Abstrakt

A variety of different physical methods are used increasingly frequently to improve the quality of the
seeds material. Numerous publications confirm the positive effect of, for example, the magnetic field with
a frequency of 50 Hz on the germination of seeds. However, there are no significant reports regarding the
impact of NIR radiation on the growth and development of plants. To fill this gap the influence of three doses
of near-infrared seeds stimulation was tested under laboratory conditions. The power density was 6.9mW/
cm2. The used seeds encompassed four parsley varieties: Konika, Osborne, Alba and Hanácká. Both the influence
of the used variety as well as the radiation dose on parsley germination were tested. The obtained results
indicate that the stimulation affects the selected parsley varieties.
