Leaf size and leaf consistence of a riverine forest formation along a climatic gradient
Oecologia, 1978The riverine forest formation on the levees along the Orange River in South Africa shows a shift in floristic composition as the river traverses various climatic zones on its course through the temperate area in the eastern parts of the subcontinent, the central semi-desert region, and the desert area near the Atlantic in the west.

RFLP tagging of QTLs conditioning specific leaf weight and leaf size in soybean
Theoretical and Applied Genetics, 1998Selection for high specific leaf weight (SLW) in soybean [Glycine max (L) Merr.] may increase apparent photosynthetic rate per unit leaf area (AP), which in turn may improve seed yield. In general, the SLW and leaf size are negatively correlated in soybean. To maximize total photosynthetic performance, and perhaps the seed yield, of a soybean cultivar,

The determination of leaf size on the basis of developmental traits
New PhytologistSummary Mature leaf area (LA) is a showcase of diversity – varying enormously within and across species, and associated with the productivity and distribution of plants and ecosystems. Yet, it remains unclear how developmental processes determine variation in LA.

A Leaf-Size Hierarchy of Alternating Rebound Turing Machines
J. Autom. Lang. Comb., 2002This paper continues the investigation of the fundamental properties of alternating rebound Turing machines (ARTMs). In particular, we shall introduce a simple, natural complexity measure for ARTMs, called "leaf-size", and provide a hierarchy of complexity classes based on leaf-size bounded computations.

Herbivory and the evolution of leaf size and shape
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1991Abstract Why do leaves have such varied sizes and shapes? Part of the answer lies in physiological and biomechanical demands imposed by different habitats; selective forces that are now reasonably well understood. In contrast, the im pact of herbivores on the evolution of leaf size and shape has rarely been investigated and is poorly ...

The Control of Leaf and Ear Size in Barley
Journal of Experimental Botany, 1973The relative growth rates, growth rates, and final size of tillers and main-shoot leaves, inter nodes, and ear of a freely tillering spring barley genotype were measured and compared with those of a non-tillering single-gene mutant. Leaf and internode growth and final size were greater in the non-tillering mutant. The differences, it is proposed, arise

Leaf size, climate, and energy balance
Science, 2017Plant Ecology Why does plant leaf size increase at lower latitudes, as exemplified by the evolutionary success of species with very large leaves in the tropics? Wright et al. analyzed leaf data for 7670 plant species, along with climatic data, from 682 sites worldwide.
