rezervparenkimák

Rezvparenkimák are specialized parenchyma cells found in the bark of woody plants. Their primary role is storage, particularly of carbohydrates such as starch, as well as lipids and tannins. These cells are typically thin-walled and can accumulate significant reserves during favorable growing seasons, which are then mobilized to support regrowth or metabolic activities during less favorable periods, such as winter or drought.

The arrangement and morphology of rezvparenkimák can vary between species and plant tissues. They are often found in radial rows within the bark, forming a storage tissue that can be accessed by other parts of the plant. In some cases, these cells may also play a role in defense against pathogens or herbivores due to the presence of tannins. The term "rezvparenkimák" is of Hungarian origin, translating roughly to "reserve parenchyma." Understanding the function of rezvparenkimák is important for comprehending the overall physiology and resource management of trees and other woody species, contributing to their survival and productivity.
