2023/4/20
High-quality genetic maps play important roles in QTL mapping and molecular markerassisted breeding. Tea leaves are not only important vegetative organs but are also theorgan for harvest with importan...
Basal internode elongation of rice as affected by light intensity and leaf area
Internode elongation Leaf area index Light intensity Light quality R/FR
2023/4/21
Short basal internodes are important for lodging resistance of rice (Oryza sativa L.). Several canopy indices affect the elongation of basal internodes, but uncertainty as to the key factors determini...
LEAF AREA INDEX RETRIEVED FROM THERMAL HYPERSPECTRAL DATA
Thermal Emissivity spectra Leaf area index (LAI) Canopy Remote sensing Spectrometer
2016/11/23
Leaf area index (LAI) is an important essential biodiversity variable due to its role in many terrestrial ecosystem processes such as evapotranspiration, energy balance, and gas exchanges as well as p...
Estimation of leaf area index using an angular vegetation index based on in situ measurements and CHRIS/PROBA data
Multi-angular data LAI vegetation index Remote sensing
2016/11/23
The Normalized Difference Vegetation Index (NDVI) is widely used for Leaf Area Index (LAI) estimation. It is well documented that the NDVI is extremely subject to the saturation problem when LAI reach...
ESTIMATING VERTICAL LEAF AREA DENSITY PROFILES OF TREE CANOPIES USING THREE-DIMENSIONAL PORTABLE LIDAR IMAGING
Broad leaf Canopy Leaf area density Lidar Point cloud 3D Voxel
2016/2/29
In this paper, a new method for estimation of vertical leaf area density (LAD) profile of tree canopy using portable scanning lidar is
proposed. In this method, which we refer to as the voxel-based ...
ESTIMATION OF LEAF AREA INDEX AND CHLOROPHYLL FOR A MEDITERRANEAN GRASSLAND USING HYPERSPECTRAL DATA
Hyperspectral Vegetation Estimation Leaf Area Index Chlorophyll
2015/12/31
The study shows that leaf area index (LAI) and canopy chlorophyll content can be mapped in a heterogeneous Mediterranean grassland from canopy spectral reflectance measurements. Canopy spectral measur...
LEAF AREA INDEX ESTIMATION IN VINEYARDS FROM UAV HYPERSPECTRAL DATA,2D IMAGE MOSAICS AND 3D CANOPY SURFACE MODELS
Precision agriculture biomass crop narrow band indices
2015/9/10
The indirect estimation of leaf area index (LAI) in large spatial scales is crucial for several environmental and agricultural applications. To this end, in this paper, we compare and evaluate LAI est...
LARGE SEASONAL SWINGS IN LEAF AREA OF AMAZON RAINFORESTS

2015/9/9
Despite early speculation to the contrary, all tropical forests studied to date display
seasonal variations in the presence of new leaves, flowers and fruits. These past
studies were focused on the ...
