Procedures for Measuring
Height - Height is measured with the bottom edge of the ruler resting on the styrofoam surface of the quad up until the highest point of the plant (but don't let the ruler touch the plant!).
Cotyledon Width - This measurement is taken on ONLY ONE cotyledon. The measurement should be taken from the wider cotyledon for consistency. Please see this picture for a visual example of how to measure Cotyledon Width.
Notes on Measuring Development - Initially we planned to include an additional metric to help quantify the measurement of development. We had intended this metric to be the counting of the number of true leaves visibly discernible when looking down at the plants apex. We realized that this is not a reliable metric because it is highly subjective. Often, it was the case that different investigators would rate a plant as having different numbers of true leaves. As a result, we decided not to use this as a metric.
