JUAREZ-ROSETE, Cecilia Rocío et al. Rooting media and application of auxins in the production of strawberry seedlings. Cienc. Tecnol. Agropecuaria [online]. 2020, vol.21, n.1, pp.71-83.  Epub 30-Dez-2019. ISSN 0122-8706.  https://doi.org/10.21930/rcta.vol21_num1_art:1319.

The production of strawberry with root ball is a somewhat spread propagation technology with which vigorous, healthy, and productive plants can be obtained. The purpose of this research was to evaluate the effect of three rooting media and the application of auxins in strawberry seedling propagation. The experiment was carried out under mesh shade conditions, establishing primary stolons of the Chandler strawberry cultivar in polystyrene foam containers with alveolus of 118 mL, and one stolon per container. The treatments comprised three types of substrates: perlite, pumice and peat, and water with and without the application of indol- 3-butyric acid (IBA). Three destructive samplings were carried out at 42, 58, and 72 days after stolon establishment. The experimental design was com- pletely randomized with three replicates, each comprising ten plants in a factorial arrangement. The variables assessed were the following: mortality rate, plant height, crown diameter, number of lea- ves, leaf area, fresh and dry weight of stem and root, and root quality. The results showed that the type of substrate affects root growth and plant canopy, being pumice the substrate in which higher-quality seedlings were obtained. In general, the exogenous application of auxin did not favor the development of seedlings during the evaluated period.
