The influence of silicon (Si, 3 mM), sodium chloride (NaCl, 135 mM), and Si, 3 mM + NaCl, 135 mM supply on chlorophyll content, photosynthetic activity (CO2 -fixation), the concentration of malondialdehyde (MDA) and H2O2, activities of superoxide dismutase (SOD), catalase (CAT) enzymes, free proline and protein contents were studied in maize seedlings leaves after two month of treatments. The results indicated that silicon partially offset the negative impacts and increased tolerance of maize… Expand

Physiological Parameters of Silicon-Treated Maize Under Salt Stress Conditions
The effects of silicon (Si) on Zea mays under salt stress conditions were investigated and the data was analyzed by cluster heat maps. The results indicated that the application of Si inExpand
Silicon mediated improvement in the growth and ion homeostasis by decreasing Na+ uptake in maize (Zea mays L.) cultivars exposed to salinity stress.
TLDR
The addition of Si alleviated salt toxicity, which was more obvious in P1574 relative to Hycorn 11 as demonstrated by an increasing trend in RWC, MSI, and activities of SOD, POD, APX and CAT, and showed a new dimension regarding the beneficial role of Si. Expand
Exogenous Silicon Enhanced Salt Resistance by Maintaining K+/Na+ Homeostasis and Antioxidant Performance in Alfalfa Leaves
TLDR
Exogenous Si application enhanced salt tolerance of alfalfa through improving the leaves photosynthesis, enhancing antioxidant performance and maintaining K+/Na+ homeostasis in leaves through improving and protecting the leaves from Na+ toxicity and thereby maintained higher chlorophyll retention.

Silicon mediated biochemical changes in wheat under salinized and non-salinzed solution cultures
Silicon (Si) can alleviate salinity damage, a major threat to agriculture that causes instability in wheat production. We report on the effects of silicon (150 mg L -1 ) on the morphological,Expand
Beneficial effects of silicon nutrition in alleviating salinity stress in hydroponically grown canola, Brassica napus L., plants
TLDR
Silicon nutrition ameliorated the deleterious effects of salinity on the growth of canola plants through lower tissue Na+ contents, maintaining the membrane integrity of root cells as evidenced by reduced lipid peroxidation, increased reactive oxygen species scavenging capacity and reduced lignification. Expand
Silicon nutrition alleviates physiological disorders imposed by salinity in hydroponically grown canola (Brassica napus L.) plants
TLDR
Silicon nutrition decreased oxidative stress in plants, evidenced by increase in antioxidant enzyme activity, reduction in hydrogen peroxide and lipid peroxidation, and higher levels of essential minerals like K+, P and Fe were maintained in plants. Expand
Benefits of Silicon Nutrition on Growth, Physiological and Phytochemical Attributes of Basil upon Salinity Stress
In the present study, improvement of salt tolerance in basil (as a salt-sensitive plant) was investigated through silicon (Si) nutrition. Basil plants were subjected to silicon (0, 3 mM) and salinityExpand
Effects of exogenous silicon on seed germination and antioxidant enzyme activities of Momordica charantia under salt stress.
TLDR
It is suggested that exogenous silicon may increase GR, GI and VI, which contributes to reducing MDA contents and increase the antioxidant enzyme activities under NaCl stress. Expand
THE EFFECT OF SILICON FOLIAR AND ROOT APPLICATION ON GROWTH, PHYSIOLOGY, AND ANTIOXIDANT ENZYME ACTIVITY OF WHEAT PLANTS UNDER CADMIUM TOXICITY
Silicon (Si) application can boost plant growth and physiology under heavy metal toxicity. The article aimed to investigate how the foliar and root application of silicon (Si) affects the uptake,Expand
Comparative Response of Salt Tolerant and Salt Sensitive Maize (Zea mays L.) Cultivars to Silicon
Salinity stress is one of the most devastating stressful environments for plant growth and production. Two Zea mays cultivars, salt sensitive (Trihybrid 321) and salt tolerant (Giza 2), were grown inExpand

Antioxidant responses of rice seedlings to salinity stress
TLDR
It is indicated that free radical-mediated damage of membrane may play an important role in the cellular toxicity of NaCl in rice seedlings and that salt-tolerant varieties exhibit protection mechanism against increased radical production by maintaining the specific activity of antioxidant enzymes.

Ameliorative effects of proline on salt stress-induced lipid peroxidation in cell lines of groundnut (Arachis hypogaea L.)
TLDR
The addition of proline to the culture medium alleviated the salt stress-induced decline in fresh weight accumulation and reduced peroxidative damage to the lipid membranes, both in a concentration-dependent manner. Expand
