- Observation Carnation petal senescence coincided with a decrease in the per-flower yield of cell wall and ethanol-insoluble solids.
- Observation The decrease in cell wall yield was due largely to a loss of neutral sugars.
- Observation Galactose was lost from carnation petal cell walls, with a 45% share of the neutral-sugar loss.
- Observation Arabinose was lost from carnation petal cell walls, with a 23% share of the neutral-sugar loss.
- Observation Water- and chelator-soluble pectins increased per flower throughout carnation petal development.
- Observation Water-soluble pectins made up 18% of total pectin in senescent carnation petals.
- Observation Chelator-soluble pectins made up 58% of total pectin in senescent carnation petals.
- Observation Alkali-soluble pectins were 35 to 45% of total pectin and decreased during senescence.
- Observation Gel chromatography showed no change in the molecular size of chelator- and alkali-soluble pectins in carnation petals.
- Observation Large-molecular-size hemicelluloses decreased during carnation petal development.
- Observation Large hemicellulosic polymers of carnation petals showed a decrease in xylose and galactose content.
