The literary part is focused on hop growing not only in Czech republic but also in the world, botanical and biological characterization of hops as a agrobiological requirements and the technology of growing. For the evaluation of hops, in a practical part, were chosen methods of mechnical tests according to ČSN 46 2520 - 4, 5, 10 and methods of determination of humidity of hops according to 46 2520 - 3. We were also trying to find out parameters enabling evaluation of anatomical structure of hops heads. Samples of hops were picked up from chosen agricultural company AGRAS Želátovice, which is situated in hops area around Tršice. Tests covered determination of foreign and hops admixtures, determination of humidity, determination of content of seeds. Also the weight of 100 heads was watched than percentage of hop spindle, the lenght of hop spindle, the weight of hops and the density of hop spindle. From the tests which have been made we realized that the variety has an influence on the lenght, density of hop spindle and also on the weight of 100 heads. We also know from the results that there is necessity of regular yearly inspection of surrounding lands hop garden on the presence of male plants and also on observance of storing conditions of hops. |
