Other claims from this paper (15)
- Observation Taxus mucilage peaked in late winter and early spring and was lowest in summer.
- Observation Thuja mucilage peaked in winter and declined through spring to summer.
- Observation Taxus mucilage was found in mesophyll cell vacuoles.
- Observation Thuja mucilage was found in mucilage idioblasts.
- Observation Mucilage storage was independent of temperature.
- Observation Taxus mucilage contained five named sugars and less than 5% uronic acid.
- Observation The peptidic component varied annually from 6% to 15% of mucilage.
- Observation Sugar components varied mainly during spring mucilage synthesis.
- Method / resource Purified Taxus mucilage could not be separated by gel chromatography.
- Observation All mucilage fractions showed similar sugar and peptide composition.
- Observation The authors inferred that Taxus mucilage is a proteoglycan and perhaps similar polymers.
- Observation Dried mucilage equilibrated to 180% at 96% relative humidity.
- Observation Dried mucilage equilibrated to 280-300% at 100% relative humidity.
- Observation Vacuole mucilage concentration was estimated above 5-6%.
- Mechanism The authors suggested water binding stabilizes needle water relations and increases frost resistance.
