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?
