AB  - The present paper shows results obtained on effects of priming of sunflower seeds, subjected to accelerated ageing and the cold test, on seed vigour. Seeds were primed with distilled water, the potassium nitrate solution (0.2%) and the gibberellic acid solution (0.04%). The following parameters were tested: energy of germination, germination, proportion of abnormal seedlings, lengths of roots and shoots of normal seedlings. Accelerated ageing in the course of 3 and 5 days resulted in a statistically significant reduction in energy of germination and germination; it adversely affected the length of roots and shoots and it increased the proportion of abnormal seedlings. Seed priming with all three solutions mitigated adverse effects of 3-day accelerated ageing on energy of germination. Furthermore, seed priming with gibberellic acid prior to 3-day accelerated ageing positively affected seed germination and neutralized a negative effect of accelerated ageing on the number of abnormal seedlings, as well as on lengths of shoots and roots of normal seedlings. The cold test (at 5°C for 7 days) negatively affected energy of germination and the root length, increased the proportion of abnormal seedlings and did not affect seed germination. Priming of seeds with distilled water prior to the cold test completely neutralized the adverse effect of low temperatures on energy of germination. Finally, priming of seeds with all three solutions completely neutralized the adverse effect of cold test on the root length.

AB  - 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 follow-ing temperature regimes were applied on each substrate used for germination tests: 20/30°C (T 1), 20°C (T 2) and 25°C after 10-day chilling at 10°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, tempera-ture regime and medium × 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°C (T 2), while the lowest, at a temperature regime of 25°C after 10-day chilling at 10°C (T 3).
