In 1932, a research group headed by Borthwick and Hendricks showed that red light (630 to 680 nm) elicits the germination of lettuce seeds, whereas far-red light (710 to 740 nm) inhibits the process.
It was further observed that when lettuce seeds were exposed to alternating red and far-red light, almost all seeds that received red light as the final treatment germinated, whereas the seeds receiving far-red light as the final treatment did not germinate.
