Wednesday's are long days in the lab, starting with a water change and photosynthesis measurements for my seagrass. The clips attached to the seagrass blades are dark adapting a very small circle of blade tissue (for about 15 minutes) before the sensor is placed over the clips, the clip opened and the measurement taken. The higher the number (on a scale of 0-1), the better the overall health of the blade tissue. So far, after 3+ weeks in the lab, the shoots seem to mostly be holding their own and have more or less remained in the range of 0.8), despite the two different experimental treatments. Only one more measurement to take next week before the experiment ends and statistics begin....
