Retrieval of Leaf Area Index (LAI) and Soil Water Content (WC) Using Hyperspectral Remote Sensing under Controlled Glass House Conditions for Spring Barley and Sugar Beet [PDF]

, 2010
Leaf area index (LAI) and water content (WC) in the root zone are two major hydro-meteorological parameters that exhibit a dominant control on water, energy and carbon fluxes, and are therefore important for any regional eco-hydrological or ...

Prediction of leaf water potential and relative water content using terahertz radiation spectroscopy [PDF]

Plant Direct, 2020
AbstractIncreases in the frequency and severity of droughts across many regions worldwide necessitate an improved capacity to determine the water status of plants at organ, whole plant, canopy, and regional scales. Noninvasive methods have most potential for simultaneously improving basic water relations research and ground‐, flight‐, and space‐based ...

MITIGATION OF EXCESSIVE SOLAR RADIATION AND WATER STRESS ON ‘KEITT’ MANGO Mangifera indica TREES THROUGH SHADING

Acta Scientiarum Polonorum: Hortorum Cultus, 2021
Excessive solar radiation “global warming” and water scarcity are consider the main environmental constraints for plant growth and production under arid and semi-arid regions. The current research was aimed to study the effect of irrigation levels (100%,

Prototyping a Generic Algorithm for Crop Parameter Retrieval across the Season Using Radiative Transfer Model Inversion and Sentinel-2 Satellite Observations

Remote Sensing, 2021
In this study, Sentinel-2 data were used for the retrieval of three key biophysical parameters of crops: leaf area index (LAI), leaf chlorophyll content (LCC), and leaf water content (LWC) for dominant crop types in the Czech Republic, including winter ...

Changes of Leaf Water Content in the "Saline" Crops

Japanese Journal of Crop Science, 1959
Determination of leaf water content was made on the "Saline"crops, using rice, wheat, barley and naked barley, grown in sand culture. The saline cultures were done by the solution to which NaCl had been added so as to become the critical concentration for their growth.
