Abstract
The studied material consisted of 10 cultivars of spring wheat: Alkora, Banti, Eta, Henika, Hera, Igna, Ismena, Jota, Omega and Sigma. Two irradiation methods (laser He–Ne light, power 15 mW) were used. Tests of germination energy, germination capacity, quantitative characters of seedlings: root, coleoptile and first leaf length, were evaluated under laboratory conditions, on control and irradiated materials. Fresh and dry weight of roots and first leafs were also determined. The results of experiments were analysed statistically, Duncan test was applied in order to form homogeneous groups. Significant increase in germination energy and germination capacity was observed only for materials stored for several years and characterized by low values of these parameters. For other seedling characters, different responses to the applied methods and irradiation doses were observed.
