The inability of cereal crops to complete their life cycle in the absence of Ni demonstrates that Ni is an essential micronutrient for the growth of higher plants. The growth of barley (Hordeum vulgare L., cv. Onda), wheat (Triticum aestivum L., cv. Era), and oats (Avena sativa L., cv. Astro) is depressed under Ni deficient conditions, and grain of severely Ni deficient barley was inviable. Evidence suggests that Ni is essential to the formation of the grain embryo and in the remobilization of N from the leaves to the grain during plant maturation. Nickel deficiency produces characteristic deficiency symptoms in cereals including, leaf chlorosis, premature senescence in oats, and the development of interveinal necrosis. Metabolic effects of Ni deficiency are extensive and cannot be alleviated by the addition of any other essential element.
