This podcast presents two key sources of research related to tree resilience and photosynthesis measurement. The first source focuses on a study of the resilience of eight tree species to urban environments in Warsaw. By measuring chlorophyll fluorescence and chlorophyll content, scientists identified which species tolerate road proximity stress the best (such as Gleditsia triacanthos and Platanus × hispanica) and which are more vulnerable (Tilia × europaea and Ginkgo biloba). The second source discusses devices used for measuring photosynthesis, explaining their functional principles and applications in plant physiology research. It covers different types of systems (open vs. closed), the calculation of photosynthetic rates, and examples of studies where these instruments have been used.
