Growing Garlic Roots in Water

  1. One issue we found with this practical is that peak growth (and therefore mitosis) occurs during the time of peak light during the day. It's therefore best to harvest the tips around early afternoon, which is not always when the lesson will be. Preharvesting and preserving in Farmer's solution is the answer.

    Anyone have any interesting staining recipes for this? We find the usual acetic orcein can be somewhat hit and miss.
     
  2. 0.5% toluidine blue at pH4 is what we use for AQA
     
  3. Nice one!:D
