The uptake of S, P, Cu, Fe, Ca and Al were markedly affected under Zn stress. Carbohydrate and nitrogen metabolites decreased in tea leaves under Zn deficiency. Catechins increased in tea leaves to withstand Zn excess. The higher level of nicotinamide promoted energy metabolism in Zn-moderate leaves. Coordination of elements and metabolites in tea plants enhanced Zn tolerance.
