Abstract
The studies were carried out on four cultivars of winter rye: Amilo, Dańkowskie Nowe, Diamant and Warko, two cultivars of spring rye: Abago and Bojko, five cultivars of winter triticale: Fidelio, Grenado, Presto, Woltario and Zorro, and two cultivars of spring triticale: Legalo and Dublet. In laboratory conditions, the effects of different doses of light from a 200 mW semiconductor laser on sowing value, morphological features and diastatic power were evaluated. The triticale cultivars, compared to the rye ones, showed lower sensitivity to pre-sowing radiation of grains. In winter rye forms, significant stimulation by laser radiation of the radicle, coleoptile and first leaf length was found. Higher values of energy and germination capacity as the result of laser treatment were observed in the cultivars of spring rye. Pre-sowing radiation resulted in significant elongation of the first leaf in winter triticale and of the coleoptile in spring triticale. The rye cultivars responded to laser light with an increase in diastatic power in winter forms, and with a decrease in this trait value in spring forms. Significant doses x cultivars interaction was observed in winter triticale, and marked stimulation of diastatic power was recorded with spring triticale forms.
