Germination of rapeseed under continuous led lighting in the modes of low-energy photon fluxes of monochromatic radiation

In order to study the effect of low-energy monochrome radiation on the germination of rapeseed of the new variety Antares, the authors used light-emitting diodes of blue (440 nm), green (525 nm), red (660 nm) and far red (730 nm) light, as well as those of UV-A radiation (380 nm) with an intensity of 0.367-6.904 µmol/m2* s on different spectra. Different types of monochrome radiation affected the germination of seeds and the growth of sprouts in different ways. According to the indicators of germination energy, seed germination, weight of 100 sprouts, and yield of green mass, the best results were obtained when germinating using the green light. Based on experimental data, the patent was issued for the invention “The activation method of rapeseed germination under monospectral illumination”. Irradiation of seeds with the monochrome far-red light significantly reduced the germination ability and yield of sprouts.
