Biophysical methods for disinfection and stimulation of wheat seeds

In this paper we are shown results of applying electron treatment (disinfection of seed by electrons), and RIES method (electromagnetic seed stimulation). Four cultivars of wheat were used in this trial: Renesansa, Durumko, NS-Rana 5 and Sonata. Seed was treated with fast electrons and just before sowing stimulated by ultra low frequency electromagnetic field (from 0 to 100 Hz). For seed disinfection was used chemical treatment as well, as control variant. Control variant for all treatments was seed without any disinfection. The highest number of spikelets per spike was obtained at variant H+RIES. The highest spike length was obtained at variants e sup(-) + RIES and control. At variant H+RIES was achieved the highest grain number. Treatment H had influence on decreasing of grain mass per spike in relation to control variant, for significant value of 0.15 g. The highest grain mass per spike was obtained at variant e sup(-) + RIES
