Examples

“It will be seen that light⟳ at one phase of the rhythm promoted flowering, and at the other phase inhibited it; thus there was a distinct manifestation of photophil and skotophil phases.”

“Short-day effects were seen to result⟳ when light⟳ was restricted to the photophil, while long-day effects were produced when light⟳ encroached into scotophil (figure⟳ 1.2).”

“He postulated that light⟳ falling on the plant⟳ in the scotophil phase would inhibit flowering, and in the photophil phase, enhance flower production.”
