Effects of 1-aminocyclopropane-1-carboxylic acid (ACC; 1 mg L−1) alone and in combination with sodium nitroprusside (ACC; 1 mg L−1 + SNP; 10 mg L−1) on the vase life (a), ethylene production (b), and relative fresh weight (RFW) (c) of cut carnation flowers (‘Tico Viola’) during the vase life period. Data represent mean of three replicates, while bar indicates standard deviation. Means with different letters are significantly different (LSD test, p < 0.05)
