ABSTRACT
The influence of damaged grain on biological value has been the subject of research for many authors. Until now in most investigations the biological value of damaged grain was estimated during the beginning phases of growth • up to sprouting. It would be interesting to investigate further germ which was grown from grain with different types of damage up to the crop. The point of this paper was to state what the influence of wheat grain damage was on some chosen values of crop structure. The subject for investigation was wheat grain variety Grana. For the experiment 13 types of grain damage were selected. The damaged grain was sowed in soil in a completely randomized scheme. All seedlings were ensured optimum conditions for vegetation by applying the technique of field-crop production. After reaching peak the plants were harvested manually. It was possible to make measurements of certain components of the crop: number of plants, length of ears, height of plants, number of ears, weight of 1 000 grains, number of grains in an ear. The results after statistical analysis showed the influence of each type of damage on the crop structure. The group with the greatest amount of damage was determined.
