Models for Estimating Different Crops Leaf Area Index Using Hyperspectral Data
As a parameter of researching plant groups and cluster analysis, leaf area index (LAI) is closely related to a variety of biological processes, such as transpiration, photosynthesis and respiration. Now LAI has become a key parameter in researching the eco-system. There are two ways to get the LAI data, one is from the ground-based measurement, the other way is based on retrieval from remote se...
متن کاملTopical anti - inflammatory activity of yacon leaf extracts
Smallanthus sonchifolius (Poepp.) H. Rob., Asteraceae, known as yacon, is an herb that is traditionally used for the treatment of diabetes in folk medicine. However, recent studies have demonstrated that this plant has other interesting properties such as anti-microbial and anti-infl ammatory actions. Thus, the purpose of this study was to evaluate the topical anti-infl ammatory property of dif...
متن کاملLeaf Area Index in Earth System Models
The amount of leaves in a plant canopy (measured as leaf area index, LAI) modulates key land–atmosphere interactions, including the exchange of energy, moisture, carbon dioxide (CO 2), and other trace gases, and is therefore an essential variable in predicting terrestrial carbon, water, and energy fluxes. The latest generation of Earth system 5 models (ESMs) simulate LAI, as well as provide pro...
متن کاملDynamics of leaf area for climate and weather models
[1] Leaf area is the most relevant scalar variable for describing the dynamics of vegetation on seasonal time scales, and hence is required as part of the land-surface component of a meteorological model. A mathematical scheme for the dynamic vegetation component of such a model is formulated and reduced to a toy model for seasonal leaf dynamics. Leaf growth is seen as a temperature-initiated i...
متن کاملEmpirical Regression Models for Estimating Multiyear Leaf Area Index of Rice from Several Vegetation Indices at the Field Scale
Leaf area index (LAI) is among the most important variables for monitoring crop growth and estimating grain yield. Previous reports have shown that LAI derived from remote sensing data can be effectively applied in crop growth simulation models for improving the accuracy of grain yield estimation. Therefore, precise estimation of LAI from remote sensing data is expected to be useful for global ...
