How will a longer vegetative season affect carbon sequestration in plant biomass
Kasperová, Denisa ; Albrechtová, Jana (advisor) ; Ponert, Jan (referee)
As a result of human activity, a large number of greenhouse gases, especially CO2, is released into the atmosphere, which causes a greater greenhouse effect and an increase in the temperature of the surface of the planet and the air in the atmosphere. Ongoing climate change is one of the great challenges facing society, as rising temperatures on the planet greatly affect the functioning of its ecosystems. Extremes arising from climate change, especially temperature rise and lack of precipitation or a change in the annual distribution of precipitation, affect the physiology and phenology of plants. Higher temperatures cause plant growing seasons to shift and lengthen, which has a direct impact on the sequestration of carbon in plant biomass through a biochemical, physiological plant process called photosynthesis. The increase in CO2 concentration in the atmosphere is slowed down by terrestrial forest ecosystems, as they can retain carbon in their tissues, especially in wood, for a relatively long time before it returns to the atmosphere. However, the efficiency of binding carbon into biomass also depends on other physiological processes, e.g., photorespiration, breathing, gas exchange between the plant and the atmosphere. Stressors caused by climate change can then limit growth, photosynthesis,...

Hodnocení výnosových prvků lineárních a hybridních odrůd pšenice ozimé (Triticum aestivum)
ŠÍR, Josef
This diploma thesis is focused on the subject of winter wheat, specifically on the field of its use, agrotechnical requirements, growth phases, fertilization, weeds in its growth and the creation of economic yield. The aim of the work is to compare the yield elements of selected linear and hybrid varieties of winter wheat. For this purpose, an attempt was set up on the school farm of secondary school of agricul-ture in Tábor with the linear varieties Chiron, Atuan, Ascaban, Pirueta and the hy-brid varieties Hyking, Hybiza, Hyvento, Hydrock, Sofru, when during the vegeta-tion time was determined and evaluated seed density, the number of ears before harvest, the number of grains in an ear and the grain yield achieved.

Současné trendy a výsledky pěstování Slunečnice roční (Helianthus annuus L.)
Spousta, Jakub
In the master thesis is evaluated general knowledge about cultivation of Common Sunflower (Helianthus annuus L.). The theoretical part is based on observation of Sunflower cultivation technology in particular company in 2016 with focus on Sunflowers species. The Sunflower was grown at 20 % of total companys farmland area (1384,78 ha). There was grown following Sunflower species in the benchmark year: medium early hybrid NK Neoma CL, early hybrid NK Brio and medium early hybrid LG 56.55. The Iregi species has been added for the analysis in which phenological phases of the species were studied. Samples to determine the quality parameters were collected at the harvest. Identificated values of laboratory analyzes were statistically processed and evaluated. Last but not least was calculated cost profitability within the financial materials of the company.

Hodnocení růstových a sklizňových údajů netradičního ovocného druhu - dřínu obecného
Shromáždil, Filip
This thesis examines the growth and harvesting characteristics of the non-traditional fruit species of dogwood. The work in the explanatory section deals with the origin of this fruit shrub, its distribution, the demands it makes on the environment, its growth properties and propagation technology. Then it describes the chemical composition of the fruit and possibilities for using it in the food industry or in horticulture. The selection of six dogwood species (´Elegant´, ´Fruchtal´, ´Jolico´, ´Lukjanov´, ´Vydubec´ and ´Vyshegorod´) was evaluated at an experimental area of the breeding institute in Zabcice. For each variety, we examined and compared the extent of the phenological phases, the size of the bush volume, the size of the fruit harvest and both external and internal features of the fruit. This last observation involved evaluation of the length, width and weight of the fruit, the proportions and weight of the stone, plus the levels of vitamin C, dry matter and refractometric dry matter. The results obtained from the measurements were processed and statistically evaluated. Through a combination of our results and reference to expert studies, we are able to recommend the most suitable varieties for cultivation under our climatic conditions.

Hodnocení růstových a sklizňových údajů vybraných odrůd a genotypů dřínu obecného
Hašková, Lenka
The aim of the bachelor thesis was to find out and evaluate the growth and harvesting properties and their subsequent evaluation in the selected group of varieties of Cornus mas L. in the monitored period 2018. The general part deals with the characteristics of Cornus mas L., its history and use. Further is described agrotechnics, expanding, its demands on growing, propagation, planting and harvesting. A selected set of 6 varieties of Cornus mas L., was evaluated on the experimental plot in Žabčice. Phenological phases, growth and harvesting properties were monitored. The information obtained was processed and evaluated. According to the results achieved, the most suitable varieties were recommended for cultivation. Dogwood can be recommended for larger production plantings and further expansion among small.

Hodnocení růstových a sklizňových údajů kamčatských borůvek (Lonicera caeruela L.)
Prnová, Štěpánka
The objective of this thesis is the evaluation of growth and harvest data of sweetberry honeysuckle (Lonicera caerulea L.), furthermore evaluation and comparison of phenological characteristics of different varieties. The phenological phases of the shrubs were evaluated: sprouting, flowering, ripening, harvesting and leaf fall. In terms of growth is evaluated height and cubic volume of shrubs and effective yield. For harvesting parameters was monitored height, width and weight of the fruits, the content of refractive solids, vitamin C and a total solids content in the fruits. Every measurement and evaluation is supplemented by tables and graphs with the results evaluated by program STATISTICA 12. Flowering was evaluated according to photographic evidence taken over several weeks in the main growing season. At the end, the most suitale varieties were recommended according to the findings in the terms of size and weight of fruits, vitamin C and a refractive solids and also taking into account the volume of shrubs and effective yield of a given variety.

Pomologické hodnocení vybraných méně pěstovaných jádrovin
Sikorowská, Monika
This diploma thesis is about some less grown pome fruit species like Rowan, Service Tree, Hawthorn, Medlar, Crataegomespilus Simon-Louis and Sorbopyrus Scheele. Thesis is focused on the observation of individual phenophases for this species and recording of the numbers of flowers and fruits on them. Work is focused mainly on pomological description of mentioned species and variety. Contain statistically processed data about fruit size. In experimental part of the thesis are values for vitamin C content, carotenoids and minerals (K, Na, Ca, Mg) content, which were also valuated statistically. The result outcome of this thesis is chosen species and cultivar for the climate conditions of Czech Republic.

Hodnocení růstových a sklizňových údajů netradičního ovocného druhu - dřínu obecného
Doležálková, Blanka
The aim of this thesis is to find out the growth and harvest features of the chosen set of the cornelian cherry. The summary of history, spread and typical features, that this fruity species distinguished, was given. It describes the chemical structure of fruits, the propagation of cornelian cherry and its cultivation. It also contains its use and processing in chosen products. The assortment of six cultivars ('Elegantní', 'Fruchtal', 'Jolico', 'Lukjanovský', 'Vydubecký', 'Vyšegorodský') was evaluated on the experimental and demonstration area of the institute SŽP Žabčice. The terms of phonological phases, the sizes of bush content, the size of fruity picking, the outer and inner features of fruits were found out. The results of individual measures were processed and statistically evaluated. The acquired values were arranged to charts and graphs and then described in detail in the textual part. The most suitable cultivar for cultivation and succeeding processing is possible to choose according to the acquired values.
