In “Kórniczanin”, issue no. 11/2026, on page 14, an article entitled “Why Does Pine Need Sugar?” was published as part of the series “News from the Kórnik Gardens”. The author of the text is Dr Roma Żytkowiak from the Institute of Dendrology, Polish Academy of Sciences.
The article discusses the role of sugars in the functioning of Scots pine — one of the most important tree species in Polish forests. Carbohydrates produced in the needles during photosynthesis are not only a source of energy for the tree. They are involved in the development of shoots, roots and needles, wood formation, storage of reserves, and the maintenance of tissue vitality.
The importance of sugars becomes particularly evident under environmental stress. In winter, they help protect cells from freezing, while during drought they support the maintenance of water balance. As a result, they influence not only the growth of pine, but also its ability to survive changing seasonal conditions.
The text presents pine as a dynamic organism that constantly manages its resources. Sugar transformations connect photosynthesis with tissue formation, reserve storage, and the tree’s resistance to stress.
