Résumé

Grevillea 'Sylvia' is a novel cut flower of sub-tropical to tropical origin. Cut inflorescences were dry-stored at 0, 5 or 10 °C for 3, 6, 9 or 12 days. Inflorescences stored at 0 °C for 3 or 6 days maintained a post-storage vase life of 7 days, which was similar to that of non-stored (control) inflorescences. There was no evidence of chilling injury even after 12 days at 0 °C. Stems stored at 5 or 10 °C for periods of 9 or 12 days suffered significant loss in vase life. Respiration rates of inflorescences stored at 0, 5, 10 or 22 °C fell markedly with decreasing temperature. Temperature quotients estimated for 0-5, 5-10 or 10-22 °C intervals were 2.1, 3.8 and 3.4, respectively. Vase lives after 6, 12 or 18 days dry storage were 8, 6 and 4 days, respectively. To simulate non-refrigerated export by aircraft, inflorescences were held wet or dry for 2 days at 22 °C. Vase life of stored inflorescences was shortened by 1 day compared to non-stored control inflorescences.
