Cuttings of Hibiscus rosa-sinensis L. cv. Moesiana were stored at 15 or 760 mmHg (2 or 101.3 kPa) for 3, 5, 8 or 11 weeks. No ethylene production could be detected regardless of treatment. No chlorophyll degradation, proline accumulation or respiratory increase were seen during storage. Stomata were open under low pressure and closed under normal pressure. The open stomata caused water loss from cuttings after removal from storage because they were unable to respond normally to low humidity. Rooting ability decreased as storage time increased, but satisfactory results were obtained up to a storage period of five weeks.
