Abstract
One year‐old trees of Marianna 2624 (Prunus cerasifera X P. munsoniana), grafted with French prunes (P. domestica) were grown in the greenhouse in pots containing vermiculite and supplied with graded amounts of sulfate‐sulfur (SO4‐S) to study the sulfur (S) distribution in the trees and elemental composition as affected by S additions. Leaf, stem, bark, wood, and root samples were analyzed for different S fractions. Tissue nitrogen (N), phosphorus (P), and boron (B) concentrations decreased with S application, and that of potassium (K) and iron (Fe) were increased. Roots and leaves contained higher concentrations of S than the other tissues. Sulfur concentrations increased with the shoot height.
