Lignin enhances the mechanical strength of plants and enables their intrinsic water transport. Dendrochronological, wood anatomical, and plant physiological evidence now suggests that the degree of lignin deposition is constrained by low temperature. Placing these findings in an ecological context implies rethinking of the global treeline position.
木质素增强了植物的机械强度,并使它们能够进行内在的水分运输。树木年代学、木材解剖学和植物生理学的证据表明,木质素的沉积程度受到低温的限制。将这些发现置于生态背景下,意味着需要重新思考全球树线的位置。
