Average three-year results of evaluation of the effect of pruning on morphometric indicators of fruits and kernel suggest the existence of very important differences in treatments in hazelnut cvs Istrian Long, Roman and Tonda Gentile delle Langhe. Fruit shape index as well as kernel shape index have not presented any variations in either of the cultivars, althout changes in the values of the indices have occurred. Fruit volume in pruned bushes of hazelnut cultivars is 10.03-18.46% higher than fruit weight in the unpruned ones. Kernel weight is in correlation with the fruit weight. In all three cultivars the unpruned bushes gave fruits with higher percentage of kernel compared to the pruned ones, difference ranging from 1.46-4.88%. Significant differences are displayes in respect of fruit volume by treatments, and the ratios are as follows: 5.02 : 4.35 cubic cm, 4.91 : 4.31 cubic cm, and 3.52 : 3.15 cubic cm. Number of fruits per kilogram ranges from 240 in pruned to 360 in unpruned bushes. Share of branchlets with greater number of fruits in pruned bushes increases along with their share in total yield.
