“…This study found that applying H 2 O 2 foliar to tomato plants can enhance metabolic acclimation in water-stressed plants and boost RuBisCO carboxylation rate and growth in plants that are always well-watered. Other studies have found that foliar H 2 O 2 promotes tolerance to abiotic stresses 16 , 17 , 20 and stimulates development in plants grown under appropriate water regimes 18 , 21 .…”

The current climate change setting necessitates the development of methods to mitigate the effects of water scarcity to ensure the sustainability of agricultural activities.f Hydrogen peroxide (H2O2) is a plant signaling molecule that can trigger metabolic defense mechanisms in response to adverse environmental circumstances like as drought. The purpose of this study was to investigate if foliar application of H2O2 stimulates modifications in photosynthetic metabolism for adaptation of tomato plants to a period of water deficit and recovery. The study, which was carried out in a factorial scheme, tested plants subjected to two water conditions (well-watered plants and plants subjected to water deficit), as well as foliar application of 1 mM H2O2 (zero, one, or two applications, 24 h after the first), and was evaluated in two moments, during the deficit period and after recovery. Foliar application of 1 mM H2O2 resulted in a 69% increase in the maximum rate of RuBisCO carboxylation in well-watered plants, contributing to tomato photosynthetic adjustment. H2O2 treatment resulted in a 37% increase in dry mass in these plants. In plants subjected to water deficiency, 2× H2O2 increased stress tolerance by reducing the maximal rate of RuBisCO carboxylation by only 18%, but in plants that did not receive H2O2 treatment, the reduction was 86% in comparison to the wet plants. Plants exposed to a water shortage and given 2× H2O2 stored sucrose in the leaves and had a 17% higher relative water content than plants not given H2O2. Thus, H2O2 foliar treatment can be used in tomato management to induce drought tolerance or to boost photosynthetic activity and dry mass formation in well-watered plants.

“…El parámetro DT de la planta se ve favorecido con una concentración de 0.21% de H2O2, conforme se aumenta la concentración del agente se observó un mayor desarrollo en raíz, hoja y contenido de clorofila. Por lo tanto, se recomienda hacer uso alternada de ambas concentraciones de peróxido de hidrógeno para el buen desarrollo El H2O2 es el factor clave en muchos procesos fisiológicos y metabólicos de las plantas (Hu et al, 2023). Durante la germinación de semillas, la aplicación exógena de H2O2 influye en el gravitropismo e induce la curvatura de la raíz primaria en guisantes y plántulas de guisantes (Zhou et al, 2018).…”

Para la población mexicana el maíz (Zea mays L.) tiene una gran importancia económica, social y cultural, por ello es importante implementar estrategias para producir maíz libre de agroquímicos persistentes y tóxicos para el medio ambiente. En el presente trabajo, se evaluó el uso del peróxido de hidrogeno (H2O2) como alternativa para potenciar el desarrollo de la plántula de maíz. Para el estudio se utilizaron dos concentraciones de 0.21%, 3% v/v de H2O2, respectivamente y una dosis de control, el estudio de los parámetros de tamaño de la planta, raíz, número de hojas, diámetro del tallo y contenido de clorofila se registraron por triplicado. Los resultados obtenidos mostraron que con una concentración de 0.3% favorece el desarrollo del tamaño de raíz, el número de hojas y el contenido de clorofila, mientras que a una concentración de 0.21% solo se observó un engrosamiento en el tallo de la plántula. El uso del H2O2 en una buena alternativa para el desarrollo del cultivo de maíz y representa una alternativa que podría evitar el uso de agroquímicos en los cultivos.

“…However, H 2 O 2 can also be used as an exogenous signal molecule, involved in the regulation of crop growth and development [45] and the process of responding to various adversity stresses. Thus, H 2 O 2 has a dual role of protection and toxicity on crops [46]. Ahmed et al reported that low concentrations of H 2 O 2 could induce the establishment of antioxidant defense mechanisms in crops [47].…”

Spinach (Spinacia oleracea L.) is a worldwide vegetable crop with rich nutritional value, and drought is the main factor restricting its growth. Magnetized water and de-electronated water have shown potential for improving yield and quality in some crops. To assess the influence of magnetized-de-electronated water (denoted magnetoelectric water) on the growth characteristics of spinach, five soil moisture gradients were developed, including 45–55%, 55–65%, 65–75%, 75–85%, and 85–95% of field capacity (FC). The results demonstrated that the influence of irrigation by magnetoelectric water on the growth of spinach was obvious. All the spinach indicators with each soil moisture gradient under irrigation by magnetoelectric water were higher than those of irrigation by conventional water, including the fresh weight of shoots, chlorophyll content, and the total nitrogen content in the leaves. In particular, the improvement in fresh weight of shoots and the total nitrogen contents in the leaves had the highest values, as demonstrated by increases of 52.26% and 25.87%, respectively, under 65–75% of the gradient of FC. Additionally, the fitting results of the photo response curve by different light response models varied. The modified rectangular hyperbolic model was the most accurate for all the treatment groups and thus was the optimized model for the photosynthetic characteristics of spinach under irrigation by magnetoelectric water analysis. The parameters of the photo response curve showed that the dark respiration rate, apparent quantum efficiency, light saturation point, and maximum net photosynthetic rate all increased following irrigation by magnetoelectric water with different soil moisture gradients compared with conventional water irrigation. These research results can provide new technical support for improving the water use efficiency of irrigation water and increasing vegetable production.
