Project description:

Recent developments in analysis of plant constituents with spectroscopical methods in the field and in the lab have demonstrated the potential for quick assessment of plant chemical composition, for instance using near infrared spectroscopy (NIR) in the lab,or chlorophyll and flavonoid analysis in the field. This is important because it enables quicker analysis of plant performance after exposure to climatic or environmental stressors. However, some of the methods have been developed for use with specific crop plants, and it is an open question to which extent the field-based spectroscopical methods are useful in analysis of wild plants, for instance with thick or strongly pigmented leaves. We suggest to analyse  leaf chemical constituents as chlorophyll, flavonoids, condensed tannins and nutrients as N and P in a wider range of wild plant species or woody plants, for instance from a Danish forest nature reserve, a bog or a heath, or from the Arboretum in Hørsholm or the Botanical Garden in Copenhagen, using both traditional chemical methods and new spectroscopical methods, and investigate the relationship between the results achieved by the different methods.
