LANDSCAPE ROSE RESPONSE TO LOW MOISTURE LEVELS AND A HYDROPHILIC GEL Academic Article uri icon

abstract

  • Containerized plants of five low-maintenance rose (Rosa hybrida L.) cultivars were irrigated at intervals which limited moisture availability for plant growth and development. The cultivars were grown both in a medium amended with a hydrophilic gel and in a control medium. Of the five cultivars, 'Pink Meidiland' had the highest leaf water potential (L) and lowest transpiration (E), while 'Ferdy' maintained the highest E. The smaller leaf surface area of 'Pink Meidiland' and larger root to shoot ( R S) ratio and lower leaf area ratio (LAR) of 'Ferdy' contributed to a more favorable water status despite limited moisture availability. When hydrophilic gel was utilized as a medium amendment, L was generally higher. Gel had little effect on plant biomass and tended to decrease tissue nutrient content. 1991.
