Silicon Contribution Via Nutrient Solution in Forage Plants to Mitigate Nitrogen, Potassium, Calcium, Magnesium, and Sulfur Deficiency

Journal of Soil Science and Plant Nutrition, 2020
This study aimed to evaluate whether silicon application in the nutrient solution is efficient in relieving stress caused by nutrient deficiency (N, K, Ca, Mg, and S) in the forages BRS Zuri (Panicum maximum) and BRS RB331 Ipypora (Brachiaria ruziziensis × Brachiaria brizantha).

Magnesium deficiency decreases biomass water-use efficiency and increases leaf water-use efficiency and oxidative stress in barley plants [PDF]

Plant and Soil, 2016
In water-scarce agro-environments a clear understanding of how plant nutrients like magnesium (Mg) affect plant traits related to water-use efficiency (WUE) is of great importance. Magnesium plays a crucial role in photosynthesis and is thus a major determinant of biomass formation.

Influence of Magnesium Deficiency on Induction of Activity of Antioxidative Enzymes and Increased Tolerance to Active Oxygen-Generating Herbicides in Cucumber and Kidney Bean Plants.

Journal of Weed Science and Technology, 1998
The influence of a deficient (7μM) or sufficient (1000μM) supply of magnesium (Mg2+) on the content of Mg2+, chlorophyll and protein, and the activity of superoxide dismutase (SOD), ascorbate peroxidase (AP) and glutathione reductase (GR) were studied in cucumber (Cucumis sativus L.) and kidney bean (Phaseolus vulgaris L.) plants over an 11-day period.

Magnesium deficiency induced leaf chlorosis affects plant growth, mineral concentration and fruit quality in field pomelo trees

Journal of Agriculture and Food Research
Healthy trees are considered the foundation for high-quality pomelo production; however, leaf chlorosis frequently happens in pomelo orchards, and the reasons and adverse effects on plant growth and fruit quality are poorly understood. We conducted a field investigation with six paired groups between the yellow and green leaves of pomelo trees to ...

Phosphorus (P)-magnesium (Mg) interaction in citrus growth: High P promotes new shoot growth while accelerating old leaf symptoms in young navel orange plants under Mg deficiency [PDF]

Abstract Background and aims The interaction between phosphorus (P) and magnesium (Mg) significantly influences citrus productivity, especially under Mg deficiency. This study investigated how P availability affects growth, physiological performance, and nutrient partitioning in young navel orange plants under different Mg supplies ...

The IP amplitude of the fluorescence rise OJIP is sensitive to changes in the photosystem I content of leaves: a study on plants exposed to magnesium and sulfate deficiencies, drought stress and salt stress

Physiologia Plantarum, 2011
The hypothesis that changes in the IP amplitude of the fluorescence transient OJIP reflect changes in leaf photosystem I (PSI) content was tested using mineral‐deficient sugar beet plants. Young sugar beet plants (Beta vulgaris) were grown hydroponically on nutrient solutions containing either 1 mM or no Mg2+ and 2.1 µM to 1.88 mM SO42− for 4 weeks ...

Phospholipase Dα1 Acts as a Negative Regulator of High Mg2+-Induced Leaf Senescence in Arabidopsis

Frontiers in Plant Science, 2021
Magnesium (Mg2+) is a macronutrient involved in essential cellular processes. Its deficiency or excess is a stress factor for plants, seriously affecting their growth and development and therefore, its accurate regulation is essential.

Supplemental Foliar-Applied Magnesium Reverted Photosynthetic Inhibition and Improved Biomass Partitioning in Magnesium-Deficient Banana

Horticulturae, 2022
Magnesium (Mg) is an essential macronutrient in plants and plays a critical role in numerous physiological processes. Therefore, Mg deficiency severely affects plant growth and crop production. This study aimed to investigate the effects of Mg deficiency

Deficiencies of Secondary Nutrients in Crop Plants—A Real Challenge to Improve Nitrogen Management

Agronomy, 2022
Secondary nutrient (e.g., calcium, magnesium, sulfur) deficiencies in crop plants disturb the nitrogen balance in the plants, thus reducing the overall yield.
