Resumen
CHIPANA MENDOZA, Gladys Jaqueline. Hydropriming and liquid fertilizer of trout (Oncorhynchus mykiss) on the increase of germination and root growth in quinoa (Chenopodium quinoa Willd) and cañahua (Chenopodium pallidicaule Aellen) seeds. Rev. investig. Altoandin. [online]. 2023, vol.25, n.1, pp.14-22. ISSN 2313-2957. http://dx.doi.org/10.18271/ria.2023.459.
Liquid fish fertilizer is a good source of nitrogen, phosphorus and protein, which are essential plant nutrients. Hydropriming involves soaking the seeds in water and drying them to improve germination. A percentage of quinoa and cañahua seeds from the Andean Grains Germplasm Bank have low germination, so the objective of the research is to evaluate the effect of hydropriming and liquid trout fertilizer in increasing germination and root growth in quinoa and cañahua seeds. The research was carried out in the laboratory of the Banco de Germoplasma de Granos Andinos, La Paz (Bolivia). A sample of 100 seeds was taken from three accessions of quinoa and cañahua, and four treatments were evaluated: control (100%: 0%), treatment 1 (99.90%; 0.10%), treatment 2 (99.75%;0.25%), treatment 3 (99.50%;0.50%) and treatment 4 (99.25%;0.75%) with three replications, the soaking time was 12 hours at room temperature, then they were dried and arranged in Petri boxes, then introduced to the germination chamber for seven days at a temperature of 17°C, the length of the radicle (mm) was determined by an electronic vernier. The combination of 99.50% distilled water with 0.25% liquid trout fertilizer is the optimum to achieve higher germination percentage and root length in quinoa and cañahua seeds. The combination of 99.25% distilled water with 0.75% liquid trout fertilizer showed a decrease in both variables, which according to similar research is due to an increase in pH and a decrease in CE.
