The main objective of the proposed research program is to demonstrate physiological integration of trees that are interconnected through root grafts or parental roots (root sprouting species). We recently demonstrated that trees could affect the physiology of their neighbours through root connections, but the level on physiological integration between trees is not known. For example, we do not know to what extent (spatially and quantitatively) C reserves and resources are shared between trees, and in particular, how relationships of competition vs cooperation affect forest dynamics.

拟议的研究计划的主要目标是证明通过根移植或亲本根（根发芽物种）相互连接的树木的生理整合。我们最近证明，树木可以通过根连接影响其邻居的生理，但树木之间的生理整合水平尚不清楚。例如，我们不知道树木之间在多大程度上（空间和数量上）共享碳储量和资源，特别是竞争与合作的关系如何影响森林动态。
