Abstract

Effective sterilization protocols are crucial for a successful tissue culture study in Aronia. These protocols directly influence contamination rates, shoot health, and root development. In this context, the aim of the study is to develop an effective sterilization protocol for plant tissue culture studies in Aronia [Aronia melanocarpa (Michaux) Elliot], commonly known as the "superfruit." In study, shoot tips of the Nero Aronia variety were used as material. The sterilized shoot tips were transferred to the respective plant tissue culture media in a randomized parcels trial pattern with three replicates, each containing three explants per replicate. Various concentrations and combinations of sterilizing agents, such as sodium hypochlorite (NaOCl), hydrogen peroxide (H2O2), mercuric chloride (HgCl2), and ethanol (C2H5OH), were evaluated to determine their effectiveness in maintaining tissue health and reducing contamination. A total of twelve protocols were developed, incorporating different concentrations of these chemicals. The results showed that the combination of 5% NaOCl and 3% H2O2 provided the lowest average contamination rate (5%) and the highest average number of healthy (uncontaminated) explants (9.00 piece), demonstrating the sterilization efficiency of this combination. On the other hand, protocols containing HgCl2, especially at higher concentrations, resulted in impaired root development. High ethanol concentrations also contributed to effective sterilization, with the combination of 7% NaOCl and 80% ethanol yielding a low contamination rate (8%) and preserving tissue health. This study emphasizes the need to balance sterilization protocols between effective contamination control and tissue viability. The findings are expected to benefit the improvement and development of tissue culture techniques for Aronia and similar species, providing a basis for further research on effective sterilization practices, which are currently limited in Aronia tissue culture.
