Summary

Cut carnations (Dianthus caryophyllus) with two leaves (20 cm in length) were treated with 3 types of preservatives in order to maintain freshness at room temperatures of 14-25 °C and RHs of 69-89%. The best effect was obtained with 50 mg AgNO3 + 40 mg benzoic acid + 200 mg 8-HQ/litre + 3% sucrose. After treatment, the fresh weight and diameter of cut flowers increased, water balance in plants improved, and peroxidase activity was inhibited. This resulted in delayed petal withering (caused by water loss) and greater longevity of cut flowers.
