“…However, the use of Si in these plants did not affect lipid peroxidation and quantum efficiency of PSII, indicating that these plants did not present oxidative stress. On the other hand, in Mn-deficient plants, the benefit of Si was evidenced by increasing the quantum efficiency of PSII of energy cane plants, which was also reported in sorghum and corn plants by [15] and recently in soybeans plants [16]. The fact that there was an improvement in electron transport in Mn-deficient plants through Si may have reduced ROS accumulation, since both the preservation and improvement in electron transport in PSII maintained the formation of singlet oxygen, superoxide ions, H 2 O 2 , and hydroxyl radicals [77].…”

“…Moreover, Mn deficiency in the plant metabolism disrupts the structure of thylakoids and chloroplasts and extends damage to photosynthetic pigments, reducing the contents of these molecules [12,13]. It also impairs the functioning of Photosystem II (PSII), which is essential for the first phase of photosynthesis [14][15][16], ultimately stimulating ROS overproduction [17]. Thus, Mn deficiency is a serious nutritional disorder that compromises crop performance and limits growth.…”

Background Silicon (Si) is a multiple stress attenuator element in plants, however more research is needed to elucidate the actions in the plants defense system with low nutrition of manganese (Mn) for a prolonged period, and the attenuation mechanisms involved in the effects of Mn deficiency on energy cane with high fiber content. Thus, the objective of this study was to evaluate whether Si reduces the oxidative stress of the energy cane grown in low Mn in nutrient solution, to mitigate the effects of Mn deficiency, improving enzymatic and non-enzymatic defense, uptake of Mn the plant growth. Methods An experiment was carried out with pre-sprouted seedlings of Saccharum spontaneum L. in a 2 × 2 factorial scheme in five replications in which the plants were grown under sufficiency (20.5 μmol L−1) and deficiency (0.1 μmol L−1) of Mn combined with the absence and presence of Si (2.0 mmol L−1) for 160 days from the application of the treatments. The following parameters were evaluated: accumulation of Mn and Si, H2O2, MDA, activity of SOD and GPOX, total phenol content, pigments, and quantum efficiency of PSII. Results Mn deficiency induced the oxidative stress for increase the H2O2 and MDA content in leaves of plants and reduce the activity of antioxidant enzymes and total phenols causing damage to quantum efficiency of photosystem II and pigment content. Si attenuated the effects of Mn deficiency even for a longer period of stress by reducing H2O2 (18%) and MDA (32%) content, and increased the Mn uptake efficiency (53%), SOD activity (23%), GPOX (76%), phenol contents, thus improving growth. Conclusions The supply of Si promoted great nutritional and physiological improvements in energy cane with high fiber content in Mn deficiency. The results of this study propose the supply of Si via fertirrigation as a new sustainable strategy for energy cane cultivation in low Mn environments.

“…Ensuring su cient levels of manganese is essential for plants' overall well-being and strength, which may lead to increased protein content in grains. According to research on soybean (Glycine max), foliar spraying of Mn and Si together enhanced the grain's protein content, resulting in a 7% increase in protein content 73 . The results of our study showed that the simultaneous use of salicylic acid and manganese had a more substantial impact on the protein content of grains than using either compound alone.…”

As an oilseed crop, mustard—a plant in the family Brassicaceae—is essential in India and worldwide. Crucial to plant metabolism are manganese and salicylic acid. We performed a field experiment to determine how they affected Indian mustard (Brassica juncea). Using a Randomized Block Design with three replications, the experiment included ten treatment combinations. These included control groups, different doses of sole salicylic acid (75, 150, 300 ppm), sole manganese (0.25, 0.5, 0.75 mM MnSO4), and combinations of the two. According to the experimental results, increasing dosages of both manganese and salicylic acid reversed the effects of sole foliar application by increasing the mustard growth and biochemical properties. It is worth mentioning that the addition of 0.5 mM manganese and 150 ppm salicylic acid externally increased stem dry weight by 1.24-fold, total chlorophyll content by 2.35-fold, relative water content by 1.25-fold, grain protein content by 1.11-fold, and oil content by 1.19-fold. To top it all off, the leaf membrane injury index went down by 36.2–53.2% after the combined application. The combination of salicylic acid and manganese yielded superior outcomes in optimizing growth dynamics and quality potential compared to individual applications of either compound.
