The two nodes of the national FIRI NaPPI complement each other in their ability to measure many structural and physiological parameters of samples by either high throughput or high precision methods.
The UHEL NaPPI facilities consists of motorised plant transportation and maintenance, such as weighing and watering, in combination with imaging tools for RGB, thermoluminescense and chlorophyll fluorescence. These tools allow comprehensive analysis of plant growth and physiology. Specifications of the instruments.

The UEF node consists of versatile instrumentation that has high spatial and spectral resolution with an exceptionally wide wavelength range (250 - 5000 nm). The high precision equipment includes several state-of-the-art imaging instruments, some of which are unique and rare in the plant research community.
Spectral images have tens or hundreds of color channels instead of the traditional three in RGB photographs. These allow detection of spectral properties such as relectance, transmittance and fluorescence that can be linked to chemical composition and structural information of plants that is analysed by traditional measurements in metabolomics laboratory. Thus, spectral imaging techniques provide quantifiable information about chemical or structural characteristics of plants without injuring or even touching the sample. Thus, repeatable gathering of information allows, for example, monitoring of stress symtoms. Symptoms of stress, such as drought, pathogen infection or nutrient deficiencies, can be detected much earlier by spectral imaging than by human eye.
