Zinc deficiency [ Horticulture - Phytopathology ]


	Absence or insufficiency of zinc needed for normal growth and development.

Disorders caused by zinc deficiency include reduction in leaf size and a shortening of internode lengths. Stem growth retardation is thought to be due to the deficiency of zinc prohibiting sufficient production of the growth hormone, auxin. Interveinal chlorosis (a yellowing of the leaf tissue between the veins) may also occur with zinc deficiency.
