I am wondering if anybody out there can help me...
I am designing an experiment on the effects of two different wavelenths
on the germination of Pinus banksiani seeds (Jack pine). I will be
presenting two tones of different wavelengths to 5 and 5 petri dishes
of seeds. The problem is:
how should I set up a control group?
I am thinking along the lines of a plastic shield, but I'm not too sure
if that will suffice.
Any help would be greatly appreciated.
