<abstract xmlns="http://www.w3.org/1999/xhtml"><p>The purpose of this paper is to examine the effects of commercial plant growth regulators (PGRs), namely Inict-1 and Incit-5, on the rooting of African violet leaf cuttings (Saintpaulia ionantha H.

The propagated plant material of the cultivar ‘Nagano’ was treated with Incit-1 and Incit-5. The following parameters were observed: the occurrence of the first root, the number of formed secondary roots and root lengths, the occurrence of the first leaf, and the occurrence of the first flower. The results obtained showed that the use of commercial rooting hormones, namely Incit-1 and Incit-5, exerted positive effects on the duration of rooting, the number of secondary roots formed, and the root lengths of African violets. During the research, it was observed that the rooting durations of all the plants treated with Incit-1 and Incit-5 were 5 days shorter.
