Green plants (fennel, parsley, salad, spinach, celery etc.) play the unique role in maintenance of a vitality of a human body. One of the reasons of low consumption of green plants by the population of Krasnoyarsk Region during winter period is their high cost. One kilogram of fennel or other green plants costs in the shop 350 rubles and more. This price in many respects depends on the price of seeds. The purpose of scientific work was the re-search of influence of presowing treatment regimes of superhigh-frequency (UHF) fennel seeds and parsley in their laboratory viability to decrease in norm of seeds seeding. The temperature of heating of seeds depends on humidity of seeds, the intensi-ty of field in material and exposition. It is the major factor making the stimulating impact on seeds. The technique of active planning of two-factorial exper-iment according to the plan of Kohn is the basis for the researches. As a result of carrying out laborato-ry tests on the research of influence of the modes of preseeding processing of seeds of green cul-tures with UHF energy on their viability in vitro re-vealed the modes which promote the best germina-tion of seeds. The seeds of fennel and parsley ac-quired in retail trade have viability about 8 %. It was established that at the influence of UHF energy with a specific power of 100 Watts per 1 cubic decimeter during 90 with or respectively 450 Watts per 1 cubic decimeter within 30 seconds it was possible to achieve the increase in viability up to 25 %, thereby to reduce three times the norm of seeds seeding.
