Abstract
The wine viticultural in Dragasani was founded in 1896 after the attack of the philoxera, being among the first units of producing vine planting material in the country alongside the one in Odobesti.
For the production of vine-growing planting material, a number of intensive methods have been developed, aimed at improving quality, increasing production and lowering the cost of production.
The influence of the rootstock on the graft lies in the supply of substances to the roots, in a higher or lower proportion that can develop or weaken the root system.
This influence is stronger the more affinity there is.
The multiplication of the vine is conditioned by a complex of pedoclimatic, technological and biological factors, which are closely related and act on the growth and development of the vine, especially on calluses.
For the research carried out in 2021-2023, the following grape cultivars of rootstocks were studied: ‘Kober 5BB’, ‘Craciunel 2’, ‘SO4-4’, ‘M70’ grafted with the grape cultivars created at the Research Development Station for Viticulture and Winemaking Dragasani: ‘Crâmpoșie Selecţionată’, ‘Tămâioasă Românească 104 Dg’, ‘Sauvignon 62 Dg’, ‘Novac’, ‘Negru de Drăgășani’, ‘Cabernet Sauvignon cl. 7’, ‘Victoria’, ‘Crâmpoșie Aromată’.
