Abstract
Rose bushes (Rosa indica 'Sonia', syn. 'Sweet Promise') were grown at controlled root temperatures in an unheated glasshouse. Plant growth, shoot width, number of leaves and breaks per branch, and number and quality of flowers responded to root heating, with an optimum curve which peaked at about 21°C. At a root temperature of 20°C, there was no significant difference in yield and quality of flowers between rose bushes in the unheated glasshouse and those in a commercial, air-heated glasshouse.
