Spatial vegetation patterns and neighborhood competition among woody plants in an East African savanna [PDF]
, 2017 The majority of research on savanna vegetation dynamics has focused on the coexistence of woody and herbaceous vegetation. Interactions among woody plants in savannas are relatively poorly understood.

Nonstructural Carbon in Woody Plants [PDF]
Annual Review of Plant Biology, 2014 Nonstructural carbon (NSC) provides the carbon and energy for plant growth and survival. In woody plants, fundamental questions about NSC remain unresolved: Is NSC storage an active or passive process? Do older NSC reserves remain accessible to the plant? How is NSC depletion related to mortality risk?

Biological Sciences in Space, 2000 In this review, we attempted to summarize the effect of gravity on growth of woody plants, broad leaved trees, on earth. It is well known that in tilted broad leaved trees, tension wood formed in the secondary xylem causes negative gravitropism. Gibberellin has been shown to induce tension wood in weeping branch, causing its upright growth.

On BC-Subtrees in Multi-Fan and Multi-Wheel Graphs
Mathematics, 2020 The BC-subtree (a subtree in which any two leaves are at even distance apart) number index is the total number of non-empty BC-subtrees of a graph, and is defined as a counting-based topological index that incorporates the leaf distance constraint.

Understanding plant responses to drought: how important is woody tissue photosynthesis? [PDF]
, 2013 Within trees, it is known that a part of the respired CO2 is assimilated in chlorophyll-containing stem and branch tissues. However, the role of this woody tissue photosynthesis in tree functioning remains unclear, in particular under drought stress ...
