Plant physiological indices
Chlorophyll, flavonols and anthocyanins content in leaves and fruits
Multiplex has been designed for plant compounds measurement. In fact, excitation and emission wavelenghts have been choosen in order to calculate some plant physiological indices.
In other words, based on the raw fluorescence signals, Multiplex calculates plant physiological indices like chlorophyll, flavonols, anthocyanins. It could be really useful for abiotic stress studies, but also fruit maturity and quality.
Multiplex also provide NBIs which is known as a good indicator of plant nitrogen statut.
Specificity of Multiplex 330 : blue fluorescing compounds measurement
The Multiplex can be declined in a specific version named Multiplex 330.
In the Multiplex 330 the UV LED excitation at 365 nm is replaced by a specific one at 335 nm. This allows the Multiplex to detect some specific blue fluorescing compounds in addition to chlorophyll and anthocyanins.
For example the blue fluorescence signal is a good indicator of phytoalexins content in grapevine leaf (resveratrol content), induced by downy mildew on grapevine.
Flashing with Multiplex doesn’t cause any damage to the material measured.
Fast and simple
One measurement takes less than 1 second.
Multiplex is not sensitive to ambient light so you can use it in lab, in greenhouse or in the field.
Moreover, its processor and its internal memory as well as its real-time display make it totally autonomous (no computer is required).
Multiplex has 3 configurations (to avoid low signal or saturation) and 3 diaphragms (area of measurement) so it can be adapted to the sample.
Multiplex is mainly used in Plant Sciences research (physiology, agronomy, ecology, …). For example, Multiplex is used for biotic and abiotic stress studies (light, nitrogen, temperature, salinity…), fruit and food quality.
