The infl uence of the rootstocks МАС 9, М 9, М 26 and ММ 106 upon the temperate growing cultivar Golden Resistant was studied over three years. The rootstock МАС 9 induced the lowest tree sizes, while ММ 106 induced the largest sizes. The decreasing effect of МАС 9 is expressed also in the lowest total growth during the studied period. Regarding the reproductive behaviour totally for this period МАС 9 has formed the signifi cantly highest number of fruit-buds compared to all the rest of the rootstocks.
