Tracking viral movement in plants by means of chlorophyll fluorescence imaging
Journal of Plant Physiology, 2011Many techniques have been applied to understand viral cell-to-cell movement in host plants, but little progress has been made in understanding viral vascular transport mechanisms. We propose the use of chlorophyll fluorescence imaging techniques, not only to diagnose the viral infection, but also to follow the movement of the virus through the vascular

Confocal Fluorescence Lifetime Imaging of Chlorophyll Molecules in Polymer Matrices
Photochemistry and Photobiology, 1996Abstract—Confocal fluorescence lifetime imaging has been used to establish the microscopic disposition of chlorophyll molecules in polymer matrices. This study provides a direct test of models proposed on the basis of fluorescence measurements on bulk Alms. We show that whereas chlorophyllbmolecules are uniformly distributed in nitrocellulose matrices,

Rosis - An Imaging Spectrometer For Rejiote Sensing Of Chlorophyll Fluorescence
SPIE Proceedings, 1989The "Reflective Optics System Imaging Spectrometer" (ROSIS) is a compact, programmable imaging spetrometer based on a CCD matrix detector array. The instrument has been designed specifically for the monitoring of water color and of natural chlorophyll fluorescence in order to quantitatively derive pigments, suspended matter and yellow substance ...

Fluorescence Imaging of Photosynthetic Activity in Stressed Plants Via Chlorophyll Fluorescence
1998Various stressors such as ozone and highly reactive oxygen species (1O2, O2-, OH, H2O2), air pollution gases (sulfur dioxide, NOX etc.), drought, heat and high-light stress as well as increased levels of UV-radiation will affect the chemical and pigment composition of leaves, their photosynthetic performance and modify their optical and fluorescence ...

Image Instrumentation of Chlorophyll a Fluorescence for Diagnosing Photosynthetic Injury
2002Environmental stress factors such as air pollutants, agricultural chemicals, water deficit, chilling, and UV light can affect the health of plants (Larcher 1995; Kramer and Boyer 1995; Yunus and Iqbal 1996; De Kok and Stulen 1998). The first symptoms to appear are decreases in photosynthesis and growth.

Chlorophyll Fluorescence Imaging of Heavy Metal Treated Plants
1998Chlorophyll fluorescence has been widely applied as a powerful non-invasive technique for in vivo analysis of plant stress (1,2). In vivo heavy metal stress has also been studied by means of chlorophyll fluorescence (3). In the last years a new approach, the two-dimensional image analysis of the fluorescence signal, has been found very promising.

Plant phenotyping using chlorophyll fluorescence and multispectral imaging
2022High-throughput phenotyping methodologies such as chlorophyll fluorescence and multispectral imaging represent tools for non-invasive quantification of plant performance in different environments. These techniques are widely used, from basic ecophysiological studies to applied research in crop breeding programs.
