Abstract:
This diploma thesis deals with an influence of high temperature and water shortage on the protein content of gliadin and glutenin fractions in four varieties of winter wheat: Bohemia, Tobak, Pannonia and var. Syria with designation S46 (IG142780). The crop was grown at 26, 29, 32, 35, 38 and 41 °C during anthesis under control irrigation treatment (with soil moisture higher than 70 %) or under drought stress (with soil moisture lower than 30 %). To separate gliadins, the A-PAGE method was used, and glutenins were separated by SDS-PAGE method. Proteins were quantified by computer densitometry. Significant influence of genotype on the gluten proteins was found. Variety Pannonia has high content of -, 5-gliadins, LMW and HMW glutenins, but low content of other gliadin fractions. It was the opposite in the other varieties. Due to temperature, as well as drought, there was an increase in the content of all gluten fractions, especially of HMW glutenins, 1,2-gliadins and total gliadins. The largest increase in the gluten fractions due to drought was observed in Syria variety. In other varieties simultaneous exposure to drought and heat caused decrease in gliadin content, but increase in glutenin content. Drought at high temperatures reduced gliadin-to-glutenin ratio, mostly in Bohemia variety. This ratio has increased due to the temperature, especially in Tobak variety. For Syria variety, no effect of stress conditions was found on gliadin-to-glutenin ratio.

Abstract:
This diploma thesis deals with an influence of increasing temperature and water shortage on the content of gliadin proteins in four varieties of wheat: Bohemia, Pannonia, Tobak and RGT Reform. Samples were cultivated at 26, 29, 32, 35, 39 and 41 ° C. Due to the lack of culture samples at 41 ° C, these samples were not used for our experiment. Cultivation took place during flowering with sufficient moisture (with soil moisture higher than 70%) or under drought stress (with humidity below 30%). The A-PAGE method was used to separate gliadin fractions. Quantification was performed by computer densitometry. Significant influence of water availability on gluten protein content was found. The lack of moisture in the stress environment caused a relative increase in gliadin fractions compared to conventional conditions, especially in the Pannonia and RGT Reform varieties. The Pannonia and RGT Reform varieties responded most to the temperature, while Bohemia. The Tobak variety responded to the temperature in interaction with water scarcity. Due to the rising temperature, virtually all gliadin fractions in the Pannonia and RGT Reform varieties increased. The effect of drought often manifests itself in interaction with the influence of temperature. The most dramatic effect was the drought in interaction with temperature in the Tobak variety, where the gliadin content increased. In general, the temperature and drought were most affected by -gliadin fractions of all four varieties of wheat.

Abstract:
In this diploma thesis the impacts of both nitrogen fertilization and drought on the content of proteins of the gliadin fraction in case of a winter wheat variety Tiguan were observed. Selected samples were cultivated at two locations in a total duration of two years. Two different conditions were selected: one without the nitrogen fertilization (0 kg N/ ha) and the other with the nitrogen fertilization in 140 kg N/ ha concentration. Second observed factor was the drought which was ensured by roofs above the crops and their cultivation in common climatic environment. Gliadin fraction was separated by the A-PAGE method and the protein quantification carried out by a computer densitometry. Such nitrogen fertilization caused a significant increase of gliadins, especially -1,2 and -5 fractions. Stress induced by the drought caused an increase of gliadin content compared to the control sample, particularly in case of - and - fractions. The most important factor influencing the gliadin content in grains was therefore the nitrogen fertilization in a dry environment. The observed increase of gliadin content was lower in case of the sample which was fertilized in a humid environment than in case of the sample which was fertilized in the dry one.

Abstract:
The presented work provides the results of experiments with winter wheat during the growing season 2016/2017, which were established at the field research station of Mendel University in Žabčice. Eight winter wheat varieties were grown on two sites with different water regimes in the soil (optimal conditions - Obora/water-limited conditions - Písky). The varieties were evaluated for the number of spikes per area, thousand seed weight and grain number per spike. Then the grain yield per hectare and harvest index (which was calculated as the ratio of biomass and grain) were evaluated. In the water-limited conditions, there was a decrease in all monitored characters. The site had the largest influence on the number of spikes per area where the average number of spikes per area under water-limited conditions fell by 23 %. The second most affected was thousand seed weight which was decreased by 19 %, and the least affected character was grain number per spike, which was changed by 11 %. The harvest index was lower on water-limited field. The weight of biomass was reduced by 24 – 34 % and weight of grain was reduced by 50 % for evaluated varieties. The average yield at the site with optimal conditions was 10,4 t per ha and at water-limited conditions site it was 6,1 t per ha. According to the results of this harvest year 2017 varieties Patras, Gordian and Cimrmanova raná were found as suitable for worse conditions. On the other hand varieties Tobak and Hyfi seem to be unsuitable for stressful conditions.

These days, wild pig, or wild boar, causes considerable damage in the Czech Republic, but also in other countries of almost the whole of Europe. The thesis describes the issues of damage done by the wild pig and the protective measures against this damage. The basis of the thesis was to measure the areas of damaged vegetation of unbearded and bearded varieties of wheat. Damaged areas on individual fields of both varieties were then compared with each other and evaluated. The choice of a variety, as an agro-technological measure against damage done by wild pigs, showed to be very effective. The damages that the wild pig did in unbearded varieties were not done in bearded ones.

Abstract:
This diploma thesis Comparison of yield capacity of spring wheat varieties deals with small-scale experiments of three varieties (Astrid, Epos, Tercie) in two vegetation periods. Repetition variations were established in 2015 and 2016 on the school grounds of the Agricultural Faculty of the University of South Bohemia in České Budějovice. During two growing seasons the production of yield elements (the number of plants and the number of fertile crops - ears) was monitored for all varieties and after harvest other yield elements were evaluated the number of grains in the ear and weight of a thousand grains. Actual revenue was determined. Grain analysis determined the bulk density as a quality indicator. In the results and discussion the individual yield elements are described and statistically evaluated. The number of plants was better in 2015 regarding soil density characteristics. The number of fertile offsprings was the highest in the case of Astrid variety in the first production year (642). The number of grains in the ear was very variable for all observed varieties, both production years 2015 and 2016 (from 15 grains in the ear to 68 grains in the ear). Total actual yield was higher in 2015 than in 2016 (by 1.1 t.ha-1). Each spring wheat is characterized by its shorter growing season, during which it must optimally produce the highest yield possible and therefore needs adequate responsible care.

This thesis was aimed on the elaboration of literature review and a on the practical assessment of the field trial with a mixtures of varieties. The first part of the literature review was devoted to crop diversification in agriculture, which is closely related to mixtures of varieties. In the other part were characterized advantages of mixed varieties, such as better yield of mixed varieties in comparison with component varieties. We have also described some of the mechanisms for the creation of income (and mechanisms against pathogens). Another part was devoted to quality of mixed varieties. The last part was devoted to disadvantages resulting from the cultivation of mixed varieties. In the year 2013 it was founded field trial in Žabčice -- Nova obora, which was investigated in practical part. It was investigated effect of three binary mixtures. These mixtures were identified as : Elan + Golem, Viriato + Tobak Baletka and Annie. Each of pure component varieties were planted for checking and comparison. The main examined factors were yield, weight of thousand seeds, sedimentation index, wet gluten, gluten index, falling number, nitrogenous substances, weight and height of the plant. The best yield reached mixture Elan + Golem (average yield was 9.61 t / ha), it's yield reached the yield of the best variety Elan (9.92 t / ha). The mixture Tobak + Annie had higher average value of the falling number and nitrogenous substances than the pure varieties, average results this mixture reached in values of sedimentation index and wet gluten. In the total evaluation this mixture was recommended as the best one. The holder of the quality in this mixture was the Annie variety. This mixture has fulfilled requirements for baking quality and reached Czech elite level.

The thesis was focused on the evaluation of the health status of winter wheat leaves. The experiments were established in the autumn of 2017 in the terrier area of Veľaty, the district of Trebišov, the county of Košice, in the south - east of Slovakia on my own fields. We tested five line wheat varieties. Evaluation of each experiments was performed three times. The least affected was the Genius type. On the other site the lowest level of fungal pathogen resistance was in the Bertold variety. Probably due to its unstaining. The Bodycek variety also appeared very well, but because it was not regulated by growth, it did not achieve the desired results. In the experimental fields, we focused primarily on the attack of wheat leaves by fungal pathogens that cause severe leaf diseases.

Abstract:
The aim of this thesis is the evaluation of grain yield formation and state of health of the line and hybrid wheat. For this target it was founded a one-year small-land experiment on the land of the Faculty of Agriculture of The University of South Bohemia in České Budějovice in September 2014. The experiment had 16 different variants in four repetitions, where the main factor was the different cultivar - Hybrid Hymack and line Tobak were sown at two different dates (early date 20th September, late date 29th October). In both of sowing dates, cultivars also differed in amount of seed quantity, where for Hymack it was 1,1 and 2,2 MKS/ha and for Tobak it was 3,5 and 4,2 MKS/ha. The last option was the stimulation by using the products from the company EGT and checking. During the vegetation, the number of plants per square meter, number of tillers and number of spikes were monitored and the state of health was evalueted. After the harvest were evalueted the grain yield, volume weight, HTZ and the number of grains per spike. The indicative measurement was made by the N - tester and a Sun Scan. The results achieved during the one-year small-land experiment show, that due to the influence of favorable year and high intensity of cultivation, a line cultivar Tobak achieved a higher yield (10,4 t/ha) compared to hybrid cultivar Hymack (10,4 t/ha) about 7 %. In the evaluated parameters the biggest difference was in HTZ, when Tobak had 47 grams and Hymack had 43,5 grams. This difference was the reason for higher yield of the line cultivar. Both of cultivars have achieved a better yield in the early sowing date and responded positively to the application of the growth stimulators. On the contrary, in the late date of sowing, cultivars reached a higher volume weight of the grain. During the growing season, the hybrid cultivar had better state of health and considerably higher tillering capability and the leaf area. The hybrid wheat's yield potential can be applied especially in unfavorable conditions such as drought or poor quality soil. At high intensity of cultivation supported by suitable climatic conditions, hybrid wheat hasn´t got an economic application in comparison with profitable line cultivars. The reason for this, is the high price of the seed and need for higher doses of nitrogen. The hybrid wheats are suitable for unfavorable growing regions with early sowing.

Abstract:
The main objective of dissertation thesis was to show impact of exogenous application of growth regulators on physiology and the total yield of winter wheat under drought stress. For the purpose of assessing the impact of growth regulators under drought conditions, it was in 2013-2014 and 2014-2015 established field experiment at the field experimental station Žabčice. The field experiment monitored the effects of growth regulators on water use effeciency and tolerance to drought stress. We compared the effect of four growth regulators representing a different mode of action, the application time and potential of drought stress reduction. These were the active compound chlormequate (CCC) applied at the beginning of stem elongation, trinexapac-ethyl applied in the middle of stem elongation, etephon applied at the end of stem elongation and finally it was application of fungicide from the group of strobilurins (azoxystrobin) carried out at the heading growth stage. The drought stress was inducted by using experimental rain-out shelters that were installed at the end of stem elongation. Approximatelly 2 and 4 weeks after the beginning of drought stress, physiological measurements. Lower grain yields were recorded in 2014 with the average yields (4 to 6 t.ha-1). The highest grain yields were in 2015 with the average yields (10 to 13 t.ha-1).The positive impact of plant growth regulators was demonstrated mostly in increased yield and spike productivity. A positive effect of plant growth regulators on elimination of negative impact of drought in the parameter Amax was demonstrated after application of azoxystrobin, to a lesser extent after application of CCC and trinexapax. Etephon had the lowest impact on elimination of drought stress. The negative impact of drought stress on chlorophyll content was statistically significantly eliminated in all treatments by growth regulators. In addition, application of growth regulators reduced the impact of drought stress on water use efficiency (WUE). Growth regulators also mitigate a negative impact of drought stress on the primary phase of photosynthesis evaluated using chlorophyll fluorescence parameters. In the growth chamber experiment, the effect of growth regulators on the combined effect of drought stress and vapour pressure deficit (VPD) was studied. The highest positive effect in dry conditions had application of trinexapac-ethyl and CCC regulators under both low and high VPD.
