Cinnamon Cork cambium, also known as phellogen, is a type of lateral meristem found in the stems and roots of woody plants, including trees and shrubs. The term “cork” refers to the outer protective tissue that it produces. Cinnamon, a popular spice derived from the bark of certain trees, involves the activity of cork cambium in its formation.

Cork cambium is a layer of actively dividing cells that forms in the bark of the cinnamon tree (Cinnamomum spp.). This specialized meristematic tissue is responsible for producing cork cells, which make up the outer bark. Cork cambium undergoes rapid cell division, generating cells both towards the outside (cork cells) and towards the inside (phelloderm cells). Cork cells eventually become the protective outermost layer of the bark, while phelloderm cells contribute to the inner layers of the bark.

As the cork cambium continues to divide, the newly formed cork cells mature and accumulate substances like suberin, a fatty material. Suberin makes the cork cells impermeable to water and resistant to decay, enhancing the protective properties of the bark. The cells produced towards the inside differentiate into phelloderm, a layer of living parenchyma cells that provide support and aid in the growth and maintenance of the bark.

The cork cells, now formed and mature, gradually accumulate and compress the previous layers of cork and phelloderm, creating the distinctive outer bark of the cinnamon tree. This bark is harvested for its aromatic properties and used as cinnamon. Harvesting cinnamon involves carefully removing the outer bark from the tree. This process ensures that the inner bark, which contains the aromatic

Cork cambium in cinnamon production plays a crucial role in the formation of the protective outer bark, allowing for the harvest of cinnamon while preserving the tree’s health and structure.

The Economic Importance and Uses of Cinnamon Cork cambium

Cinnamon, derived from the bark of trees belonging to the genus Cinnamomum, is a widely used spice and medicinal plant. The cork cambium of cinnamon trees plays a crucial role in the production and extraction of cinnamon.
