Abstract

Abstract Foliar absorption of RbCl, RbNO 3 and Rb 2 SO 4 by Chrysanthemum morifolium Ramat. cv. Giant No. 4 Indianapolis White was greatest at pH 2, at which there was considerable leaf damage, but changed little at pH 3-10. Absorption of RbCl was greater than RbNO 3 or Rb 2 SO 4 regardless of pH. Absorption of Rb and phosphate as Rb phosphate was minimal at pH 3-6, but was greatly increased at pH 7-10. These results may be explained by the degree of drying and crystallization of the applied compounds on the leaf surface.
