Abstract
The biological effect of two-frequency laser pulsed radiation produced on copper vapor during pre-sowing treatment of rice seeds of Veles and Leader varieties at early stages of development in extreme stressful environmental conditions has been studied. The copper vapor laser used in the experiment had the following output characteristics: wavelengths of 510.6 nm (green radiation line) and 578.2 nm (yellow radiation line), pulse duration of 15 ns, repetition frequency of 10 kHz, total pulse power of 10 kW, energy-power ratio between the green and yellow radiation lines 3/1 The interaction of laser radiation with wavelengths of 510.6 and 578.2 nm in the nonlinear medium of the seed caused the formation of additional wavelengths: a total wavelength of 271 nm (ultraviolet radiation) and a difference wavelength of 4.37 microns. Exposure to each of the four wavelengths in its spectral range could lead to the initiation of at least four radiation-induced biochemical reactions. It is shown that pre-sowing treatment of rice seeds with two-frequency laser pulsed radiation for 5–20 seconds had a stimulating effect on the growth and development of rice (the greatest effect was when exposed to 5–10 seconds), and also increased its stability when grown in extreme stressful environmental conditions (moisture deficiency, depleted soil) at early stages of development.
