ and ‘Büttners Red’ - two cultivars of sweet cherry trees with different interstocks grafted on Mazzard seedlings were investigated at the Experimental Station in Lipowa (southern Poland). Two sour cherry cultivars - ‘Northstar’ and English cherry from Kent F442, two types of Prunus fruticosa - No 8, syn. ‘Frutana’ and No 9, and Prunus avium F12/1 were used as interstocks. Trees of each cultivar without interstock were used as control. Tree sizes and their health status after 25 years in the orchard were recorded. Interstock modified the tree size and architecture of trunk. The healthiest and mostly productive were tress with ‘Frutana‘ interstock and the worst - with interstock of F12/1 cherry. Remaining interstocks did not have any significant influence on the longevity and health status of trees.
