Photoperiodism in Plants.
TLDR
Ways of finding the pigment and explanations of some of the features of seasonal response are described, including blue or a bluish-green protein that exists in two forms interconvertible by light. Expand
A Reversible Photoreaction Controlling Seed Germination.

DETECTION, ASSAY, AND PRELIMINARY PURIFICATION OF THE PIGMENT CONTROLLING PHOTORESPONSIVE DEVELOPMENT OF PLANTS.
TLDR
The presence of the photoreversible pigment in intact tissue has been demonstrated with a recording, single-beam spectrophotometer and the system response is sufficiently reproducible that valid difference spectra can be obtained by subtracting one recorded curve from another. Expand
The Reaction Controlling Floral Initiation.
TLDR
The equivalence of the control for the size of a pea leaf, after it has developed somewhat in darkness and then is exposed briefly to light, is established with the control of floral initiation in soybean and in barley plants. Expand
ACTTON SPECTRA OF PHYTOCHROME IN VITRO *
Summary First‐order rate constants, Kλ, for the photochemical conversions of both forms of phytochrome, PR and PFR, were measured at various wavelengths between 300 and 800 nm. The product of theExpand
Action of Light on Lettuce-Seed Germination
TLDR
The observations of Flint and McAlister that imbibed seed of some lettuce varieties can be promoted in germination by irradiation in the red portion of the spectrum and inhibited in the infrared were verified and the action spectrum for lettuce-seed germination is the same as that effective for photoperiodic control of floral initiation.
