Wheat plants with drought stress

In this movie, you can see multiple wheat plants being imaged over time. Multiple indices where measured but in this movie the efficiency of photosynthesis is displayed showing a clear effect of the drought stress in the tip of the leaves.   The plants are perfectly segmented out of the background because we are using chlorophyll fluorescence masking to segment the plant out of the background.

Tomato seedling

This tomato seedling was monitored over a period of 5 days inside our PRO EDEN cabinet, which allows complete control over the growing environment. The cabinet's advanced system enables researchers to track the plant's progress continuously without disrupting the measurements. The imaging area can accommodate up to 80 x 80 centimeters.

Arabidopsis Imaged over time

In this movie, you can see multiple Arabidopsis plants being imaged over time in color. The plants are perfectly segmented out of the background because we are using chlorophyll fluorescence masking to segment the color image. Only plant material has fluoresces, eliminating the need for a blue background. This experiment was conducted at the BTI facility in New York using the automated plant phenotyping system of WPS.

Black nightshade and herbicide

Two droplets of 5 microliter of metribuzin (non-systemic herbicide) are applied to two different leaves of Black Nightshade. Within 6 hours, the effect of the herbicide can be observed in the Fv/Fm image (right side). Even after 70 hours, the interaction of the herbicide and the leaf is not detectable in the colour image (right side). The PlantExplorer can, at an early stage, detect and quantify the effects of the herbicide, which have a strong correlation with the total biomass of the plant after 14 days.

Cabbage and Xanthomonas

This cabbage seedling is exposed to the bacterium Xanthomonas. Via guttation, the bacterium enters the leaf. Within 48 hours, the PlantExplorer shows the presence of the bacterium. Visually (left image), no interaction of bacterium and leaf can be observed. The cotyledons show low photosynthetic efficiency and will not contribute much to the plant’s energy production.

Phytophthora spot inoculation on potato leaf

This example video shows a chlorophyll fluorescence images measured through a petri dish. In this way the disease can be contained but with chlorophyll fluorescence we can also image the leaf.

Phytophthora spot inoculation on potato plant

This example video shows chlorophyll fluorescence images on the top left, colour images top right, calculated Fv/Fm bottom left and calculated area with low Fv/Fm at the bottom right side of a potato leaf. The leaf was spot inoculated with phytophthora spores on the bottom through a single droplet; the images are taken from above through a glass cover. The colour image shows necrosis around the inoculation spot, the Fv/Fm image shows an enlarged damaged area, clearly showing a light blue colour on the bottom.

Potato fungus infection:

These potato leaves are infected with a type of fungus. You can see it spread through the leaves in several hours. With the PlantExplorer, you can automate these measurements and measure in real time.
