Chlorophyll fluorescence imaging of cadmium-treated white cabbage plants

E3S Web of Conferences, 2013
The chlorophyll fluorescence imaging technique is a valuable tool to study the impact of heavy metal stress in plants. The aim of this paper was to investigate the influence of Cd on photosynthetic apparatus of white cabbage (Brassica oleracea subsp ...

Chlorophyll fluorescence imaging of photosynthetic activity with the flash-lamp fluorescence imaging system

Photosynthetica, 2005
A flash-lamp chlorophyll (Chl) fluorescence imaging system (FL-FIS) is described that allows to screen and image the photosynthetic activity of several thousand leaf points (pixels) of intact leaves in a non-destructive way within a few seconds. This includes also the registration of several thousand leaf point images of the four natural fluorescence ...

Microalgae Monitoring in Microscale Photobioreactors via Multivariate Image Analysis

ChemEngineering, 2021
Microscale photobioreactors for microalgae growth represent an interesting technology for fast data production and biomass characterization; however, the small scale poses severe monitoring challenges, as traditional methods cannot be used.

Utilization of fluorescence images in chlorophyll in Cirebon waters, Indonesia

Borneo Journal of Marine Science and Aquaculture (BJoMSA), 2021
Satellite is one of the tools used to detect chlorophyll concentration. MODIS chlorophyll concentrations appears to be disturbed by colored dissolved organic matter (CDOM). The fluorescence approach can represent the chlorophyll concentration near the coast more accurately.

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology

Advanced Materials Technologies, EarlyView.
The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.

Noninvasive Phenotyping of Plant–Pathogen Interaction: Consecutive In Situ Imaging of Fluorescing Pseudomonas syringae, Plant Phenolic Fluorescence, and Chlorophyll Fluorescence in Arabidopsis Leaves

Frontiers in Plant Science, 2019
Plant–pathogen interactions have been widely studied, but mostly from the site of the plant secondary defense. Less is known about the effects of pathogen infection on plant primary metabolism.

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants

Advanced Science, EarlyView.
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...
