Studiu klíčivosti a vzcházivosti semen technického konopí / Study of germination and emergence of industial hemp seeds

Nowadays hemp is listed among plants with a wide range of potentials. It can be used as a source of fibre, oil, food or medicine. The aim of this work was to investigate optimal conditions for hemp seed germination grown in laboratory as well as field conditions and to propose the application of acquired findings. Hemp seed was split into 2 size groups: above 3 mm and 2 - 3 mm. Divided seeds with the humidity level of 6, 9 and 12% were stored at the temperature of 0, 8 and 20? 1°C for half a year. In 2 months interval, there were evaluated: germination, energy of sprouting, speed of sprouting, further seed viability and laboratory emergence. From next influences were evaluated the influence of dryness, wetting, autotoxicity, exudates of perennial weeds, seed treatment with the infusion of field horsetail and the grown stimulator. The best germination and laboratory emergence had seeds stored at 0°C. Test of seed viability confirmed significant decline in live seeds stored over 4 months at the 0°C temperature. The best germination was achieved by seed size 2 - 3 mm. Hemp requires sufficient amount of water for germination. Leachates from rhizomes of couch grass inhibited germination of hemp by 10%. On the other hand, germination was significantly increased by the stimulator.
