Specific Leaf Area and Dry Matter Content Estimate Thickness in Laminar Leaves [PDF]

Annals of Botany, 2005
Leaf thickness plays an important role in leaf and plant functioning, and relates to a species' strategy of resource acquisition and use. As such, it has been widely used for screening purposes in crop science and community ecology. However, since its measurement is not straightforward, a number of estimates have been proposed.

Effect of perforated foil and polypropylene fibre covers on assimilation leaf area of early potato cultivars

Plant, Soil and Environment, 2007
This paper presents the results of a three-year research on the effect of perforated polyethylene foil and polypropylene fibre covering at various lengths of plant cover period (2 and 3 weeks after plant emergence) on the assimilation leaf area of early ...

Specific leaf area responses to environmental gradients through space and time [PDF]

Ecology, 2014
Plant communities can respond to environmental changes by altering their species composition and by individuals (within species) adjusting their physiology. These responses can be captured by measuring key functional traits among and within species along important environmental gradients. Some anthropogenic changes (such as fertilizer runoff) are known

Zero‐sum allocational strategies determine the allometry of specific leaf area [PDF]

American Journal of Botany, 2010
• Premise of the study: Specific leaf area (SLA) is a critical component of the leaf economics spectrum, and many functional leaf traits have been empirically demonstrated to covary with SLA. However, a complete understanding of how change in leaf size influences SLA has not yet emerged.• Methods: To help develop a more complete understanding of the ...

Leaf Area Index Specification for Use in Mesoscale Weather Prediction Systems [PDF]

Monthly Weather Review, 2009
Abstract The energy budget at the surface is strongly influenced by the presence of vegetation, which alters the partitioning of thermal energy between sensible and latent heat fluxes. Despite its relevance, numerical weather prediction (NWP) systems often use only two parameters to describe the vegetation cover: the fractional area of ...

Estimation of leaf area index and assessment of its allometric equations in oak forests: Northern Zagros, Iran

Journal of Forest Science, 2012
The focus of the present study is the estimation of leaf area index (LAI) and the assessment of allometric equations for predicting the leaf area of Lebanon oaks (Quercus libani Oliv.) in Iran's northern Zagros forests.

Leaf area index from litter collection: impact of specific leaf area variability within a beech stand

Canadian Journal of Remote Sensing, 2003
Litter fall collection is a direct method widely used to estimate leaf area index (LAI) in broad-leaved forest stands. Indirect measurements using radiation transmittance and gap fraction theory are often compared and calibrated against litter fall, which is considered as a reference method, but few studies address the question of litter specific leaf ...
