The aim of this research was to study the influence of some plant growth regulators, as well as some edible colors as a pulsing solution in the postharvest characteristics of Mums cut spike. Five pulsing treatments were used, as two plant growth regulators (GA₃ and Kin) with one fixed concentration for each one (25 and 5 mg/L, respectively) plus two pulsing times (1 and 2 hours) for each, beside the control (distilled water) were applied. Each pulsing treatment was trans-located into nine treatments of the dyeing solutions, since two edible colors {Ponceau 4R (red) and Brilliant blue (blue)} with two concentrations (3 and 6 g/L.) for two dyeing time (2 and 3 hours), plus the control (distilled water). Results indicated that the combinations between GA₃ for 1 or 2h with the two edible dyes increased the vase life and had the upper hand than using kin in most of the cases in that respect. Since, the highest vase life of 26.00 days was recorded eight times, most of them for the superior previous combinations. Also, the combination between GA₃ for 2h and 6 g/L blue dye for 3h was more effective in increasing the change of fresh weight values, comparing with most of the other interaction, especially from the beginning of the experiment till the 8th day. The maximum change of water uptake values (46.49 and 44.85 ml/100 g FW/2day) were recorded for the combinations of GA₃ for 2h + 6 g/L blue dye for 3hours, and kin for 1h + 3 g/L red dye for 3h, respectively. In addition, the combinations between GA₃ pulsing period and the dyeing treatments were more effective in reducing the water loss and increasing water balance comparing with the kin pulsing with the same dyeing treatments in most of the cases. The interactions among the blue dye at 6 g/L for 3h and each of the plant growth regulators type and pulsing time, significantly increased the total chlorophylls content and the total sugar % than all the other interactions.  Finally, the least average of bacterial count obtained by using GA₃ for 2h plus 6 g/L blue dye for 3h when compared with the other treatments.
