Growth rate formula for plants
WebOnce the plants have cooled weigh them on a scale. Separate the root from the top (cut at soil line). Separately weigh and record the root and top for each plant. (Dry weight for roots/dry weight for top of plant = root/shoot ratio) The root/shoot ratio can be calculated for each treatment.
