18 kwi 2013 · Summary. 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.

Parallel venation is found in monocots, and pinnate and palmate venation is common in eudicots. The maidenhair tree, ginkgo (Ginkgo biloba), has a unique venation pattern in which each vein divides into two similar parts. This is known as dichotomous venation (Figure \(\PageIndex{12}\)).
summarize the strikingly diverse current applications of leaf vein research in multiple fields of science and industry. A unified core understanding will enable an increasing range of plant biologists to incorporate leaf venation into their research. I. Introduction Within and across species, leaves are enormously diverse in
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.
Monocots have parallel venation; the veins run in straight lines across the length of the leaf without converging at a point. In dicots, however, the veins of the leaf have a net-like appearance, forming a pattern known as reticulate venation.
2 lut 2023 · 1. Parallel Veins. They commonly run parallel to each other throughout the length of the leaf. Less typically, parallel veins also run laterally from the leaf’s midrib to the leaf edge. Parallel veins are found in monocot plants such as rice, corn, corn, lilies, and grass.
18 kwi 2013 · Using sections proportionate to leaf size is useful to compare venation of leaves that vary due to dimorphism. We discuss protocol strategies for imaging of difficult leaves for venation...
