“…Leaf TSP content for clones OC-61 and BR-05 were similar to values previously reported for different Trinitario clones of a germplasm bank in Barlovento, Venezuela, in which values between 1.6 and 8.8 mg g -1 have been found (Quiñones-Gálvez et al, 2015;Tezara et al, 2020). Clone OC-61 presented higher values of TSP compared to BR-05, with values between 5.1 and 6.9 mg g -1 in OC-61 and between 4.3 and 5.4 mg g -1 in BR-05.…”

Summary Studies on the effect of nanofertilizers (NF) in physiological performance of plants is scarce, especially that related to substances encapsulated into silicon dioxide (SiO2) nanoparticles in cocoa plants. The effect of foliar application of SiO2-NF on nutrient contents, gas exchange, photochemical activity, photosynthetic pigments, total soluble protein (TSP), photosynthetic nitrogen use efficiency (PNUE), and growth in seedlings of two cocoa clones (OC-61 and BR-05) in a greenhouse was assessed. Spraying with SiO2-NF increased net photosynthetic rate (A) by 16 and 60% and electron transport rate (J) by 52 and 162% in clones OC-61 and BR-05, respectively, without changes in photosynthetic pigment concentration in either clone. The SiO2-NF caused a decrease of 37 and 22% in stomatal conductance in OC-61 and BR-05, respectively; a similar trend was observed in transpiration rate, causing an increase of 42 and 100% in water use efficiency in OC-61 and BR-05, respectively. In both clones, diameter of graft increased on average 28% with SiO2-NF. Higher photosynthetic capacity was related to an increase in leaf N, P, and TSP. A significant reduction in PNUE (A/N ratio) was found in OC-61, whereas in BR-05 PNUE increased after spraying with SiO2-NF. Overall, spraying with SiO2-NF had a positive effect on photosynthetic processes in both cocoa clones, associated with an increase in nutrients content, which translated into improved growth. A differential physiological response to spraying with SiO2-NF between clones was also found, with BR-05 being the clone with a better physiological response during the establishment and development stages.

Objective: To evaluate the lipid-lowering activity of an aqueous extract obtained from the seeds of Phaseolus vulgaris in male mice using the hyperlipidemia induction model with Triton X-100. Methods: the chemical quality of the extract obtained was characterized by quantifying the total polyphenols (Folin Ciocalteu method) and total anthocyanins (colorimetric method) as well as their antioxidant activity by their ferric ion reducing capacity (FRAP, TPTZ method). Results: The data obtained show that the aqueous extract contains a large amount of total polyphenols (415 mg EAG / 100g of seed) and total anthocyanins (43EMG / 100 g of seed) and significant antioxidant activity (11.080.83 of Fex / g of seed). Administration of the aqueous extract to hyperlipidemic mice improved their lipid profile, especially by reducing the serum value of total cholesterol (144 mg/dL) and triglycerides (147 mg/dL) and increasing HDL values (67 mg/dL) in the group that received a dose of 300 mg of extract / kg of weight. Conclusion: These results show that the aqueous extract of P. vulgaris exerts an antioxidant activity in vitro and a lipid-lowering effect in mice.

Las infusiones aromáticas tienen aceptabilidad en el sector agroindustrial, no obstante, es una forma para aprovechar las hojas del Theobroma cacao L. El objetivo del estudio fue evaluar la calidad física de las hojas, calidad microbiológica y organoléptica de las infusiones. Se empleó un diseño de bloques completamente al azar en parcelas divididas como primer factor o parcela grande las variedades de cacao (Nacional, Forastero y Trinitario) como parcela pequeña hojas de cacao (jóvenes – parte alta del árbol y maduras – parte baja del árbol) con tres repeticiones. Las variables físicas evaluadas fueron: pH con una media de 6,64, grados brix 1,44%, humedad 11,02% y ceniza 11,67%; microbiológicas: E. coli/Coliforme presentó ausencia de UFC/g. Con relación a los análisis organolépticos el T6 presentó mejor color, el T5 mejor olor y el T1 mejor sabor y aceptabilidad. Los resultados de los análisis físicos y microbiológicos mostraron cumplimiento según las especificaciones de las normas NTE INEN 2381 para el té y NTE INEN 2392 para las hierbas aromáticas. Sin embargo, se observa que el producto T1 muestra mayor aceptabilidad en los análisis organolépticos, indicando una oportunidad para mejorar la calidad organoléptica y en el posicionamiento de la marca en el mercado.
