The development of hyperspectral remote sensing equipment, in recent years, has provided
plant protection professionals with a new mechanism for assessing the phytosanitary state of …

The dynamics of pigment concentrations are diagnostic of a range of plant physiological
properties and processes. This paper appraises the developing technologies and analytical …

We have characterized a new commercial chlorophyll (Chl) and flavonoid (Flav) meter
called Dualex 4 Scientific (Dx4). We compared this device to two other Chl meters, the SPAD …

Life on Earth depends on photosynthesis. Photosynthetic systems evolved early in Earth
history and have been stable for 2.5 billion years, providing prima facie evidence for the …

Methods for chlorosis detection and physiological condition monitoring in Vitis vinifera L.
through accurate chlorophyll a and b content (Cab) estimation at leaf and canopy levels are …

An experiment was conducted under outdoor pot-culture conditions to determine effects of
nitrogen (N) deficiency on sorghum growth, physiology, and leaf hyperspectral reflectance …

Organic fresh products are appreciated and are gaining a good reputation regarding human
health and environmental concerns. Despite the fact that hydroponics are commonly used in …

Chlorophyll a+ b (Ca+ b) and carotenoids (Cx+ c) are leaf pigments associated with
photosynthesis, participation in light harvesting and energy transfer, quenching and …

Varying the spatial distribution of applied nitrogen (N) fertilizer to match demand in crops
has been shown to increase profits in Australia. Better matching the timing of N inputs to …

Precision agriculture requires high-resolution information to enable greater precision in the
management of inputs to production. Actionable information about crop and field status must …
