Seasonal Dynamics of Periderm Maintenance and Phellogen Re-Initiation in Aesculus hippocastanum
ForestsThe periderm plays a crucial role in trees, acting as a barrier protecting internal tissues against biotic and abiotic stresses, thus having an impact on tree physiology, ecology, and general performance. It consists of the meristematic phellogen, whose activity gives rise to suberized phellem (cork) cells outwardly and the parenchymatous phelloderm ...

Formation of the primary protective layer and phellogen after leaf abscission in peach
Canadian Journal of Botany, 1985 Potted peach trees (Prunus persica (L.) Batsch cv. Loring) were mechanically defoliated and the influence of temperature on formation of the primary protective layer and phellogen generation in the leaf abscission region was examined histologically.

Summary We analyze the oldest fossil occurrences of wound‐response periderm to characterize the development of wound responses in early tracheophytes. The origin of periderm production by a cambium (phellogen), an innovation with key roles in protection of inner plant tissues, is poorly explored; understanding periderm development in early ...

Ontogeny of Periderm and Phellogen Activity in Ceratonia siliqua L.
Botanical Gazette, 1977In the shoots of Ceratonia siliqua, except for the hypocotyl and the first internode, a continuous superficial phellogen and complete cork cover are established only after a prolonged period of growth has elapsed. The initiation of sequent periderms is restricted to tree parts estimated to be more than 40 yr old.

Initiation of first and successive phellogens occurs mostly in phloem parenchyma or in its derivatives. Species in which shoot phellogen is initiated in the epidermis are the exceptions. However, even in such species, root phellogen is formed in the pericycle.

An Endodermal Phellogen in the Stem of Paederia foetida Linn
Nature, 1945DURING the course of an anatomical study of Pœderia fœtida, a twining shrub of these parts, belonging to the family Rubiaceae, we found that the phellogen originates in the stem, not in the subepidermal layers of the cortex as in most dicotyledons, but in the endodermis.

Sites of First Phellogen Initiation in Conifers
IAWA Journal, 1989Sites of first phellogen initiation were studied in ten species of Pinaceae and Cupressaceae. The distance from the apex, age and the tissue from which the first phellogen is initiated, were determined. In Pinaceae the first phellogen arises at a shorter distance from the apex than in Cupressaceae.
