Abstract

Seeds of three winter wheat bread cultivars (Triticum aestivum L.): Sadovo 1, Sadovo 772 and Katya, and three durum wheat cultivars (Triticum durum Desf): Progress, Vazhod and Beloslava were used. The accessions have been submitted to sorbtion drying to low moisture content (water activity aw = 0,116). No essential changes were observed in the initial seedling growth. In evaluation of peroxidase isozyme spectra of seedlings no significant changes were detected as a result of sorption drying to low seed moisture and subsequent storage at -18оС. Field evaluation of the main structural plant yield elements uncovered no statistically significant unfavorable effects on the regeneration capacity of wheat seeds as a result of drying (water activity aw = 0,116) and cool storage (-18oC).
