Vegetative Propagation of Zamioculcas zamiifolia (G. Lodd.) Engl. Managed by IBA Application, Substrate Quality, and Leaflet Cutting

Zamiifolia or ZZ is a luxury indoor ornamental plant that has received considerable attention in the last two decades. Due to its high economic value, its propagation is very important. To investigate the rooting and rhizome production by leaf cuttings, this research was conducted in two experiments. The first experiment was a factorial with two factors, i.e., IBA concentrations (۰, ۲۵۰, and ۵۰۰ mgL-۱) and three positions of leaflet cuttings on the main axis of the leaf (apical, middle, and basal). The results of this experiment showed that the number of rhizomes and roots increased in response to ۲۵۰ and ۵۰۰ mgL-۱ IBA, respectively, compared to the other treatments. treatments. In the second experiment the effects of three propagation media (۵۰:۲۵:۵۰; perlite:sand:cocopeat, ۵۰:۵۰; cocopeat:perlite and ۷۰:۳۰; cocopeat:perlite) and three positions of leaflet cuttings on the main axis of the leaf (apical, middle and basal) were investigated in a completely randomized design with three replications, in the second experiment. The results indicated that the ۵۰:۵۰ cocopeat:perlite medium significantly increased the rhizome length, rhizome width, root formation, the longest root length and number of shoot formations. In conclusion, the optimal recommendation for rhizome formation/rooting substrate was cocopeat plus perlite and IBA application is recommended for the vegetative propagation of this valuable ornamental plant.
