Nanopartículas de selenio absorbidas en hidrogeles de quitosán-polivinil alcohol en la producción de pepino injertado

Abstract

En la búsqueda por mejorar el uso de los recursos naturales y aumentar el rendimiento y la calidad de los frutos empleando técnicas amigables con el medio ambiente, como el injerto y el uso de nanopartículas metálicas. El objetivo de este trabajo fue determinar el efecto del injerto combinado con la aplicación de diferentes concentraciones de nanopartículas de selenio (Se NPs) encapsuladas en un gramo del hidrogel de quitosán-polivinil alcohol (CS-PVA) en la productividad y producción de pepino injertado. Los tratamientos fueron aplicados al sustrato al momento del trasplante de la siguiente manera: 1, 2.5 y 5 mg de NPs de Se absorbidas en un gamo de hidrogeles de CS-PVA, CS-PVA sin NPs y un tratamiento control, en plantas de pepino con injerto y sin injerto. Las variables evaluadas fueron longitud y diámetro de tallo, peso fresco y seco de hojas, área foliar, longitud de raíz, longitud de fruto, número de frutos y rendimiento por planta. Los resultados mostraron que la aplicación de las NPs de Se tienen un efecto benéfico para las plantas, como un agente promotor del crecimiento y que junto con el injerto coadyuvan a obtener una mayor altura de la planta y peso de fruto obteniendo un mayor rendimiento por planta.

Calcium, Potassium, and Magnesium Affect the Nutritional Value of Tomato Grafted Fruits Grown in a Nutrient Film Technique System

“…Regarding the factors evaluated, the results obtained in this study (Table 1) showed an increase in each of the variables that differentiate the two factors of grafted tomato plants versus non-grafted tomato plants, as well as in plant height, number of leaves, number of fruits, fruits' weight, and equatorial and polar diameters of the fruit, because a grafted plant is more efficient in the absorption and transport of water and ions from the root to the other organs, increasing the accumulation of biomass [16]. Treviño López [17] found that the effect of grafting has a positive effect on production variables, such as an increase in fruit diameter and weight compared to plants without grafting. Similar results to those of a research work where they reported an increase in fruit length, number of fruits, and yield per plant, the highest values were obtained in fruits of grafted plants [4].…”

“…The grafts increased the values of the agronomic variables, with higher values in variables such as leaf area. It may be said that the leaf area and height of the plant, which resulted in an increase of 0.96% in this variable, is reflected in a yield of 38% compared to the control [17]. A study shows that tomato fruits from grafted plants with Multifort/CID modified the mineral composition and improved yield [8].…”

Humic Acid and Selenium Supplementation Modulate the Growth and Antioxidant Potential of Chili under Cadmium Stress

“…This combined approach holds the potential to mitigate the adverse impacts of Cd stress on plant growth and health, thereby contributing to sustainable agricultural practices and environmental protection [23]. Additionally, humic acid's capacity to enhance nutrient uptake and promote root development could synergistically support selenium's role in bolstering antioxidant defense mechanisms and detoxification pathways within plants [24]. However, there are a few reports about the participation of the combined effect of humic acid and Se in the mitigation of Cd stress in terms of biochemical traits in chili plants.…”

Effects of Edaphic Fertilization and Foliar Application of Se and Zn Nanoparticles on Yield and Bioactive Compounds in Malus domestica L.

“…According to the supplier, the Se NPs were of a spherical morphology, with a size range of 2-20 nm, determined by transmission electron microscopy (TEM). González-García et al [28] and Treviño-López et al [29] provided complete characterizations. We synthesized the ZnO NPs according to the procedure reported by Garza-Alonso et al [30], and they had a quasi-spherical shape and an average particle size of 16.49 nm, as determined by TEM.…”
