Other claims from this paper (8)
- Observation The primary cuticle appears to form rapidly on the walls of any living cell exposed to air.
- Observation Surface wax is present on the mature leaves of about half of the 50 or 60 species studied.
- Observation In young leaves wax is extruded at random through the newly formed cuticle and accumulates in reticulate to semicrystalline patterns.
- Observation Wax accumulations on older leaves are generally subcuticular and may involve the entire epidermal wall.
- Association Isolated cuticular membranes from Hedera helix increased slightly in permeability to water with leaf age.
- Association Permeability of Hedera helix cuticular membranes to 2,4-D decreased 50 times with leaf age.
- Observation Enlargement of the outer surface of epidermal cells of leaves occurs at the margins of the surface, so earlier formed cuticle and wax are undisturbed.
- Observation Primary walls of angiosperm cells appear formed in specific localized growth regions rather than by plastic extension and apposition.
