The teoretical part of my bachelor thesis Growth correlations in cannabis plant is mainly focused on the issue of growth correlations. In the bachelor thesis, concrete examples of growth correlations are characterized including more details on problematics of apical dominance of the stem. The basic botanical, morphological and genetic characteristics of cannabis are also described, including important content substances. In the experimental part, the intensity of shoot branching of intact plants of selected technical and medical cannabis genotypes is investigated. The increase in length of axillary buds of first, second and third node was measured. Within the period of a few days, plant response to decapitation and exogenous auxin application was tested. In technical cannabis there was a strong response to exogenous application of auxin. On the other hand in the most cases of medical cannabis there was a reduced sensitivity to exogenous application of auxin. On the topic of shoot branching it was observed that the branching of medical hemp genotypes is significantly more intensive compared to the varieties od technical cannabis. The results of the grafting experiment then imply that the rootstock of technical cannabis did not influence the intensity of shoot branching of the medical cannabis scion.
