Abstract:
Abstract— A rapid transient increase in the growth rate of Cucumis sativus L. seedlings is found to occur after a transition from fluorescent white light to darkness. The post‐illumination burst of growth starts after about 20 min of darkness and lasts for 30 to 50 min. The response occurs after long periods of continuous white light, in cycles of white light and darkness, whether the cotyledons are covered or exposed. The post‐illumination burst is an expression of the loss of photocontrol of hypocotyl inhibition via the specific blue light photoreceptor because (a) its kinetics resemble those of recovery from blue‐light inhibition, and (b) it only occurs on transition from a blue‐rich to a blue‐poor light environment.
