      Hello guys,
      Sorry if the title of the topic is not so clear, but I tried my best to clarify what I need in the title so maybe someone interested might help me 🙂

      Okay guys, this is my first topic here, and I wish I find a good answer as soon as possible 😉

      My professor asked us a question and I need to answer it since it will raise my mark :p
      Anyway, the question is that "When we treat stock plants of (Phaseolus aureus) with gibberellins and let them grow in LOW light intensity, that will stimulate adventitious root formation (ARF) in cuttings gotten from those stock plants; while it will inhibit ARF in cuttings gotten from stock plants which were treated with gibberellins too but let them grow in HIGH light intensity"
      Why is that happening? or what is the effect of those different light intensities?

      I appreciate any respond 🙂

      Best Regards,
      Ahmed

      Thanks JackBean for the fast reply
      Actually I just read the abstract that I linked above, and it looks like what I mean..

      And about your links, I downloaded the first one and I’ll read it back home..
      The second one is dealing with SHOOT formation not root..

      Isn’t there a quick answer? since I have to give the answer to my professor tomorrow 🙁

      Thank you a lot JackBean .. Have a happy day 🙂

      I see now, it’s shoot formation on roots :o)

      Mainly, it seems, that the GAs are not that important for the question, but the light is crucial.
