Effects of clumping on estimates of stand leaf area index using the LI-COR LAI-2000

Canadian Journal of Forest Research, 1993
Eighteen natural second-growth stands of Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) from a wide range of stand densities and stocking levels were measured for stand leaf area index (LAI) from allometric relationships (direct LAI) and the LI-COR LAI-2000 plant canopy analyzer (indirect LAI).

Performance of the LAI-2000 plant canopy analyzer in estimating leaf area index of some Scots pine stands

Tree Physiology, 1994
The LAI-2000 plant canopy analyzer (Li-Cor, Inc., Lincoln, NE) was tested at six experimental plots of Scots pine (Pinus sylvestris L.) in central Sweden at peak leaf area in August and after litterfall in October 1990. An independent estimate of leaf area index for August 1990 was obtained based on an empirically derived regression of needle area on ...

Estimation of Leaf Area Index for Cotton Canopies Using the LI‐COR LAI‐2000 Plant Canopy Analyzer

Agronomy Journal, 1995
AbstractMeasurement of leaf area index (LAI) is useful for understanding cotton (Gossypium hirsutum L.) growth, water use, and canopy light interception. Destructive measurement is time consuming and labor intensive. Our objective was to evaluate sampling procedures using the Li‐Cor (Lincoln, NE) LAI 2000 plant canopy analyzer (PCA) for nondestructive ...

Spatial and Vertical Leaf Area Index of a Deciduous Forest Resolved Using the LAI-2000 Plant Canopy Analyzer

Forest Science, 1996
Abstract The LAI-2000 Plant Canopy Analyzer (LI-COR Inc., Lincoln, Nebraska) was used to determine the spatial and vertical canopy structure of a heterogeneous deciduous forest near Chalk River, Ontario. Overstory vegetation area index (VAI) demonstrated the spatial heterogeneity that exists between points at 10 m spacing and also with ...

A rapid method for estimating leaf area index with the Li-Cor "LAI 2000 PCA" for oil palm [PDF]

, 1996
Une nouvelle méthode d'obtention de l'indice de surface foliaire (LAI) a été comparée, à la station de recherche de Marihat (nord de Sumatra), avec la méthode directe conventionnelle couramment utilisée par le CIRAD-CP. Avec cette méthode directe, le matériel choisi (clonal et issu de semence) a présenté des valeurs de LAI de 3,4 à 7 pour des surfaces ...

Estimation of Leaf Area Index: a case study with LAI-2000

2012
The leaf area index (LAI) is the key for modelling and knowledge of water and carbon cycle, therefore needed for the climate change measurement. This study makes a short review of direct and indirect methods with their advantages and their disadvantages; an overview of the discrepancies about the Licor LAI-2000 Plant Canopy Analyser is performed.
