ibkid123 Posted December 11, 2013 Report Share Posted December 11, 2013 Hello guys,The topic for my IA is: Investigate an abiotic factor that effects either rate of seed germination or rate of plant growth.I thought of several topics, but a new one I thought of is how the wavelength of light affects the rate of plant growth. How would I alter the rate of plant growth? Would I just use a filter?Thank you. Reply Link to post Share on other sites More sharing options...
