Water permeability of Betula periderm
Planta, 1980The 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.

New concepts and terminology of coniferous periderms: necrophylactic and exophylactic periderms
Canadian Journal of Botany, 1973Field 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.

A quick microtechnique for inspection of potato periderm or wound periderm formation
Potato Research, 1973A 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.

THE PERIDERM DEVELOPMENT IN QUERCUS SUBER
IAWA Journal, 2004In 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.

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 ...

Collagen-like Structures in Ordovician Graptolite Periderm
Nature, 1972Electron microscopic studies of skeletal periderm of 450 million year old graptolites (Hemichordata) reveal a morphologically well-preserved fibrous material which resembles collagen in association with polysaccharide. The cortical fibrils, organized into lamellar plies, show a rough periodicity, a central “core” and helical structure, all of which can

The Fine Structure of Graptolite Periderm
1985Graptolites 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 ...

Anthocyanin synthesis in native and wound periderms of potato
Physiologia Plantarum, 2014Skin color of red potatoes is due to accumulation of anthocyanins in the tuber periderm, a protective tissue that replaces the epidermis at an early stage of tuber development. The periderm consists of external layers of suberized phellem cells making up the skin, and internal layers of parenchyma‐like phelloderm cells. Red pigmentation is an important
