HERNANDEZ-PEREZ, Melisa M. et al. Effect of silver nitrate (AgNO3) on the in vitro growth of Anthurium magnificum Linden shoots. Rev. colomb. biotecnol [online]. 2023, vol.25, n.2, pp.88-96.  Epub Feb 05, 2024. ISSN 0123-3475.

Anthurium magnificum Linden is an important ornamental plant belonging to the Araceae family. This species is in great demand as a pot plant for interior and garden decoration, as well as cut foliage. The traditional propagation methods in this species have certain disadvantages, which is why they cannot satisfy the growing demand. These limitations make plant tissue culture the most efficient method to propagate Anthurium magnificum plants at a faster rate than conventional propagation methods. In the culture of plant tissues, silver nitrate added to the culture media acts as an inhibitor of the action of ethylene and plays a crucial role in the regulation of essential physiological processes in plants. The objective of this work was to determine the effect of different concentrations of silver nitrate on the in vitro growth of Anthurium magnificum shoots. For this, in vitro shoots of Anthurium magnificum were cultivated in culture media enriched with different concentrations of silver nitrate. The results showed that the highest values in the variables plant height, number of roots and length of the roots were obtained in a culture medium with 1.0 mg L-1 of silver nitrate. In the variable leaf area of the plant, the highest values were presented in the culture media that contained silver nitrate, regardless of the concentration used.
