Abstract. The vegetative manifestations of three cherry clonal rootstocks Merisier F12.1, Saint Lucie GF 64 and Gi-Sel-A 5, grafted with the variety Summit, were studied in nursery. Merisier F12.1 and especially Gi-Sel-A 5 have earlier attenuation in the pace of the rootstocks thickening in the nursery during the I-st year. Under the influence of slowly growing Gi-Sel-A 5 the graft has a lower rate of weight gain and increase in height. Summit/Saint Lucie GF 64 has the greatest length of annual growth.
