ABSTRACT
In an experimental orchard established in the spring of 2009 at UASVM Bucharest the researches were focused on the assessment of morpho-productive capacity of some new modern sweet cherry varieties grafted on different rootstocks in the first years after planting. Ten cultivar/rootstock combinations were evaluated: Kordia/Colt, Kordia/PHLC, Ferrovia/Colt, Ferrovia/PHLC, Skeena/Colt, Skeena/PHLC, Van/PHLC, FirmRed/CAB6P, GiantRed/CAB6P, EarlyRed/CAB11E. Trees are planted in a high density plot (4x1,5m) trained as central leader and drapeau with a trellis system and drip irrigation provided. Biometrical and phonological dates were collected. In terms of growth vigor, the most vigorous combination expressed as TCSA and total length of annual increases was EarlyRed/CAB11E. It was noticed that rootstock PHLC determined the formation of a greater number of medium fruiting branches at Kordia and Ferrovia varieties. GiantRed/CAB6P and EarlyRed/CAB11E had the highest number of flowers/tree but the percentage of fruit set was very weak. The most productive combinations were Van/PHLC and Ferrovia/PHLC but the highest fruits in terms of weight were recorded by FirmRed/CAB6P and GiantRed/CAB6P.
