Hodnocení vybraných pomologických a fenologických znaků v hybridním sadu meruněk
Růžička, Matěj
The purpose of this bachelory thesis was to evaluated phenological and pomological characters of apricot hybrids. Observation of phenophases was realized on experimental field Mendel University in Lednice, assessing and measuring of fruit traits was done in a pomological laboratory. The reason for breeding of new hybrids in our conditions is mainly resistance to Plum pox virus and targeted late flowering. Very interesting was the hybrid H. 1103 (tree no. 8), which complied the required parameters. Furthermore, the hybrids, which were smaller in weight, but with good results, were: H. 1102 (tree no. 1, 71) and H 1112 (tree no. 1). In the literary part are included history and expansion, growing in Czech Republic and in the world. Also, are included the details of morfology tree and site conditions, description of influential diseases and pests. There are also description of the varieties, that gave rise to the evaluated hybrids and of couruse, breeding. Formula clause:I hereby declare that, this thesis entitled Evaluation of selected pomological and fenological characters in the field of hybrid apricots was written and completed by me. I also declare that all the sources and information used to complete the thesis are included in the list of references. I disagree that the thesis could be made public in accordance with Article 47b of Act No. 111/1998 Coll., Higher Education Institutions and on Amendments and Supplements to Some Other Acts (the Higher Education Act), and in accordance with the current. I recommend postponing the publication of the bachelor / master thesis for a maximum of 3 years. Directive on publishing of the final thesis. I declare that the printed version of the thesis and electronic version of the thesis published in the application of the Final Thesis in the University Information System is identical. I am aware that my thesis is written in accordance to Act. 121/2000 Coll., on Copyright and therefore Mendel University in Brno has the right to conclude licence agreements on the utilization of the thesis as a school work in accordance with Article 60(1) of the Copyright Act. Before concluding a licence agreement on utilization of the work by another person, I will request a written statement from the university that the licence agreement is not in contradiction to legitimate interests of the university, and I will also pay a prospective fee to cover the cost incurred in creating the work to the full amount of such costs.

Hodnocení vybraných znaků perspektivních odrůd broskvoní
Horsáková, Jana
Dissertation work deals with the evaluation of the selected characters of promising peach varieties grown in the genepool collection and pilot testing block. The evaluation took place between year 2011 to 2013. The work can be divided into three thematical units. The first part deals with the health condition, specifically monitoring of the occurrence of European stone fruit yellows phytoplasma (ESFY) and the plum pox virus (PPV). The second part focuses on the physiological events occurring in flower buds (dormancy, microsporogenesis, frost resistance) and the third unit deals with pomological characteristics of varieties and the economic evaluation of varieties which are already introduced in the commercial cultivation. In the literature section the origin and the spread, world production of peaches and the current situation in the Czech Republic are descibed and a chapter about peach breeding is included as well. Further, chapters characterizing dormancy, microsporogenesis and frost hardiness are described in the work. Literature section also includes content substances and health-promoting substances in peach fruit. The last chapter describes the diseases causing economically significant losses in peaches. In the experimental part the incidence and symptoms of phytoplasma ESFY and synergism between PPV and ESFY was evaluated. The effect of the PPV infection on content of the total polyphenols and the antioxidant activity of fruits was investigated. Further, the termination of dormancy, microsporogenesis and frost resistance of flower buds was evaluated. Significant part of work was the pomological evaluation of selected varieties from genepool collection and evaluation of varieties in pilot testing block conditions. The results show that in peach orchards trees infected by phytoplasma ESFY show various symptoms of the disease which depend on host genotype. Synergism between Plum pox virus (PPV) and European stone fruit yellows phytoplasma (ESFY) has not been confirmed. PPV infection results in increased amount of the antioxidant activity and total polyphenols in peach fruits.Varieties can be divided into 3 groups by the term of termination of endogenous dormancy, paticulary, varieties with early termination, varieties with medium termination and varieties with late termination of dormancy. Evaluated varieties differ, either, in duration and date of occurence of phases of microsporogenesis. The process of dormancy and microsporogenesis of individual varieties is different and is influenced by the weather conditions of the year. There are differences in frost resistance between peach varieties. The highest degree of frost hardiness was set by the 'Lesiberian'. Studied peach varieties show differences in pomological, biological and economic characters. From the evaluated group of varieties the promising are 'Venus', 'Fantasia', 'Fidelia', 'Neve' and 'W 14', where the highest assessment had the variety 'Venus'. Based on evaluation of peach varieties grown in commercial orchards the best variety was 'Symphonie', which achieved consistently high yields and is characterized by good health. 'Fidelia' and 'Orion' were chosen as a mediumly suitable varieties for commercial orchards.

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.

Pomological evaluation of peach and nectarine varieties promising from commercial growing point of view
Jababu, Nambe
According FAO data, peach production in Czech Republic has been very low, for the past two decades averages production has been around 2000 tonnes; whilst consumption for the same period keeps growing; like in the case of most fruit. To be able to bridge the gap between production and consumption, and of course to also increase the income of the local producers, this research was carried out to evaluate some selected peach and nectarine cultivars on the Experimental Orchard (Lednice, south Moravia, Czech republic) of the Faculty of Horticulture of The Mendel University, in 2013, to select and recommend cultivars that will suit and boost productivity of the local growers in Czech Republic. 36 cultivars and 24 parameters were evaluated. Traits and parameters for evaluation were chosen according to the Peach Descriptors for Variability (Nitransky, Holubec, 1992). Evaluations, was done with 3fruits randomly selected from each cultivar. Statistical analysis was done with the software Statistica 12 with Tukey HSD test. 8 cultivars were recommended at the end of the experiment.
