The possibility of vary simple genetic control mechanism or of a threshold effect were raised. However, significant
differences among clones within the compatibility status groups suggested that other factors probably
are involved [14]. The relationship among measured factors in the present study indicated that interaction of
scion and rootstock was significant; incompatibility signs did not seen even one year after grafting but Dolcevita
on R. manetti had highest healing percentage (78.49%) and Avalanch on R. manetti had lowest healing percentage
(46.13%), (Table 2). Result of interaction between time of propagation and type of cultivar showed T2R2S3
had more healing percentage (Figure 1). According to the result of analysis of data (Table 1), the highest number
of root was obtained in late of September.
