ABSTRACT:

Rootstocks are widely used in viticulture due to their resistance to biotic and abiotic stress. Additionally, rootstocks can affect vine growth and fruit quality. This study evaluated the compatibility and initial developmental of the ‘BRS Magna’ grafted on different rootstocks The wedge graft technique on woody cuttings was utilized. The percentage of survival ranged from 0% (‘VR043-43’) to 98.33% (‘101-14 MGT’), and the rootstock were grouped into three distinct groups. ‘IAC 313 Tropical’ and ‘SO4’ rootstocks were those ones with the highest vigor in relation to initial shoot growth. However, ‘IAC 572 Jales’, ‘Harmony’, ‘3309 Couderc’ and ‘Gravesac’ had the best balance between initial shoot growth and root development. The ‘BRS Magna’ when grafted on rootstocks ‘IAC 313 Tropical’, ‘SO4’ and ‘101-14 MGT’ showed the highest initial development rates, while when grafted on ‘R99’, ‘R110’ and ‘420A’, it showed the lowest initial development.

Key words:
Vitis sp.; seedling production; grafting.
