Stanovení bílkovin u pšenic z konvenčního a ekologického pěstování a jejich vliv na kvalitu zrna
Sedláčková, Anna
The main aim of this diploma thesis was to determine selected signs of baking quality in selected trials from organic and organic agriculture of wheat (Triticum aestivum L.) in the season of 2020/2021. This annual trial included combination of twenty varieties and new breedings of wheat sown in two different locations, Weikendorf (organic agriculture) and Dörfles (ecological agriculture). There was evaluated ifestation by Blumeria graminis, Septoria tritici, Puccinia striiformis and Fusarium graminearum during the 2021 vegetation. Subsequently was determined the yield from individual trials (dt.ha-1) and laboratory analyzes were carried out, starting with the evaluation of flour yield using Quadrumat Junior and SRC-CHOPIN 2, NIR, SDS and Zeleny sedimentation test, alveographic and extensographic evaluation, and finally evaluation using GlutoPeak. The year 2020/2021 was characterised by frequent and high rainfall totals during sowing and harvesting. Meteorological conditions during the year, local influences and different agrotechnical procedures played a significant role in the formation of technological quality of the grain. The limit of 12,5 % of protein set by Austria was met at the location Weikendorf (conventional agriculture) by all varieties and new breeding except variety `Campesino`. At the location Dörfles (organic agriculture) was this limit not met by any of chosen varieties and new breedings. The results of determining the other technological parameters showed significant differences between the quality of the harvest in favor of conventional agriculture. It was made a series of correlations between selected quality parameters. In particular, that grain from conventional and organic farming can differ significantly even from the point of view of evaluating the relationships between selected quality parameters.
