Aluminium (Al) is the third most abundant metallic element in soil but becomes available to plants only when the soil pH drops below At those conditions, plants present several signals of Al toxicity. As reported by literature, major consequences of Al exposure are the decrease of plant production and the inhibition of root growth. The root growth inhibition may be directly/indirectly Cited by: is depressed by iron. The higher the iron level, the less the manganese uptake, and at a low manganese level, manganese translocation from the roots to the shoot is promoted by higher iron levels.

Iron is considered a micro-nutrient because only small amounts are required to aid in normal plant growth. It plays an important role in respiration.   Aluminum causes many morphological changes in root surface of different plants. It has been shown that exposure to aluminum results in decreased turgescence of epidermal cells of root tip and elongating regions, formation of a high amount of small depressions in elongating regions, destruction of epidermal cells and outer cortex cells in tip and elongation region, and formation of .

For example, manganese deficiency leads to abnormal root hairs in Arabidopsis, and the concentration of manganese, iron, and zinc is reduced in manganese-deficient conditions (Yang et al., ). The abnormal root hairs formed due to excess zinc might be caused by other factors, because the concentrations of manganese and zinc increased under.

Reactions between iron and manganese are commonly observed and the ratio of these two metals in both growth medium and plant tissue seems to be more important to plant metabolism than their concentrations [42, 43].

In this study the toxic effect of soluble inorganic aluminium on Scots pine and Norway spruce seedlings was tested at five aluminium (0, 5, 10, 20, 50 mg All−1) and two nutritional levels.   Two separate experiments were conducted to investigate the aluminium (Al) and calcium (Ca) effects on wheat seedling growth and on seed germination. Wheat (Tritcum aestivum L, cs Yangmai No. 5) seedlings were grown for a 15‐day period and treated with mM Al with low Ca (1 mM Ca) or high Ca (5 mM Ca). The growth of seedlings was. Iron deficiency in deciduous trees is indicated by yellow leaves. The degree of yellowing indicates the severity of the deficiency. If fine veins become chlorotic (yellow), and/or if leaf edges are wavy, crinkled, or curled, tree may also have manganese deficiency. Iron deficiency in conifers is indicated when the needles turn yellow. Since phosphorus (P) is known to adversely affect micronutrient nutrition, P-micronutrient interactions are also reported and discussed. Peach seedlings (Prunus persica, L. Batsch) were grown under greenhouse conditions in pots filled with soils collected either from an aged peach orchard (replant soil) or from an adjacent virgin plot (virgin.
