Effects of Magnesium Sulfate Sprays on Growth and Elemental Concentration of Pecan Seedlings

Year: 1986

Type: article

Abstract: Foliar applied Mg (0.0%, 0.24%, 0.48%, or 0.96% MgSO 4 -7H 2 O) was compared to root-supplied Mg (Hoagland's solution) in pecan [ Carya illinoensis (Wan- genh.) C. Koch] seedlings. Foliar-applied Mg suppressed, but did not prevent, Mg deficiency symptoms and increased leaf concentration of Mg and seedling growth compared to plants grown without Mg. Leaf Mg and growth from foliar sprays were substantially less than for plants with root-supplied Mg. Compared to root-supplied Mg, omitting Mg increased the leaf concentration of P, K, Cu, and Zn; decreased Ca and Mg; and had no effect on N, Fe, Mn, B, and Al. The nutritional imbalances induced by Mg deficiency were alleviated by foliar-applied Mg.
