Abstract
The influence of laser biostimulation on morphological characters decisive on grain yield (plant height, general and productive tillering, ear length, density and number of spikelets per ear, grain number and grain weight per plant, grain number and grain weight per ear and 1000-grain weight) was evaluated in field experiments conducted with spring wheat cultivars (Alkora, Banti, Eta, Helia, Henika, Hera, Igna, Ismena, Jasna, Jota, Opatka, Omega and Sigma) in the years 1992–1998. Three different kinds of laser were applied (ruby, helium-neon and semi-conducting). The results were analysed statistically with the method for two-factor experiment with randomized blocks. It was found, that the pre-sowing laser biostimulation effect depended on a wheat genotype and on a year of the research.
