Predicting red cypress vine leaf area by a linear equation [PDF]
We aimed to determine a linear equation to predict the leaf area of Ipomoea quamoclit L. (red cypress vine), an important weed infesting perennial crops in Brazil and worldwide, as a function of leaf blade length and width.

Vein‐to‐blade ratio is an allometric indicator of leaf size and plasticity [PDF]
PremiseAs a leaf expands, its shape dynamically changes. Previously, we documented an allometric relationship between vein and blade area in grapevine leaves. Larger leaves have a smaller ratio of primary and secondary vein area relative to blade area compared to smaller leaves.

Influence of blade aerodynamic model on the prediction of helicopter high-frequency airloads [PDF]
Brown’s vorticity transport model has been used to investigate the influence of the blade aerodynamic model on the accuracy with which the high-frequency airloads associated with helicopter blade–vortex interactions can be predicted.

Leaf blade area estimate of Digitaria pentzii under different cutting heights
Pasture studies require information on leaf area, as it is one of the main parameters for evaluation of plant growth. Thus, the objective of this study was to estimate the leaf blade area of pangolão grass (Digitaria pentzii Stent.) using non-destructive

Genome-wide analysis of spatiotemporal expression patterns during rice leaf development
Background Rice leaves consist of three distinct regions along a proximal-distal axis, namely the leaf blade, sheath, and blade-sheath boundary region. Each region has a unique morphology and function, but the genetic programs underlying the development ...
