title: Field control of plant growth and development through the laser activation of phytochrome.
abstract: Helium-neon lasers emitting at 632.8 nm can influence the phytochrome controlled growth and development of plants more than a quarter of a mile away. It may therefore be possible to control the growth of crops using lasers to activate the phytochrome system.
