The aim of this study was to determine the effects of substrates and temperatures on Cynara cardunculus seed germination. The tests encompassed the following substrates - filter paper, sand and compost. The following temperature regimes were applied on each substrate used for germination tests: 20/30 degrees C (T(1)), 20 degrees C (T(2)) and 25 degrees C after 10-day chilling at 10 degrees C (T(3)). The analysis of variance showed that there were statistically significant differences between the first counts and the total seed germination, depending on the substrate type, temperature regime and medium x temperature regime interaction The highest germination was detected on filter paper, whereas the lowest was on sand. Furthermore, the highest germination was determined at a constant temperature of 20 degrees C (T(2)), while the lowest, at a temperature regime of 25 degrees C after 10-day chilling at 10 degrees C (T(3)).
