Influence of rootstock on growth and fertility of choosen sweet cherry varieties
Englisch, Jakub ; Sus, Josef (advisor) ; Zíka, Lukáš (referee)
The main aim today is to improve the cultivation of fruits and intensification of production for satisfactory market supply quality products. This can be achieved by selecting an appropriate combination of base-variety and cultivation using perspective shape (spindle). The newly founded modern planting in the growing spindle-shaped when in use slow- growing rootstock up to several hundred more trees per hectare of orchards and fertility beginning to enter the third year, which is significantly earlier than in past years. In earlier planting was used, lusher rootstocks, but also used other forms of cultivation. Weakly vigorous rootstocks were represented in my attempt rootstock P-HL-A and Gisela 5.
The theoretical part focuses on the general demands of growing cherries, cherry growing importance and its botanical description, pests and diseases cherry rootstock influence on the variety and rootstock description. The experimental part of the work specializes in the characterization of habitat and experimental material, describes methods of assessment and method of the experiment itself, the experiment results and the conclusions drawn. The aim of the study was to assess the effect of different rootstocks on growth and fertility, selected varieties of cherries grown in the shape of the spindle in the third and sixth year after planting.
In the course of short-term plantings of cherries grown in the shape of the spindle it showed that rootstock P-HL-A variety 'Burlat' had a 19% increase compared with lusher 'Karešova' variety was planted on the same rootstock. Although the variety 'Karešova' had a smaller volume of crowns and reached compared to the variety 'Burlat' higher overall revenue (10.4%) and higher specific revenues, but the variety 'Burlat' reached about 10% higher compared to the average weight of the fruit variety 'Karešova'. Variety 'Sweet Early Panaro 1' on Gisela 5 rootstock had a 21% growth compared to the wilder variety 'Rita' (Gisela 5), higher total return (16.7%) was recorded in the variety 'Sweet Early Panaro 1', but specific (specific) revenues were a variety 'Rita' almost the same. Among the varieties 'Rita' and 'Sweet Early 1' Panaro was a big difference in the mean fetal weight. Variety 'Sweet Early Panaro 1' had a 40% higher compared to the average weight of the fruit variety 'Rita'.
