Cation Exchange Capacity, Chemical Composition and the Balance of Carboxylic Acids in the Floral Parts of Various Plant Species

Floral and other parts of antirrhinum, fuchsia, daffodil, and maize have been analysed for cation-exchange capacity (CEC), major and trace-element constituents, and carboxylic acids. The two dicot species, but not the monocot species, have a gradient of CEC, Ca, and Ca/K increasing along the style a...

Description
Summary:Floral and other parts of antirrhinum, fuchsia, daffodil, and maize have been analysed for cation-exchange capacity (CEC), major and trace-element constituents, and carboxylic acids. The two dicot species, but not the monocot species, have a gradient of CEC, Ca, and Ca/K increasing along the style and into the ovary. Trace-element levels in anthers and ovaries are often higher than in the adjacent filaments and styles. The floral parts of daffodil, with the exception of ovary, ovary wall, and anthers, have closely related K/Ca and citric/malic acid ratios which are comparable with those for the rest of the plant.
