Leaf relative water content estimated from leaf reflectance and transmittance [PDF]
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016 Remotely sensing the water status of plants and the water content of canopies remain long term goals of remote sensing research [1]. In the research we report here, we used optical polarization techniques to monitor the light reflected from the leaf interior, R, as well as the leaf transmittance, T, as the relative water content (RWC) of corn (Zea mays)

Measuring specific leaf area and water content v1 [PDF]
, 2018 Here we describe the standardised protocol used by the Canadian Airborne Biodiversity Observatory (CABO) to measure leaf water content and specific leaf area, using the WinFOLIA™ software (Régent Instruments). These leaf area and water measurements are done on a subset of leaves from the same bulk leaf sample used to measure leaf spectral reflectance ...

Close-range hyperspectral spectroscopy reveals leaf water content dynamics [PDF]
Remote Sensing of Environment, 2021 Water plays a crucial role in maintaining plant functionality and drives many ecophysiological processes. The distribution of water resources is in a continuous change due to global warming affecting the productivity of ecosystems around the globe, but there is a lack of non-destructive methods capable of continuous monitoring of plant and leaf water ...

Exogenous Nitric Oxide and Silicon Applications Alleviate Water Stress in Apricots
Life, 2022 Many plants confront several environmental stresses including heat, water stress, drought, salinity and high-metal concentrations that are crucial in defining plant productivity at different stages of their life cycle.

Leaf water content and palisade cell size [PDF]
New Phytologist, 2005 Summary The palisade cell sizes in leaves of Eucalyptus pauciflora were estimated in paradermal sections of cryo‐fixed leaves imaged in the cryo‐scanning electron microscope, as a quantity called the cell area fraction (CAF). Cell sizes were measured in detached leaves as a function of leaf water content, in intact leaves in the field during a day"s ...

Leaf Water Content and Hormone Effects on Ribonuclease Activity [PDF]
Plant Physiology, 1973 In barley (Hordeum vulgare) leaves in which the water balance was not hampered, kinetin and abscisic acid effected the well documented decrease and increase, respectively, in RNase activity. When the plants were exposed to water shortage, leaf-water saturation deficit increased steadily, with kinetin enhancing and abscisic acid retarding the rise ...

Leaf nitrogen content estimation using top-of-canopy airborne hyperspectral data
International Journal of Applied Earth Observations and Geoinformation, 2021 Remote estimation of leaf nitrogen content is a critical requirement for precision farm management. Precise knowledge of nitrogen distribution in the crop enables farmers to decide the fertilisation amount required at specific locations on the farm ...

Monitoring leaf water content with THz and sub-THz waves [PDF]
Plant Methods, 2015 Terahertz technology is still an evolving research field that attracts scientists with very different backgrounds working on a wide range of subjects. In the past two decades, it has been demonstrated that terahertz technology can provide a non-invasive tool for measuring and monitoring the water content of leaves and plants. In this paper we intend to
