Primula is one of the flowering flowers in the world that to be released market in pots. The flower are very sensitive to ethylene and this makes the marketing process is damaged. In order to improve the effect of 1-MCP on the vase life of primula, a study in a completely randomized design with one concentration factor using of 1-MCP at five levels (0, 50, 100, 150 and 200 Nll-1) in three replications and 18 experimental plots with 5 plants were performed. The results of data analysis indicate that the effect of 1-MCP concentration on the measured traits of chlorophyll a were statistically significant at level of 1. But on the traits of vase life at 5% and petals Brix degree at 1% was not significant. Comparison of treatment means indicated that treatment with 150 nl l-1 1-MCP compared with the control increase vase life by 1/2 day and had the greatest impact
