Influence of the propagation term on growth of Adriatic Iris

Many of the native, wild species have a potential for use in ornamental horticulture. Iris adriatica Trinajstić ex Mitić is a very attractive perennial, due to its dwarf growth habit and beautiful, decorative flowers. It represents still untapped source in ornamental horticulture and is thus of great potential value for the enrichment of floriculture market. For introduction in cultivation, it is necessary to determine the optimal method and time of plant propagation, along with other technological parameters. Vegetative propagation is often used in nursery production, since it is not time consuming and provides a uniform plant material. In this work, propagation of Iris adriatica was performed by dividing of rhizomes. Two thirds of the rhizomes were planted below ground. Propagation was done in the first decade of June and in the first decade of August. In both cases, 160 mother plants were used, that is a total of 320 plants. During the experiment, plant height and number of shoots and leaves per plant were recorded. The results showed that the optimal time for propagation of Iris adriatica by dividing of the rhizomes is the first decade of June. However, the rate of propagation was low and unsatisfactory and is thus not suitable for mass plant production.
