It is a cylindrical tissue that covers the surfaces of stems and roots of perennial plants during early secondary growth; therefore it is not found in monocots and is confined to those gymnosperms and eudicots that show secondary growth. The first periderm most commonly originates immediately below the epidermis, but in some species, it arises deeper in the stem, usually in the primary phloem. In mature plants, the epidermis is replaced by the periderm. At the end of season, however, compact suberized cells are formed, e.g., Tilia, Quercus. A wound periderm was formed 9 days post wounding. The previous years phellogen and derivatives are cut off by the new phellogen, die, and are pushed to the exterior where they accumulate to form the rhytidome.

The ability of the plant to produce phellogen in deeper layers, when the superficial periderm is removed, is utilized in the production of commercial cork (Q. Suber). In some species, the first periderm appears rather deep in the stem, usually in the primary phloem viz., Berberis, and Vitis etc. The periderm is also formed along surfaces exposed after abscission of plant parts, such as leaves or branches. The periderm is a cylindrical tissue that covers the surfaces of stems and roots of perennial plants during early secondary growth; therefore it is not found in monocots and is confined to those gymnosperms and eudicots that show secondary growth. In addition, we highlight recent advances in our understanding of how suberization may be regulated, including at the phytohormone, transcription factor, and protein scaffold levels. The periderm is the layer of the bark that is exposed to the environment. It also evolves as protective layer near injured parts (wound periderm). (c): Tunica corpus theory is connected with shoot apex. The former occurs when subsequent periderms exist in restricted overlapping strata, each cutting out scale of tissue, e.g., Finns and Pyrus etc. This site needs JavaScript to work properly.
