I am running an experiment for my class in Biology and I need some help. I have learned that each species of willow trees and plants have a special rooting hormone which allows cut/pruned branches and limbs to produce new roots of its own. Are there methods of extracting these hormones and put them to use? I am trying to take a large sample of small cuttings, add water and bring the water to the point before boiling (about 95 degrees F). If anybody had any tips for me to help me run this experiment, I would greatly appreciate it.
