Title
Observations on the development of the silica cells of the leaf sheath of wheat (Triticum aestivum)
Elizabeth Blackman Canadian Journal of Botany 1969. doi:10.1139/b69-120
Other claims from this paper (10)
- Observation Wheat sheath silica cells occur as unpaired rod shaped cells and cells paired with cork cells.
- Observation Potential silica cells reach mature shape when leaves are fully expanded.
- Observation The nucleus and cytoplasm are suddenly lost from silica cells, leaving them apparently empty.
- Observation Silica appears to accumulate and precipitate after cells become empty.
- Observation Very early silica accumulation was not detectable.
- Observation In aqueous mounts, accumulating silica formed a translucent peripheral mass around vesicular contents.
- Observation Further silica accumulation formed mature glassy bodies containing small vesicles.
- Mechanism The vesicles probably represented remnants of disintegrated cytoplasm.
- Observation Young silica cells did not appear to have low pH levels.
- Method / resource Enzyme localization tests could not distinguish potential silica cells from immediate neighbors.
