IBBR - URT Metaponto
A better understanding of the plant / environment systems may arise through the analysis of phenotypes, allowing the possibility to set up innovative programs for crop protection from viruses, insects and diseases, and to identify varieties with improved performance, greater efficiency in resource use or new traits of agricultural interest.
Phenotyping studies are already in place at the URT, the running projects have as their main purpose:
- To investigate how the interaction with beneficial soil microorganisms (i.e. Trichoderma spp.) influences plant growth, architecture and morphology at the shoot and root level.
- To measure photosynthetic performance under control and stress conditions (research group Tucci-De Palma. Species: Solanum lycopersicum L.).
- To quantify differences in physiological performances under drought and salt stress conditions of mutants and traditional landraces. (research group: STRESS Lab, Grillo-Costa-Batelli. Species: Solanum lycopersicum L.).
- To evaluate growth, geometry profile and physiological status of mutants for epigenetic regulators during development. (research group Conicella-Consiglio-Termolino. Species: Solanum lycopersicum L.).

Phenotype screening by image analysis of a mutant tomato compared with the isogenic line.
Readings and data in the visible field (RGB)
Non-destructive image analyses were carried out during plants growth, relative to the dimensional index (in pixels, three per plant), color index (in % - four color classes), plants height and compactness. Plant observation takes place laterally (RGB_side) and from above (RGB_TV), and it is possible to acquire images from two different angles (0 and 90 °). The images obtained from different angles allow the acquisition of more informations about morphology, size or biomass of the plants analyzed.
