Zinc deficiency in Maize

症状
Pale yellow chlorotic zones running parallel to the midrib starting at base of leaves. Leaf margin, tip and midrib remain green. The youngest developing leaves may be totally clorotic yellow or white ('white bud'). A reddish to necrotic brown discolouration at the leaf margins and the stems may develop on basal plant parts, when deficiency is severe. Internode growth is reduced and leads to a stunted appearance.

原因
Severe zinc deficiency Sufficient zinc supply is very important for maize flowering and corn development. Deficiency symptoms can often be observed at wet and cold weather.

症状
Pale yellow-white chlorotic zones run parallel to the midrib starting at base of leaves, giving the leaf a streaky appearance. Symptoms generally start at the older leaves, but sometimes occur at the younger leaves first.
