Other claims from this paper (9)
- Mechanism Primary cuticle appears to form rapidly on living cell walls exposed to air.
- Observation Surface wax was present on mature leaves of about half the species studied.
- Observation Wax was extruded through young leaf cuticle and accumulated in patterned deposits.
- Observation No wax pores were observed through cuticle or primary wall of mature leaves.
- Observation Wax accumulations on older leaves were generally subcuticular.
- Association Hedera helix cuticular membrane permeability to water increased slightly with leaf age.
- Association Hedera helix cuticular membrane permeability to 2,4-D decreased 50 times with leaf age.
- Mechanism Leaf epidermal outer surfaces appear to enlarge at their margins.
- Mechanism Angiosperm primary walls may form in localized growth regions.
