A b s t r a c t. The objective of the study was to determine the effect of different doses of laser radiation on spring wheat grain in early phases of growing. The analysed objects were control seeds and wheat seeds treated with 6 doses of laser radiation. The investigated material com-prised 10 cultivars of spring wheat germinative energy and capacity were evaluated and coleoptile and roots length were measured. The results were analysed statistically. It was found that the laser doses increased germinative energy and germination capacity. Significant differences among cultivars were found for coleoptile and root length too.
