ABSTRACT

The research and work was carried out in Syria / Tartous Governorate / Beit Kamouna / (Tartous Agricultural Center) of Tartous Agriculture Directorate located to the south of the city. (2016)
The research aims to test the effect of the date on the degree of compatibility of the first between the rootstocks (peaches, almonds – peaches), which are grafted with a local taste (early Nectarine), the rootstocks of the varieties studied at different dates and commensurate with each of the methods of grafting used are as follows:
A: tongue grafting: First date: 16/1 Second date: 1/2 Third date: 17/2
B: B-Breclad and T budding: First date: 3/3 Second date: 18/3 Third date: 2/4. The success rates on almond origin and the three dates studied were respectively (85%, 90% , 95%)
The highest was the third date where the third date exceeded the second and the second on the first while the results proved that the cultivar (early Nectarine) can be grafted on the roots (peaches, peaches) on the three dates studied and high success rates, respectively for the peach root (90,90) , 90) and on the rootstock of peaches (100,100,100) and the rootstock of peaches outweigh all rootstocks (almonds – peaches) and the three dates studied.

Keywords: peach. Prunus persica, peach varieties, seed roots, grafting, degree of compatibility
