Effects of stomatal density and leaf water content on the ¹⁸O enrichment of leaf water.
The New phytologist, 2016Leaf water isotopic composition is imprinted in several biomarkers of interest and it is imperative that we understand the isotopic enrichment of leaf water. Here, we test the effect of stomatal density and leaf water content on the oxygen isotopic composition of leaf water in transgenic Arabidopsis plants expressing different stomatal densities, and ...

CANOPY AND LEAF LIGHT REFLECTANCE FEATURES IN RELATION TO WATER CONTENT IN APPLE
Acta Horticulturae, 2004The relationship between spectral light reflectance and leaf water content has been established for several species, giving a sound basis to the use of remote sensing technologies in water stress detection for natural vegetation and crops. Nevertheless, few data are available about fruit tree species.

Remote sensing of leaf water content in the near infrared
Remote Sensing of Environment, 1980Abstract A stochastic leaf radiation model was used to predict leaf spectral reflectance as a function of leaf water content for a dicot leaf. Simulated spectral reflectances were analyzed to quantify reflectance differences between different equivalent water thicknesses.

Mapping of Leaf Water Content Using Near-Infrared Hyperspectral Imaging
Applied Spectroscopy, 2013In this study, near-infrared hyperspectral imaging was applied to predict the water content of golden pothos ( Epipremnum aureum) leaves, after which partial least squares regression (PLSR) analysis was performed to predict their averaged water content.

Temperature effects in determinations of leaf relative water content
Grass and Forage Science, 1977AbstractDifferences between field temperature and floating temperature during determination offect apparent leof relative water content (RWC). When floating temperature was lower or higher than field temperature, RWC appeared higher or lower, respectively, than when the temperatures were the same.

Convolutional Neural Network based Regression for Leaf Water Content Estimation
2019 Second International Conference on Latest trends in Electrical Engineering and Computing Technologies (INTELLECT), 2019With the advancements in precision farming, crop sensing is gaining importance for timely crop health management. Leaf water content (LWC) is key component to determine vegetation health and nourishment. Timely estimation of LWC could save us from hazardous damage by pre-planning: drought stress on plants, irrigation and prediction of woodland fire ...

Spectroscopic determination of leaf water content using continuous wavelet analysis
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010Abstract The gravimetric water content (GWC, %), a commonly used measure of leaf water content, describes the ratio of water to dry matter for each individual leaf. To date, the relationship between spectral reflectance and GWC in leaves is poorly understood due to the confounding effects of unpredictably varying water and dry matter ratios on ...

SPIE Proceedings, 2011
Leaf and canopy water contents provide information for leaf area index, vegetation biomass, and wildfire fuel moisture content. Hyperspectral retrievals of leaf and canopy water content are determined from the relationship of spectral reflectance and the specific absorption coefficient of water over the wavelength range of a water absorption feature.
