The influence of treatments applied to common ninebark (Physocarpus opulifolius (L.) Maxim.) ‘Diabolo’ cuttings on their rooting and growth
Summary.

Background. As synthetic auxins are prohibited, it is necessary to conduct research to assess the suitability of other substances used for propagation of ornamental bushes to improve the rooting of cuttings and the growth of plants. The aim of the experiment was to compare the effectiveness of a mycorrhizal inoculum and effective microorganisms in the production of ninebark shrubs.

Material and methods. Between 2010 and 2012 an experiment on Physocarpus opulifolius ‘Diabolo’ was conducted to assess how three different treatments applied to cuttings influenced their rooting and growth. Before hardwood cuttings were planted in a field, they had been treated with an endomycorrhizal inoculum, effective microorganisms and Ukorzeniacz AB Aqua. The diameter and length of the shoots were measured. The number of shoots was counted, the percentage of rooted cuttings was calculated and the fresh mass of the root system was weighed.

Results. The mycorrhizal inoculum increased the percentage of rooted cuttings and gave the best results in the diameter and length of lateral shoots as well as the fresh mass of the root system of the bushes. The effective microorganisms (EM) resulted in the highest percentage of rooted cuttings and the largest number of lateral shoots. The EM preparation improved the diameter and fresh mass of the root system. The Ukorzeniacz AB Aqua improved the rooting of the cuttings and increased the diameter and fresh mass of the root system.

Conclusions. The mycorrhizal inoculum improved the rooting of the cuttings and stimulated the growth of the shrubs. The effective microorganisms increased the percentage of rooted cuttings, as the Ukorzeniacz AB Aqua did, and improved the growth of the plants.
