Monitoring the photosynthetic activity at single-cell level in Haematococcus lacustris

Photosynthetica, 2023
Haematococcus lacustris is an important species of green algae because it produces the high-value carotenoid astaxanthin. Astaxanthin production is enhanced by various stress conditions causing the transformation of green vegetative cells to red cells ...

Enhanced fluorescence imaging in chlorophyll-suppressed tobacco tissues using virus-induced gene silencing of the phytoene desaturase gene

BioTechniques, 2010
Fluorescence imaging in plants is unusually challenging because of the large amounts of photosynthetic pigments contained in green plant tissues. For example, chlorophyll can obstruct the penetration of light and has high levels of autofluorescence at ...

Evaluation of chicory seeds maturity by chlorophyll fluorescence imaging [PDF]

Biosystems Engineering, 2011
Chicory (Cichorium intybus L.) seed production includes sorting to remove foreign materials and non-viable seeds. A machine vision system was developed to monitor the fluorescence in order to detect the immature chicory seeds. It comprised a monochromatic light source, a highpass filter and a monochromatic CCD camera sensitive to red and infrared. With

Development of an Automated Low-Cost Multispectral Imaging System to Quantify Canopy Size and Pigmentation

Sensors
Canopy imaging offers a non-destructive, efficient way to objectively measure canopy size, detect stress symptoms, and assess pigment concentrations. While it is faster and easier than traditional destructive methods, manual image analysis, including ...
