Abstract
Patterns of silica deposition on the outer epidermal cell walls of Equisclum arvense and E. hycmalc var. affine were examined by means of electron microprobe analysis. Silica is deposited primarily in discrete knobs and rosettes on the epidermal surface in E. arvense and essentially in a uniform pattern on and in the entire outer epidermal cell walls of E. hyemale var. affine. This markedly contrasts with patterns of silica deposition in internodal epidermal cells of Avena saliva (Gramineae) where silica is deposited primarily in cell walls and cell lumina, and to a much lesser extent, on the outer epidermal surface. Semi-quantitative analysis with the electron microprobe shows that in intercalary meristematic cells of E. aruense, silicon is not present in any cells, but that in mature epidermal cells above the intercalary meristem it is present in significant quantities. The study thus suggests that silica deposition must be a very rapid process in Equisclum and Avena.
