"Little leaf" and "rosetta" are the classical symptoms of zinc deficiency in fruit trees. Both these syndromes result from failure of tissues to grow normally. Failure of leaves to expand causes little leaf, and failure of internodes to elongate causes leaves at successive nodes to be so closely telescoped as to give rise to the rossette symptom. In some species, leaves become chlorotic, but in others, leaves may be dark green or blue-green. Leaves may become twisted and necrotic. Flowering and fruiting are much reduced under conditions of severe zinc deficiency, and the entire plant may be stunted.
