Water permeability of Betula periderm

Planta, 1980
The water permeability of periderm membranes stripped from mature trees of Betula pendula Roth was investigated. The diffusion of water was studied using the system water/membrane/water, and transpiration was measured using the system water/membrane/water vapor.

A quick microtechnique for inspection of potato periderm or wound periderm formation

Potato Research, 1973
A method for a quick inspection of wound periderm formation is described. Sections are freehand cut into a stain solution, and microscopic examination is accomplished with an epiplanatic lens.

Wax and suberin development of native and wound periderm of potato (Solanum tuberosum L.) and its relation to peridermal transpiration

Planta, 2004
Native and wound periderm was isolated enzymatically from potato (Solanum tuberosum L. cv. Desirée) tubers at different time intervals between 0 days up to 4 weeks after harvesting. Wound periderm formation was induced by carefully removing native periderm from freshly harvested tubers before storage. The chemical composition of lipids (waxes) obtained

New concepts and terminology of coniferous periderms: necrophylactic and exophylactic periderms

Canadian Journal of Botany, 1973
Field observations were made on wound and pathological periderms, regardless of the causal agent, and periderms formed at abscission zones, old resin blisters and rhytidomes in Abies amabilis (Dougl.) Forbes, Abies grandis (Dougl.) Lindl., Tsuga heterophylla (Raf.) Sarg., and Thuja plicata Donn.

The Periderm of Certain Members of the Cucurbitaceae

The Southwestern Naturalist, 1963
Arising from the phellogen in both the perennial stems and the large storage roots of C. foetidissima, C. digitata, C. palmata and Apodanthera undu- lata is a comparatively thick periderm consisting of a partially suberized phellem and an unsuberized phelloderm.

Microstructure and composition of the periderm of conulariids

Journal of Paleontology, 2016
AbstractTransmitted light and scanning electron imaging of sectioned specimens ofConulariaandParaconularia, prepared using HCl etching and critical point drying, revealed that their periderm is composed of extremely thin (approximately 0.5–3 µm), variably distinct microlamellae that are alternately organic poor and organic rich.

THE PERIDERM DEVELOPMENT IN QUERCUS SUBER

IAWA Journal, 2004
In the cork oak (Quercus suber L.), the phellogen differentiates during the first year of growth in the cell layer immediately under the epidermis and divides to form 3–6 suberized phellem cells. Division of the phellogen only occurs after suberization of the previous divided cell.

The Fine Structure of Graptolite Periderm

1985
Graptolites were marine colonial animals that lived in the benthos about 500 million years ago. From them planktonic automobile forms evolved, inheriting the fibrous periderm of their sessile ancestors. The great age of the fossilized periderm makes a chemical diagnosis impossible, and a transverse banding with a 70 nm periodicity (Crowther and ...

Wound-Periderm Formation

2008
Herbivores, and particularly chewing insects, cause substantial damage to the plant. In addition to lost tissue, there are great concerns of pathogen invasion and water loss at the site of the attack. One of the plant’s defense strategies is the formation of wound periderm at the boundaries of the invaded or damaged region to isolate it from non ...
