“…More than that, the SiO2 application partially mitigates the effects of 10 mM NaCl stress by raising chlorophyll a and b contents (p < 0.05). These findings are also in agreement with data obtained by González-Moscoso et al (2021), where the presence of the additional SiO2, led to the improved photochemical efficacy in tomato plants.…”

In recent years, silicon dioxide (SiO2) particles have drawn increasing attention due to their potential to enhance plant tolerance to various stresses by modulating physiological and biochemical processes. Salinity is an important abiotic stress with a harmful impact on crop growth and productivity. In this context, the aim of this study was to investigate the influence of silicon dioxide (SiO2) addition on milk thistle (Silybum marianum (L.) Gaertn.) under salinity stress. Thus, individual and combined effects of the application of sodium chloride (NaCl, 50 and 100 mM) and SiO2 particles (0.1 mM) on some physiological and oxidative stress parameters, such as growth variables, photosynthetic pigments and soluble protein contents, the levels of an oxidative stress biomarker (malondialdehyde), and the specific activity of several antioxidant enzymes (superoxide dismutase, catalase and peroxidase) were evaluated. The results revealed that salt stress (100 mM) inhibited plant growth and decreased chlorophyll and carotenoid levels, whereas the added SiO2 partially mitigated these negative effects. In addition, the 100 mM NaCl treatment significantly increased peroxidise (POD) activity and decreased soluble protein content after 22 days, while no significant differences were found for group subjected to salt stress in the presence of SiO2. Results suggest that application of SiO2 on salt-stressed milk thistle may modify the seedling metabolism and increase the plant salt tolerance capacity.

Silicon Nanoparticle-Induced Regulation of Carbohydrate Metabolism, Photosynthesis, and ROS Homeostasis in Solanum lycopersicum Subjected to Salinity Stress

Agricultural crops are facing major restraints with the rapid augmentation of global warming, salt being a major factor affecting productivity. Tomato ( Solanum lycopersicum ) plant has immense nutritional significance; however, it can be negatively influenced by salinity stress. Nanoparticles (NPs) have excellent properties, due to which these particles are used in agriculture to enhance various growth parameters even in the presence of abiotic stresses. The objective of this study was to investigate the effects of silicon NPs (Si-NPs) through root dipping and foliar spray on tomato in the presence/absence of salt stress. Plant root and leaf were used for the measurements of morphological, physiological, and biochemical parameters treated with Si-NPs under salt stress. At 45 days after sowing, the activity of antioxidant enzymes, photosynthesis, mineral concentration, chlorophyll index, and growth attributes of tomato plants were measured. The developmental processes of tomato plants were severely slowed down by salt stress upto 35.8% (shoot dry mass), 44.3% (root dry mass), 51% (shoot length), and 62% (root length), but this reduction was mitigated by the treatment of Si-NPs. Application of Si-NPs significantly increased the growth attributes (height and dry weight), mineral content [magnesium (Mg), potassium (K), copper (Cu), iron (Fe), manganese (Mn), zinc (Zn)], photosynthesis [net photosynthetic rate ( P N ), stomatal conductance (gs), transpiration rate ( E ), internal CO 2 concentration (Ci)], and activity of antioxidative enzymes including superoxide dismutase and catalase in salt stress. Foliar application of Si-NPs in tomato plants appears to be more effective over root dipping and alleviates the salt stress by increasing the plant’s antioxidant enzyme activity.
