    Evaluación del efecto de hongos endófitos con capacidad de solubilización de nutrientes y producción de AIA en el desarrollo de estacas de Macleania rupestris

    Macleania rupestris is a wild andean fruit species with nutritional, ecological, and productive potential; however, its use is limited by the lack of efficient ex situ propagation techniques. In this context, the present study evaluated the effect of endophytic fungi of the genus Trichoderma (T. koningiopsis, T. atroviride, and a mixture of both strains), applied through two inoculation methods (drench and bead encapsulation), on the development of M. rupestris cuttings, with and without tricalcium phosphate supplementation. The experiment was established under a completely randomized design with a 3 × 2 factorial arrangement plus controls, resulting in ten treatments. Vegetative growth variables and root-related variables were evaluated. Prior to statistical analysis, assumptions of normality (Shapiro–Wilk) and homogeneity of variances (Levene) were tested. Vegetative growth variables and the root variables of root length, fresh weight, and dry weight did not meet the normality assumption and were therefore analyzed using the non-parametric Kruskal - Wallis test. In contrast, the number of root sprouting sites met the statistical assumptions and was evaluated using analysis of variance (ANOVA). The results indicated that none of the evaluated variables showed statistically significant differences among treatments (p > 0.05). Under the experimental conditions assessed, Trichoderma inoculation and the inoculation methods did not generate detectable effects on the development of M. rupestris cuttings. These findings suggest a high specificity in the symbiotic interactions of M. rupestris and indicate that more specific fungal associations or longer evaluation periods may be required to detect physiological responses.
