Day 3 – getting into the experiments

We started the day with a beautiful morning to be seen from Husö Biological Station’s pier.

After checking the first test feeding assays, we set up the first day, we prepared the first experiment of the course, treating the seagrass Zostera marina with Oligobetaglucan, potentially inducing its chemical defence system towards grazing. In order to test the response of the seagrass to the treatment, PAM measurements were conducted, looking into this plant’s photosynthetic activity.

We learned about the PAM principles and measurements in additional lectures, and by applying the PAM on the seagrass in daily measurements.
