La investigación se centra en las líneas avanzadas desarrolladas a través de cruces interespecíficos entre Oryza sativa L. ssp. japonica x Oryza rufipogon G., y la línea tipo japónica, cuya tolerancia a las sales bajo condiciones de invernadero y campo se sometieron a evaluación. En la primera fase en invernadero, se sembraron 24 líneas avanzadas de arroz F5, cinco líneas parentales y un cultivar comercial SFL-011 (control) en medio líquido con una concentración de 7,0 dS/m CE salinizado con NaCl y control con 0,2.dS/m CE de agua de riego. En la segunda fase en condiciones de campo se evaluaron líneas de arroz F6 en suelos salinos con 7.44 dS/m CE. Se midieron variables agronómicas y de rendimiento. En condiciones de invernadero se destacaron seis líneas: Puyón/JP003 P11-106716, Puyón/JP002 P8-30552, Puyón/JP003 P11-103115, Puyón/JP002 P8-294930, JP002/JP001 P × P 5P 1322 y JP001/JP003 P1 × 11P 413, con mayor tolerancia que el control en cuanto a vigor de planta, panículas por planta, granos por panícula, peso de 1000 granos y rendimiento (g/planta). En condiciones de campo, dos líneas, Puyón/JP003 P11-106716 y Puyón/JP003 P11-103115, se destacaron por tener mejores resultados agronómicos en cultivares y rendimiento. Los resultados mostraron la importancia del uso de cruces interespecíficos entre O. Sativa ssp. japonica x O. rufipogon, y la línea tipo japónica para mejorar la tolerancia a la salinidad del arroz y garantizar altos rendimientos potenciales en suelos salinizados; de ahí la importancia del cruce en términos de rendimientos agrícolas.
The mortiño (Vaccinium floribundum) is characterized by its high content of polyphenols and anthocyanins, as well as high antioxidant activity. This research analyzed the effect of drying (convection drying and lyophilization) together with the degree of ripeness (50% and 100%) on the fruit’s antioxidant properties. Additionally, a sensory evaluation of an infusion prepared with the dried product was conducted. The treatment consisting of lyophilization and 100% ripeness had the highest values for polyphenols and anthocyanins, 4733.50 mg of gallic acid/100 g DW and 778.70 mg of cyanidin 3-glucoside chloride / 100 g DW, respectively. The ascorbic acid content was highest in the treatment with lyophilization and 50% ripeness, with 69.50 mg / 100 g DW. The antioxidant activity for the treatments with 100% ripeness had similar results for convection drying and lyophilization, 87.28 and 88.62 mmol TE / kg DW, respectively. An infusion was made from the dried mortiño product and subjected to a sensory evaluation from a panel of tasters. The samples with 100% ripeness, regardless of the drying method, received a “Like very much” qualification for color, aroma, and taste attributes. Testing for antioxidant activity, it was found that between 2.5 to 3.5 % of the original antioxidant content is transferred to the infusion. The findings suggest that mortiño can be used in the preparation of an infusion with functional properties, creating an opportunity for the local communities of venturing into this crop for industrial purposes.
