  author={D. P. Heenan and Lindsay C. Campbell},
  journal={Plant and Soil},
SummarySoybean (Glycine max (L) Merr. cv. Bragg) seedlings were grown in nutrient solutions to evaluate the response to manganese nutrition as affected by potassium supply. In solutions containing 275 μM manganese, increasing the solution concentration of potassium from 1 mM to 10 mM alleviated symptoms of manganese toxicity, decreased manganese concentrations in the leaves and increased dry matter yields of the plants. The reduction in manganese toxicity was brought about by a reduced rate of… 
Manganese and iron interactions on their uptake and distribution in soybean (Glycine max (L.) Merr.)
SummaryThe uptake and distribution of iron and manganese were studied in a manganese-sensitive soybean cultivar (‘Bragg’) grown over a range of supply levels of these nutrients in solution culture.
Mechanism of potassium alleviation of manganese phytotoxicity in barley evaluated by short-term absorption of manganese-54 and iron-59
Abstract The mechanism of K alleviation of Mn toxicity and Mn-induced Fe deficiency was studied in barley (Hordeum vulgare L. cv. Minorimugi). Plants were grown hydroponically under normal (0.25 µM
Mechanism of Potassium Alleviation of Manganese Phytotoxicity in Barley
ABSTRACT Manganese (Mn) toxicity and potassium (K) deficiency are the major factors that limit plant growth and development in acid soils. The objective of this study was to assess the role of high K
Growth and physiological response to manganese toxicity in Chinese cabbage (Brassica rapa L. ssp. campestris)
Growth and physiological characters of Chinese cabbage demonstrated tolerance upto 300 μM Mn with nutrient solution in pot culture, whereas CO2 assimilation decreased with increasing Mn.
Effects of Manganese on Uptake and Translocation of Nutrients in a Hyperaccumulator
ABSTRACT The effects of manganese (Mn) on the growth and Mn-induced changes in nutrients uptake and translocation in Mn hyperaccumulator Phytolacca acinosa was investigated in this study. Results
Growth Response of Hydroponic Rice Seedlings at Elevated Concentrations of Potassium Chloride
 A hydroponic experiment was conducted in the greenhouse to observe the effect of potassium chloride (KCl) on growth, macro elements and sodium (Na) concentration of rice seedlings (Oryza sativa L.
The iron-manganese (Fe-Mn) disorder in marigold (Tagetes erecta L.) is related to high Mn and low magnesium (Mg) in leaves. Three solution-culture experiments with marigold were conducted in a
Alleviation of cadmium phytotoxicity by magnesium in Japanese mustard spinach
Applying high amounts of Mg in the nutrient solution can alleviate Cd toxicity in plants, and Magnesium-alleviated plants showed higher shoot growth and decreased shoot Cd concentration, compared with Cd-toxic plants.
Alleviation of Manganese Phytotoxicity in Barley with Calcium
ABSTRACT In order to clarify the mechanism by which calcium (Ca) alleviates manganese (Mn) phytotoxicity, barley plants were grown under the following conditions: (1) nutrient solution alone


The effect of varied nutrient levels on the concentration and distribution of manganese within the potato plant
Summary1. Potato plants were grown in sand culture with varying levels of iron, potassium, phosphorus and calcium carbonate and an adequate supply of manganese. The concentration and distribution of
Influence of temperature on the expression of manganese toxicity by two soybean varieties
SummaryTwo soybean varieties (Glycine max) were grown in nutrient solution to investigate their response to manganese toxicity at two different temperature regimes. Dry matter yields of both
Effect of manġanese level in nutrient solution on ġrowth and maġnesium content ofPinus radiata seedlinġs
A hypothesis is presented suggesting that high levels of Mn may contribute to Mg deficiency in Pinus radiata D. Don seedlings, and that Mg uptake was inversely related to Mn supply.
Growth, yield components and seed composition of two soybean cultivars as affected by manganese supply
The influence of manganese nutrition on growth and yield of two soybean cultivars (Lee and Bragg) was studied in sand culture and no difference was found between the two cultivars.
Manganese toxicity in pasture legumes
SummaryThe effects of Ca and P levels in the substrate on Mn toxicity in several pasture legumes were studied.In solution culture, high Ca supply alleviated Mn toxicity by reducing the proportion of
Effects of calcium carbonate and ammonium sulphate on manganese toxicity in an acid soil
The results of this trial indicate that soil and plant analyses are useful for predicting manganese toxicity in acid soils.
Ion Competition in Manganese Uptake by Barley Plants.
The recommended concentration of manganese in Hoagland's solution produces toxic symptoms in barley plants andl must be reduced substantially to avoid injury to the leaves. The suggested rate of 0.5
Effects of certain cations on manganese absorption by excised rice roots
Abstract The absorption of Mn by excised rice roots was studied in the absence and presence of interfering cations like Ca, Mg, and Zn in the absorption medium. In the low concentrations of Mn, the
