deficiency symptoms of nickel in plants

Nickel (Ni)—a component of urease and hydrogenase—was the latest nutrient to be recognized as an essential element for plants. Plants supplied 0 μM Ni developed Ni deficiency symptoms; Ni deficiency resulted in the disruption of nitrogen metabolism, and affected the concentration of malate and various inorganic anions in roots, shoots, and grain of barley. Plants absorb Ni as the divalent cation Ni 2+.It is required in very small amounts, with the critical level appearing to be about 1.1 parts per million. Unlike the other micronutrients, molybdenum-deficiency symptoms are not confined mainly to the youngest leaves because molybdenum is mobile in plants. trace elements, metals, nutrition, yield, over fertilization, zinc Keywor s This communication reports that the mouse-ear or little-leaf disorder and the associated replant disease of pecan ICar.vu illinoinensis (Wangenh.) In ornamental potted plants, Mo deficiency is not common, except for poin-settia. Micronutrient deficiencies are common in Indian soils which are leading to low yields, low mineral content in seed and fodders and thus adversely affecting plant, animal and human health. Nickel deficiency can either be a result of low availability in soil, or could be induced by several factors, including: high contents of Ca, Mg, Cu, or Zn; availability decreases with excessive application of lime, when pH is raised above 6.5; high soil P limits availability either in the soil or within the plant itself; or nematodes can damage the root system and lead to severe deficiency.
