Tomato, onion and tobacco seeds have been subjects for study. The seeds were heterogeneous in initial germinating power. When the seeds with lower initial germination were exposed to the millimeter irradiation (MMI) with the wavelength 5,6 mm and strength of power 10mWt/sm2, a significant increase in germination was attained under the initial (2 min) and terminal (8 and 10 min) exposures of this influence. The non-linear resonant character of the curve exposure of irradiation - germination of seed was revealed. Irradiation of seeds with the definite doses (exposures) of MMI in continuous regime of introduction of this factor was more effective than in an interrupted regime. After irradiation of dry and soaked seeds it was revealed that the resonant character of the dose-effect curve was more pronounced in the variant of soaked seeds. Quantitatively the effects were approximately similar. According to the preliminary data, natural chemical regulators moldstim and GA are less effective, as stimulatory factors of seed germination, than MMI. MMI can be recommended for increase of seed viability after their long-term conservation.
