In 2 successive years, 11-month-old cut rose clones grown in greenhouses were uprooted in December. Highly significant correlations occurred between the girth at the graft union and the root weight or the number of bottom-breaks, between the root weight and the number of bottom-breaks, and between the number of bottom-breaks and the number of harvested shoots. Plant vigour in clones was mainly determined by the scion. Rootstock-scion relations in rose were similar to those in apples and cherries. The equilibrium between aerial and underground parts in composite plants is discussed. Breeding of rose rootstocks that promote scion vigour under various glasshouse conditions is recommended.
