In 2004-2005, winter wheat and spring barley field trials were founded in order to monitor the impact of different levels of defoliation (leaf area reduction) on the grain quality. The defoliation was carried out by the means of mechanical removal of plant parts in the early growth stages. Selected qualitative parameters were determined in the harvested grain. No statistically significant influence of the leaf area reduction on TGW was found in any of the studied crops. The leaf area reduction in barley did not affect the grain's protein and starch content, grain over sieve 2.5 mm, and extract in the grain. The leaf area reduction had a statistically significant influence on the quality of the wheat grain - after reduction the falling number increased statistically significantly (by 29-39 s) and SDS test values decreased (by 8-9 ml).
