African violet is one of the most popular flowering houseplants around the world. The high demand of this plant requires its high production. For obtained maximum production, it is necessary to provide the suitable conditions for plant growth and an efficient propagation method. In order to increase the rooting and mass production of the African violet plant, as well as to shorten its growth and flowering period, an experiment was conducted in two separate stages in the form of a completely randomized design in Isfahan University of Technology. In the first stage, leaf cuttings were treated with Naphthalene Acetic Acid (NAA) at four levels of 0, 250, 500 and 1000 mg/L in five replications. In this stage, some traits such as the number of days until rooting, the number of rooted cuttings, the fresh and dry weight of the root, the fresh and dry weight of the shoots, the number of produced shoots and the number of leaves in each cutting were calculated. In the second stage, African violet plants were sprayed with different smoke-water concentrations (0, 1:500 and 1:1000). In this stage, traits including crown area, leaf area, number of leaves, fresh and dry weight of roots, root volume, fresh and dry weight of shoots, flowering time, time of 50% flowering, number of flowering branches, average number of flowers on flowering branch, the number of flowers per plant, flower diameter, chlorophyll a, chlorophyll b, total chlorophyll and carotenoid were eva‎luated. The results of the first stage showed that the treatment of 250 and 500 mg/L NAA significantly reached rooting in less days. The fresh and dry weight of the shoot was also higher in the control treatment than the other treatments and had a significant difference with them. In the second stage, vegetative traits of leaf surface, wet and dry root weight and root volume in the smoke-water treatment increased significantly compared to the control. In this study, the concentration of 1:500 smoke-water was able to significantly increase the reproductive traits like flower diameter, the number of flowering branches, the average number of flowers per flowering branch, and the number of flowers per plant compared to the control in the African violet plant. The concentration of 1:500 smoke-water also decreased flowering time and time of 50% flowering in this plant. In general, it can be concluded that the use of NAA increased the traits related to rooting and the use of smoke-water also increased the reproductive traits and some vegetative traits in the African violet plant.
