Možnosti využití antistresových přípravků při pěstování zeleninové sadby

Sijková, Adriana January 2014 (has links)
The teoretical part of the thesis seeks of the zoom and description of plant stress, the possibility of using anti-stress products and their effects on plants. Description of selected vegetable species and the impact date for sowing seed. Practical work is dedicated to monitoring anti-stress effect products, their effects on plants and the effect on the overall structure of plants. After statistical analysis has been evidence for an effect of the individual plant morphological characteristics of plants.

Možnosti využití sušeného granulovaného hnoje a dalších organických hnojiv veškolkařské výrobě

Hartmannová, Jitka January 2008 (has links)
This thesis on the theme Possibilities dried grained dung utilization and other organic dungs in nursery production was elaborated in phase 2006 -- 2008 in The Department of Breeding and Propagation of Horticultural Plants on Mendel University of Agriculture and Forestry in Brno. Using of organic dungs is necessary at rising soil fertility because the main component of these dungs form organic materials of vegetable and animal origin. Their main advantage is their rise and regeneration of humus support and positive action on soil structure, water and air mode in soil. Their disadvantage is their big volume and due to that the recommended doses for plant fortilization are too high. We can use, as alternative this disadvantage in comparision with mineral dungs, grained organic materials. Granules are dried to low volume mass and they have higher content of nutrients. This form facilitates not only their aplication ,but also manipulation with them. The organic dungs are necessary component of fortilization, how it results from cited experiment, not only for their nutrition quality and contnent humus materials, that have specifically effect to plant grow and progress, but also for their ability to give support to better utilization of nutrients from industry dungs. Dosage depends on demands for individual plants. Here is one parameter, that is impossible omit in the first place at containered plants, and that is possible plant damage by lack of water. The producers emphasise importance of watering because water is utilized for dried dungs dissociation. Single-shot utilization of high batch can to cause other damage. We can predate to these dangers by help of automated watering and single batch of dungs partition. Dictum on dungs utilization will always stay on growers.

Study and characterization of the recessive resistance genes to Pea seed-borne mosaic virus (PSbMV)

Konečná, Eva January 2014 (has links)
Pea seed-borne mosaic virus (PSbMV) belongs among the most frequent viral pathogens causing severe yield and seed quality losses in field pea and other legumes. These losses might be the most effectively prevented by use of resistant varieties. Resistance to the common P1 strain of PSbMV is conferred by a single recessive gene (eIF4E), localized on LG VI (sbm-1 locus), while the resistance to lentil L1 strain is localized on LGII at sbm-2 locus. Germplasm of 2803 pea accessions was screened for eIF4E intron 3 length polymorphism using two sets of primer combinations, resulting in the detection of four eIF4EA-B-C-S variants, whose distribution was geographically structured. In order to identify gene underlaying sbm-2 locus, we have analyzed variation in the candidate eIF(iso)4E gene sequences from selected pea lines, reported as donors of resistance. we analyzed expression of both resistant and sensitive eIF4E alleles in F1 and F2 heterozygous plants, sensitive and resistant homozygotes after PSbMV infection, by qRT-PCR together with evaluation of viral concentration.

Molovky rodu Argyresthia na okrasných jalovcovitých, jejich škodlivost a možnosti regulace

Konečná, Hana January 2013 (has links)
Even 30 species of Argyresthia have been recorded in the Czech Republic. Several species are pests of fruit or ornamental trees. Argyresthia thuiella (Packard, 1871) and A. trifasciata (Staudinger, 1871) are species that have been imported into our country from other geographic areas. Monitoring Argyresthia thuiella and A. trifasciata was carried out in the castle park of Lednice, arboretum of the Mendel University in Brno, arboretum in Nový Dvůr and in the village Jelenice in 2007--2010. Argyresthia thuiella (Packard, 1871) overwinters as caterpillar inside twigs, it pupates in the following spring there. Moths are on the wing during June, up to the beginning of July. Argyresthia trifasciata adults were observed from mid May till the beginning of June. They reach the stage of maturity in October to December. They pupate in the debris under trees. Both species develop one generation annually. Argyresthia thuiella was found on Thuja occidentalis, T. plicata and Chamaecyparis lawsoniana; A. trifasciata on Juniperus virginiana, J. chinensis, J. sabina, J. × media, J. squamata, J. horizontalis; it wasn't found on Chamaecyparis pisifera, Juniperus conferta and Calocedrus decurrens. Both species cause mainly aesthetic damage to plants. In a stronger attack may occur damage to trees, or very young plants may die. Control possibilities were tested in both species.

Náchylnost odrůd bramboru k patogenům Streptomyces scabiei, Thanatephorus cucumeris a Helminthosporium solani způsobujícím choroby hlíz

Dejmalová, Jitka January 2014 (has links)
Susceptibility to three important pathogens causing potato skin diseases -- common scab, black scurf and silver scurf was studied in chosen varieties grown in the Czech Republic. The results were obtained in terms of severity and incidence of evaluated diseases for each variety and each year. The results made also possible to evaluate interactions of factors variety, earliness and year, mutual relationship among pathogens and secondary effect on presence of observed diseases, when the plants were treated with fungicides against late blight. None of varieties was resistant to observed diseases. The variety Mozart had the lowest average incidence of common scab, the variety Agria had this incidence the highest. The lowest incidence of black scurf was recorded for the variety Rosara, the highest for the variety Rebel. Belana was the best variety evaluated in the infestation of silver scurf, the worst was the variety Berber. The silver scurf caused by Helmithosporium solani was the disease with the highest incidence and also the highest severity of infestation of potato tubers what is unsuitable when the tubers are used for washing.

This thetis presents list of methods of plants protection and machines at work in a chemical plant protection. I tis presented their distribution and classification. The following is presented charakterization individual parts of sprinklers, the possibility of reducing drift spray liquid in the application and adjusting application rates. In the practical part by measuring flow rates of two types of nozzles, their comparison with set values and control the uniformity of flow rate nozzles around the application frame sprinklers.

Rostliny pro střešní zahrady

Jílková, Kristýna January 2016 (has links)
This Diploma thesis focuses on green roofs plants. The literary research covers attributes that are critical for choosing the right plants for green roofs and is defining qualities that are important for designing, founding and nurturing them. The theses address selection of plants that are suitable for extensive gardens. Plants that were recommended by authors were compared with those available on the Czech market. The experimental part of this theses evaluates several green roofs according to the methodology. The emphasis is put on plant vitality assessment. Field research results were compared with the literary research.
