Diversity of patterns of volatile metabolites in accessions of wild strawberries
Project
Project code: JKI-ÖPV-08-1329
Contract period: 01.09.2015
- 30.11.2017
Purpose of research: Applied research
Volatile metabolites of plants (PVOCs) fulfil a wealth of bio-functions in the ecosystem. For breeders in strawberry fruits the knowledge of PVOC patterns is important regarding sensory quality and resistance traits. The processes of domestication and breeding are combined with changes of metabolite patterns of strawberries which so far occur unconsciously and accidentally. These changes may have consequences for health and enjoyment value as well as for resistance. In comparison to good tasting old cultivars and highly aromatic wild types a so called domestication effect regarding aroma compounds was demonstrated for high yielding cultivars. In plant breeding programmes wild types are increasingly used as donors for sensory traits and resistance. The aim of the project is to investigate the diversity of metabolite patterns in wild species. For profiling GC-MS methods in combination with SBSE (stir bar sorptive extraction) and SPME (solid phase microextraction) will be used.
