The Inhibition of Cell Division in the Mesocotyl of Etiolated Oat Plants by Light of Different Frequencies

Cell division taking place in the nodal meristem of etiolated oat (Avena sativa cultivar Victory) seedlings is shown to be almost uniformly sensitive to different wavebands of light in the visible spectrum. The significance of the observations in relation to the identity of the photoreceptor, and to...

Description
Summary:Cell division taking place in the nodal meristem of etiolated oat (Avena sativa cultivar Victory) seedlings is shown to be almost uniformly sensitive to different wavebands of light in the visible spectrum. The significance of the observations in relation to the identity of the photoreceptor, and to the opinion that green light is ‘morphogenetically inactive’ is discussed.
