Apoplastic peroxidases and ascorbate are involved in manganese toxicity and tolerance of Vigna unguiculata

Excessive manganese (Mn) supply induced the formation of brown spots on leaves as typical Mn toxicity symptoms in cowpea (Vigna unguiculata L. Walp.) grown in hydroponics. Differences in Mn resistance between cv. TVu 91 (Mn‐sensitive) and cv. TVu 1987 (Mn‐tolerant) expressed in the density of brown...
