The dark horizontal lines on Silver birch bark are the lenticels.^[1]

A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants.^[2] It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which are otherwise impermeable to gases. The name lenticel, pronounced with an [s], derives from its lenticular (lens-like) shape.^[3] The shape of lenticels is one of the characters used for tree identification.^[4]

Formation

Lenticel formation usually begins beneath stomatal complexes during primary growth preceding the development of the first periderm. Lenticels are found as raised circular, oval, or elongated areas on stems and roots. As stems and roots mature lenticel development continues in the new periderm (for example, periderm that forms at the bottom of cracks in the bark).

Fruits

Lenticels on apples.

Lenticels are also present on many fruits, quite noticeably on many apples and pears. On European pears, they can serve as an indicator of when to pick the fruit, as light lenticels on immature fruit darken and become brown.^[5] Certain bacterial and fungal infections can penetrate fruits through their lenticels, with susceptibility sometimes increasing with its age.^[6]

Tubers

Lenticels are also present on potato tubers.^[7]
