ESTIMATES OF THE LEAF AREA INDEX (LAI) USING LAI-2000 AND HEMISPHERICAL PHOTOS IN Eucalyptus PLANTATIONS

open access: yesCiência Florestal, 2014
The objective of this study was to estimate the Leaf Area Index (LAI) by indirect methods in plantations of Eucalyptus clones in two distinct physical-climatic sites, during the dry and rainy periods.

Estimating leaf area index and coverage of dominant vegetation on an extensive green roof in Syracuse, NY

open access: yesNature-Based Solutions, 2023
Roofs with full or partial coverage of vegetation, also known as green roofs, are perceived to restore ecosystem services in urban areas. Research investigations have been carried out to evaluate green roof performance on reducing stormwater runoff ...

Sentinel Image to Estimate Industrial Tomato Leaf Area Index

open access: yesBrazilian Archives of Biology and Technology, 2023
The Leaf Area Index (LAI) is one of the main physiological parameters of the plant related to transpiration, productivity and rainfall interception. Among the methods to determine the LAI, the use of remote sensing that estimates the LAI through image ...

Comparison of LiDAR-based Models for True Leaf Area Index and Effective Leaf Area Index Estimation in Young Beech Forests

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2020
The leaf area index (LAI) is one of the most common leaf area and canopy structure quantifiers. Direct LAI measurement and determination of canopy characteristics in larger areas is unrealistic due to the large number of measurements required to create ...

Retrieval and validation of vertical LAI profile derived from airborne and spaceborne LiDAR data at a deciduous needleleaf forest site

open access: yesGIScience & Remote Sensing, 2023
Leaf area index (LAI) is defined as one half of the total green leaf area per unit ground surface area. Its vertical profile is critical for understanding the remote sensing radiative transfer processes.

Defoliation intensity and leaf area index recovery in defoliated swards: implications for forage accumulation

open access: yesScientia Agricola, 2020
: This study evaluated the leaf area index (LAI) recovery mechanisms and forage accumulation rates on the regrowth of different grass species subjected to different defoliation intensities. For that purpose, plots of Pennisetum clandestinum (kikuyugrass),

Estimate of leaf area index in an old-growth mixed broadleaved-Korean pine forest in northeastern China. [PDF]

open access: yesPLoS ONE, 2012
Leaf area index (LAI) is an important variable in the study of forest ecosystem processes, but very few studies are designed to monitor LAI and the seasonal variability in a mixed forest using non-destructive sampling. In this study, first, true LAI from

Aerial high-throughput phenotyping of peanut leaf area index and lateral growth

open access: yesScientific Reports, 2021
Leaf area index (LAI) is the ratio of the total one-sided leaf area to the ground area, whereas lateral growth (LG) is the measure of canopy expansion. They are indicators for light capture, plant growth, and yield.

Leaf area index estimation using top-of-canopy airborne RGB images

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Leaf Area Index (LAI) is one of the most important biophysical properties of a crop, used in detecting long-term water stress, estimating biomass, and identifying crop growth stage.
