faserkambium

Faserkambium, also known as fiber cambium, is a secondary meristematic tissue found in certain plants, particularly in woody stems and roots. Its primary function is the production of secondary phloem and secondary xylem, contributing to the increase in girth of the plant organ. Unlike vascular cambium, which typically forms continuous cylinders, faserkambium often develops in discrete strands or fascicles, particularly in plants with herbaceous stems that undergo secondary growth.

This tissue is responsible for the formation of fibers, which are long, slender sclerenchyma cells that provide mechanical support to the plant. The secondary phloem produced by faserkambium contains sieve elements, companion cells, phloem parenchyma, and fibers, while the secondary xylem consists of tracheary elements, xylem parenchyma, and fibers. The arrangement and proportion of these cell types can vary, influencing the mechanical properties and overall structure of the plant. Faserkambium's activity is typically seasonal, with greater production occurring during favorable growing conditions. Its presence allows for the development of strong, supportive tissues, enabling plants to reach larger sizes and withstand environmental stresses.
