Photoperiodism is a response that certain plants have to decreases or increases in the amount they receive in a day (which is normally produced by seasonal movement of the su â¦ n-longer and shorter days).  Some plants require short days to initiate flower formation, while others long day length initiates flowering.
The photoreceptor involved in this response-phototropin-absorbs blue light, but no other wavelength of light. Winslow Briggs tested the Cholodny-Went hypothesis. Briggs removed the tip of grass coleoptiles, divided the tips with a thin piece of mica, and measured the levels of auxin on the sunny and shady sides.
