Estimulation of Stem Growth from Wheat Seeds (Triticum Aestivum L.) Using 660 nm Laser Radiation

Abstract

The principal objective is to study the biostimulation effects caused by a semiconductor laser with low level laser radiation with λ = 660 nm on wheat seeds (Triticum Aestivum L). Seeds were treated before sowing with this laser light source. An increase in the growth of the stem of 12% with respect to control seeds was registered for seeds radiated with a power density of 15mW/cm2 and an irradiation time of 60 seconds.
