What Are The Symptoms Of Manganese Deficiency In Plants? Manganese deficiency in plants can lead to various symptoms such as yellowing of leaves, interveinal chlorosis, stunted growth, and reduced fruit production. Plants lacking sufficient manganese may also exhibit leaf spots, necrosis, and poor root development.

Abstract. Manganese (Mn) toxicity in plants is often not a clearly identifiable disorder. Symptoms of Mn toxicity as well as the concentration of Mn that causes toxicity vary widely among plant species and varieties within species, perhaps because the phytotoxic mechanisms of Mn involve different biochemical pathways in different plant genotypes.
