This study was conducted to determine effect and mechanism of exogenous silicon (Si) on salt and drought tolerance of Glycyrrhiza uralensis seedling by focusing on the pathways of antioxidant defense and osmotic adjustment. Seedling growth, lipid peroxidation, antioxidant metabolism, osmolytes concentration and Si content of G. uralensis seedlings were analyzed under control, salt and drought stress [100 mM NaCl with 0, 10 and 20% of PEG-6000 (Polyethylene glycol-6000)] with or without 1 mM Si… 
Exogenous silicon relieve drought stress and salt stress of Glycyrrhiza uralensis seedlings by regulating proline metabolism and nitrogen assimilation
ABSTRACT This article studies the effect and mechanism of Si on drought and salt tolerance of Glycyrrhiza uralensis by focusing on the pathways of proline metabolism and nitrogen assimilation. G.
Exogenous Silicon and Proline Modulate Osmoprotection and Antioxidant Activity in Cowpea Under Drought Stress
Abstract Exogenous application of proline and silicon could improve drought tolerance mechanisms in cowpea. In this study, we assessed the exogenous application of proline and silicon to reduce
Beneficial role of exogenous silicon on yield, antioxidant systems, osmoregulation and oxidative stress in fenugreek (Trigonella foenum-graecum L.) under salinity stress
In the Earth’s crust, silicon (Si) is the most abundant element after oxygen, while, under salt stress, its role in the tolerance of aromatic and medicinal plants (AMPs) is not yet detailed. For this
Physiological Responses and Antioxidant of Wheat Cultivars in PGR -Mediated Alleviation of Drought Stress
Drought is one of the most important abiotic stresses and factors limiting the successful production of plant products worldwide and has adverse effects on plant growth and other metabolic processes.
Photosynthetic Properties and Structure of Leaves of Licorice Seedlings in Response to Drought Stress
Licorice (Glycyrrhiza uralensis Fisch.) is a perennial herb that has high drought resistance, and is widely used in food, pharmaceutical and cosmetics industries. Understanding the response mechanism


Silicon nutrition alleviates the lipid peroxidation and ion imbalance of Glycyrrhiza uralensis seedlings under salt stress
Soil salinity reduces growth of Glycyrrhiza uralensis in arid and semi-arid areas of north-west in China. Silicon (Si) nutrition may alleviate salt stress in many crops including grain crop, fruit
Effect of silicon on seed germination and the physiological characteristics of Glycyrrhizauralensisunder different levels of salinity
Results indicated that Si was directly involved in the physiological process of seed germination and seedling growth in G. uralensis under salt stress conditions, and that the effect was dependent on the level of salt stress and on Si concentration.
Effects of Salt-Drought Stress on Growth and Physiobiochemical Characteristics of Tamarix chinensis Seedlings
Results showed that the influence of salt stress on growth was greater than drought stress, the oxidation resistance of SOD and POD weakened gradually with salt and drought stresses intensified, and the content of MDA was higher under severe drought and mild and moderate salt stresses.
Physiological and Biochemical Responses of Leaves and Roots of Alfalfa(Medicago sativa L.) to Water Stress
The results show that the osmotic adjustment capability and anti-oxidative enzymes activity were stronger in leaves than those in roots, and there were differences in anti-Oxidative enzyme activities and enduring capability to water stress between two tested alfalfa cultivars.
Analysis of antioxidant enzyme activity during germination of alfalfa under salt and drought stresses.
Mechanisms of silicon-mediated alleviation of drought and salt stress in plants: a review
The potential for improving plant resistance to drought and salt stress by Si application is highlighted and a theoretical basis for application of Si in saline soils and arid and semiarid regions worldwide is provided.
Interactive Effects of Drought and Salinity Stresses on Growth and Osmotica of Naked Oat Seedlings
It was suggested that under mild and moderate drought stresses, moderate soil salinity could alleviate the inhibitory effect of drought stress on naked oat seedlings growth, but its excessive salinity aggravate the deleterious effects of drought Stress.
Effect of salt and osmotic stresses on germination in durum wheat (Triticum durum Desf.)
It was concluded that stress inhibition of germination could not be attributed to an inhibition of mobilisation of reserves and that the main effect of PEG occurred via an inhibited of water uptake while detrimental effects of NaCl may be linked to long-term effects of accumulated toxic ions.
Silicon Improves the Tolerance to Water-Deficit Stress Induced by Polyethylene Glycol in Wheat (Triticum aestivum L.) Seedlings
Drought stress usually causes a serious yield reduction in wheat production. Silicon (Si) has been reported to be able to alleviate drought stress damage; however, the mechanism is still poorly
Influence of Silicon on Sunflower Cultivars under Drought Stress, I: Growth, Antioxidant Mechanisms, and Lipid Peroxidation
It can be concluded that applied Si alleviates drought stress in sunflower cultivars by preventing membrane damage, although the cultivars showed genotypic variation in response to applied Si.
