Abstract:
The effect of monochromatic coherent light with a wavelength of 635 and 405nm, which was generated by LED lasers with a power of 100mW, was studied to assess growth parameters of some species of Poaceae family plants (Triticum aestivum L., Avena sativa L., Zea mays L.), was. It was found that the germination readiness and germination ability of the investigated plants were likely to increase only with the combined action of red and blue light for 10 sec. Growth parameters of plants significantly increased (10.4-124, 5%) by depending on the dose and spectral composition of the irradiation. The most effective is red light and complex radiation for 10 seconds. The content of chlorophyll a and chlorophyll b is probably influenced by the complex (red and blue light) laser irradiation of seeds.
