Abstract: 
The main objective of the present study was to investigate the effect of plant growth regulators on the prolongation of vase life of two types of cut carnation under normal conditions and ethylene stress. Carnation is one of the most popular flowers with a short life due to its sensitivity to ethylene. The effect of plant growth regulators on several physiological traits under ethylene stress and normal conditions was also studied. The effects of shortterm treatment with benzyl adenine (BA), salicylic acid (SA), and methyl jasmonate (MeJA) were investigated on two types of cut carnations (Dianthus caryophyllus L. ), one-headed standard cut carnation and multi-flower mini cut carnation, under ethylene exposure. The short-term treatment with 100 μ M benzyl adenine had the strongest effect on total chlorophyll content. The treatment with 100 μ M SA enhanced the soluble carbohydrates and prolonged the cut carnation vase life. The plants treated with 400 μ M MeJA showed an elevated level of catalase and peroxidase enzymes activity and an increase in the proline content. All considered traits were reduced by exogenous ethylene. None of the short-term treatments could repel the inappropriate exogenous ethylene effects. One-headed standard carnations were also more ethylene tolerant than multi-flower mini carnations.
