“…Nimfa, a correlation between Mn and Ca (r = 0.997) was noted when Mn was administered alone. The reduced uptake of the studied elements under Mn stress was demonstrated earlier in the leaves of various plant species (Juice et al 2006;Kleiber 2014). Also, in chloroplasts of wheat seedlings, diminished accumulation of Zn, Cu, Fe, Mg and Ca was shown under Mn stress (Sieprawska et al 2017).…”

Purpose Agronomic practices are one of the reasons for the increasing accumulation of elements in the soil, including manganese (Mn). Our previous studies have shown that selenium (Se) ions can reduce the toxic actions of metal stress. Those, we studied the effects of Mn—treated as a stressor and Se – as a potential defense in plants. Methods Mn ions (10 mM) or/and Se (15 μM) were added into hydroponic nutrients of two wheat cultivares. The evaluation of the stress-generating and protective actions were analyzed by biochemical methods and microscopic observations in leaves and roots. Moreover the level of DNA methylation for these tissues was determined. Results Mn application caused an increase of lipid peroxidation and hydrogen peroxide content in both leaves and roots and was accompanied with a greater absorption of this element by the roots. For other elements (K, Fe, S, P), with the exception of Ca, the reduced their uptake was registered, especially in roots. For roots, Mn stimulated greater, microscopically observed, desorganization in cell structure as compared to leaves, which was accompanied by a quantitative increase in 5-methylcytosine (5-metC) in root meristem. Se application diminished the effects of Mn-stress. Conclusions These studies is the first in which indicated that global 5-metC level in roots enhancing from dividing meristematic cells to elongating cells of the axial cylinder and cortex. It was suggested that the rise in Ca level can lead to modification of root cells differentiations what may be one of the steps in defense mechanisms.

“…The novelty of our studies was not only connected with bio-fortification of lettuce with Se, but also a significant reduction of heavy metal contents, including Mn, with an important improvement of plant yield. The Mn concentration in lettuce leaves in the case of plants grown with the standard cultivation (0.5 mg Mn dm -3 ) is 328.4 mg kg -1 DM [7]. With an increase to an excessive level (19.2 mg Mn dm -3 ) the content of Mn in leaves increased about 1.5 times.…”

“…Because of its sensitivity to oxidative stress induced by excessive concentrations of Mn a model plant in our studies was a lettuce [7]. The aim of the conducted study was to determine the allevation effect of Se nutrition on plant yield and the concentrations of Mn, Se, and also other macro-and microelements in leaves of lettuce grown under strong Mn stress.…”

Excessive (without visual symptoms on plants) or toxic (with present visual symptoms of necrosis) contents of Mn in water/nutrient medium cause a significant accumulation of this nutrient in different edible parts (fruits and leaves) of vegetable species [7,8].

Mn, as Fe, Zn, Cu and Ni is a heavy metal and also a necessary element all the living organisms. Excessive Mn nutrition causes a strong oxidative stress. The aim of the studies was to determination the effect of Se treatment (as sodium selenite Na2O4Se3) to alleviate the Mn stress of plants. Because of its sensitivity to oxidative stress induced by excessive concentrations of Mn a model plant was lettuce (Lactuca sativa L. 'Sunny'). ). In all the combination were also tested different foliar sprays (distilled water and a 0.005% Se solution). Plants grown under conditions described above take up and transported Se from nutrient solutions into their leaves with a significant reduction of Mn concentration and changes in the plant nutrient status. With the increase in the concentrations of Se clearly narrowed quantitative relations in the leaves between this element and micro-metallic. Increasing Se levels in nutrient solution has a positive influence on the growth of plants, but Se foliar treatment generally decreases plant yield. The study shown that Se application may lead to alleviation of Mn stress of plants, with simultaneous reduce in Mn concentration in leaves -which may be of practical importance also in the cultivation of more economically important species.

Hydroponics is a plant cultivation technique that uses water as a growing medium. The acidity level (pH) of water is an important factor in the success of hydroponic plant cultivation. High water acidity (pH>8) can be controlled by adding acid solution to a pH level of 5.8-7.0. This research was conducted to examine the nutrient content of lettuce. The research used a Randomized Block Design with 9 treatments (3 types of water and 3 types of acid solution). The types of water used include Kebonsari well water, Bugul Kidul well water and Pasuruan city PDAM water. The acid solutions used include nitric acid, phosphoric acid and sulfuric acid. The results of the research show that adding acid solutions to all types of water produces different plant nutrient contents. The addition of nitric acid and phosphoric acid solutions respectively had a significant effect on the N and P nutrient content of lettuce plants. The addition of phosphate solution can be recommended as a pH lowering solution in hydroponic cultivation.
