摘要：

Cut flowers of the 'Sandra' and 'Chinera' cultivars of carnation (Dianthus caryophyllus L.) lasted about twice as long (approx. 14 days) as those of 'White Sim'. Vase life of 'White Sim' was unaffected by the age of the flower at harvest, but the life of 'Sandra' and 'Chinera' fell as flower age at harvest increased. The senescence of 'White Sim' and 'Chinera' carnations, indicated by petal in-rolling and wilting, was accompanied by a marked increase in respiration, 1-aminocyclopropane-1-carboxylic acid (ACC) content, ethylene-forming enzyme (EFE) activity, and C2H4 production. In contrast, 'Sandra' flowers showed neither petal in-rolling nor climacteric respiration and C2H4 production during their eventual senescence. There was negligible ACC and very low EFE activity in petals of 'Sandra' throughout the post-harvest period.
