Spatial layout of the root system of hop in Czech Republic
Original language description
KROFTA, Karel, Václav BRANT, Jaroslav POKORNÝ, Milan KROULÍK, Petr ZÁBRANSKÝ, Jana ŠNIDLOVÁ and Lenka MRAVCOVÁ. Spatial layout of the root system of hop in Czech Republic. In: F. WEIHRAUCH, ed. Proceedings of the Scientific-Technical Commission 25 – 29 June 2017, St. Stefan am Walde, Austria. Wolnzach: Scientific-Technical Commission of the International Hop Growers´ Convention, 2017, p. 109. ISSN 2512-3785. For a full understanding of the plant’s response to habitat conditions, among other things the knowledge of the development, morphology and functionality of the root system is fundamental. In terms of its anatomy, spatial layout, physiology and chemical composition the root system provides basic information about interactions between the plant and its environment. Soil conditions and characteristics of the soil profile influence the formation of the root system of hops. Between 2015 and 2017 several excavations of the root system of three Czech hop varieties ranging in age from 3 to 14 years were carried out in the Saaz hop growing area (locality Steknik near Žatec, elevation 197-203 m a.s.l.). The soil profile at the evaluated localities was characterized by quaternary sediments from the holocene and pleistocene, consisting of topsoil and brown to red clays. Under the surface layer, the sediment deposits were represented by black-gray clay and sandy clays. Large amount of soil was removed by means of heavy machinery. Preparation of the root system was completed by manual removing of the soil from the root zone. During the preparation of the roots, their spatial layout was recorded in the soil by means of markers placed on the spine roots. The position of the roots was determined based on axial coordinates x /y /z from the center of the crown. After the roots were removed from the ground, their spatial reconstruction and subsequent graphical analysis were performed using infrared images.
