18 de abr. de 2013 · The design and function of leaf venation are important to plant performance, with key implications for the distribution and productivity of ecosystems, and applications in paleobiology, agriculture and technology. We synthesize classical concepts and the recent literature on a wide range of aspects of leaf venation.
20 de sept. de 2014 · Here, we examined both costs and benefits to redundancy in 339 individual reticulate leaf networks comprising over 3.5 million vein segments. We compared levels of costs and benefits within reticulate networks to those within analogous networks without loops known as Maximum Spanning Trees (MSTs).
1 de may. de 2001 · The leaves of extant terrestrial plants show highly diverse and elaborate patterns of leaf venation. One fundamental feature of many leaf venation patterns, especially in the case of angiosperm leaves, is the presence of anastomoses.
6 de nov. de 2018 · We analyzed the venation of temperate dicotyledonous species from different taxonomic groups and chose 18 woody and 12 herbaceous species that have reticulated leaf venation.
We synthesize classical concepts and the recent literature on a wide range of aspects of leaf venation. We describe 10 major structural features that contribute to multiple key functions, and scale up to leaf and plant performance.
The less prominent (minor) veins of a leaf may form a branching, netlike pattern, which is called reticulate venation (Figure \(\PageIndex{14}\)). In contrast, the minor veins are arranged neatly, forming a ladderlike structure in percurrent venation.
In eudicots, the branching pattern seen as the veins further divide into smaller veins resembles a net, so it is called reticulate (netted) venation. Figure \(\PageIndex{7}\): Types of leaf venation: A) Pinnate venation, B) Parallel venation, and C) Palmate venation.
