In 1999–2001 years on rootstocks of I, II, III quality of Rosa multiflora Thunb., thornless, the buds of two cultivars (Friesia and Nina Weibull) from the floribundas group were budded from different thickness scions. The dominant influence of quality of the rootstock on budding results of studied rose cultivars from the floribundas group was ascertained, however the quality of the scions didn’ t matter. The planted rootstocks of I quality rooted very well every three vegetations seasons. In years 2000 and 2001, when the amount of rainfall during the first three months after planting was small, the rootstocks of II quality and particularly the ones of III quality, rooted in lower percentage than the rootstocks of I quality. During budding time the III quality rootstocks had thinner neck root in comparison to rootstocks I and II quality. Yet the rooted III quality rootstocks were budded in nearly 100%. The buds of roses of both cultivars on the III quality rootstocks overwintered in lower percentage than the ones budded on the I and II quality rootstocks. There was no significant influence ascertained in kind of quality of rootstock and of scion
on number of I order shoots that grew in springtime from buds and on number broken off shrubs.
