Antagonistic effects of iron and/or magnesium deficiencies on enzyme activities in lettuce (Lactuca sativaL.) plants

open access: closedThe Journal of Horticultural Science and Biotechnology, 2014
Summary Lactuca sativa L. is one of the most important sources of phytonutrients including vitamins, carotenoids, and antioxidants. However, lettuce growth and quality are strongly affected by soil fertility. In this study, the influence of iron (Fe) and/or magnesium (Mg) deficiencies on the growth, anti-oxidant properties, and ferric chelate reductase

The effects of short-term deficiency of boron on potassium, calcium, and magnesium distribution in leaves and roots of tomato (Lycopersicon esculentum) plants

open access: closed, 1990
Boron deficiency frequently affects long distance transport of nutrients in plants. In this investigation K, Ca and Mg distributions in shoots and roots of tomato plants under conditions of short-time B deficiency were studied. Plants were grown in water cultures with variation in B supply: 0.0 (−B) and 0.5 (+B)mgL−1. Soluble and insoluble fractions of

Magnesium in barley plants on magnesium-deficient soils

Soil Science and Plant Nutrition, 1955
Abstract Working with fused phosphate containing Mg, we have known some of the Mg-deficient areas in Shizuoka prefecture as a field problem. In these areas, crop plants develop visual hunger signs, resulting in restricted growth and reduced yield. The manurial effect of Mg-salt added or fused phosphate is remarkably excellent in these areas or soils.

Photosynthetic plasticity aggravates the susceptibility of magnesium‐deficient leaf to high light in rapeseed plants: the importance of Rubisco and mesophyll conductance

The Plant Journal, 2023
SUMMARYPlants grown under low magnesium (Mg) soils are highly susceptible to encountering light intensities that exceed the capacity of photosynthesis (A), leading to a depression of photosynthetic efficiency and eventually to photooxidation (i.e., leaf chlorosis).

Magnesium deficiency in some crop plants in relation to the level of potassium nutrition

The Journal of Agricultural Science, 1945
While numerous studies have demonstrated the essential role of magnesium in the normal development of plants, the information as to the soil conditions governing the availability of this nutrient is relatively limited. In general it is considered that a true lack of magnesium in the soil, such as might result from leaching or overcropping, is the main ...

High Light Intensity Enhances Chlorosis and Necrosis in Leaves of Zinc, Potassium, and Magnesium Deficient Bean (Phaseolus vulgaris) Plants

Journal of Plant Physiology, 1989
Summary The effect of varied light intensities (80μEm2s-1 to 600μEm-2s-1) on chlorosis and necrosis in leaves of zinc (Zn), potassium (K) and magnesium (Mg) deficient bean (Phaseolus vulgaris L. cv. Prelude) plants was studied in water culture experiments with different Zn, K and Mg supplies.
