Led induced chlorophyll fluorescence transient imager for measurements of health and stress status of whole plants [PDF]

open access: yes, 2011
We have developed LED (light emitting diode) induced fluorescence transient imaging instrumentation to image the plant health/stress status by calculation of two images: Fv/Fm (variable fluorescence over saturation level of fluorescence) and the time ...

Models and measurements of energy-dependent quenching. [PDF]

open access: yes, 2013
Energy-dependent quenching (qE) in photosystem II (PSII) is a pH-dependent response that enables plants to regulate light harvesting in response to rapid fluctuations in light intensity.

Pre-Harvest light intensity affects shelf-Life of fresh-cut lettuce [PDF]

open access: yes, 2010
The industry of fresh-cut produce is continuously growing due to increasing demand for fresh, healthy and convenient foods. However, processing of vegetables accelerates quality deterioration due to structural, physiological and biochemical changes ...

Changes in microphytobenthos fluorescence over a tidal cycle: implications for sampling designs [PDF]

open access: yes, 2013
Intertidal microphytobenthos (MPB) are important primary producers and provide food for herbivores in soft sediments and on rocky shores. Methods of measuring MPB biomass that do not depend on the time of collection relative to the time of day or tidal ...
