Other claims from this paper (8)
- Method / resource Raman imaging visualized compositional differences in Equisetum cross sections.
- Observation Silica accumulated in knobs and a thin layer below the cuticula.
- Observation Knob spectra showed a broad band below 500 cm(-1) attributed to amorphous silica.
- Observation The knobs were interpreted as nearly pure amorphous hydrated silica.
- Observation No silanol group vibration was detected in the silicified epidermal layer.
- Association Silicified epidermal layer was associated with pectin and hemicelluloses.
- Observation Pectin and hemicelluloses were high in epidermis and outer hypodermal sterome fibers.
- Observation Inner parts of two-layered cells were nearly pure cellulose aligned parallel to the fiber.
