Flowers of the ‘Sandra’ and ‘Chinera’ cultivars of carnation (Dianthus caryophyllusL.) last about twice as long (14 days) as those of ‘White Sim’ cultivar (7 days). Application of C2H4shortened the vase life of all three cultivars. ‘Chinera’ flowers were the least sensitive to C2H4and ‘Sandra’ flowers were more than 10 times as sensitive. Although ‘Sandra’ flowers normally produced very little C2H4, C2H4treatment induced a climacteric in C2H4production by this cultivar. The differences in C2H4sensitivity could only partly be explained by differences in ethylene-binding activity (number of binding sites andKd) in petal tissues from the different cultivars.
