Response of spring wheat genotypes to stress influences of laser radiation. Pt. 2. Field experiment

The objective of the research was to determine the effect of 2 methods (D and R) and 6 laser doses treatment on 10 genotypes of spring wheat: Alkora, Banti, Eta, Henika, Hera, Igna, Jota, KOC-239(Ismena), Omega and Sigma. Randomized blocks method with the use of point sowing was applied in the conditions of 2-factor field experiment. In a research next character were analysed: plant height, total and productive tillering, ear length, ear density, number of spikelets per ear, grain number and grain weight per plant, grain number and grain weight per ear and 1000 grain weight. The results of the experiment, which were analysed statistically, have shown significant differences among cultivars and the dose interaction with such morphological characters as the number of spikelets per ear, ear length and ear density
