In order to improve the physiological quality of aged broccoli seed (Brassica oleracea var. Waltham29), in this study a variable magnetic field (VMF) of 3.6 mT, 60 Hz by 5min was used as pre-sowing treatment. The accelerated aging treatment was applied for 0, 48 and 72 h (AA0h, AA48h and AA72h) and then the VMF treatment, under a randomised complete block design with 4 replications of 30 seeds. For seeds aged for 72 h a final germination of 20% was obtained, whereas without magnetic stimulation it was null. However, the magnetic bio-stimulation in 48 h aged seeds was significantly negative, reducing the final germination by 45.83% compared to the treatment without magnetic field, while the VMF effects in unaged seed were zero. The variable magnetic field effects depended on the seed aging time, resulting in positive, negative and null outcomes (responses) in vigour variables.

W celu uzyskania poprawy właściwości fizjologicznych nasion brokuła (Brassica oleracea var. Waltham 29) poddanych przyspieszonemu starzeniu, zastosowano przedsiewne zmienne pole magnetyczne (VMF) o wartości 3,6 mT, 60 Hz przez 5 min. Proces przyspieszonego starzenia prowadzono przez 0, 48 and 72 h (AA0h, AA48h i AA72h), po czym nasiona poddawano działaniu VMF. Badanie prowadzono metodą bloków losowych w 4 powtórzeniach po 30 nasion. Przyspieszone starzenie przez 72 godziny spowodowało wzrost wskaźnika kiełkowania nasion o 20%, podczas gdy dla próby bez działania pola magnetycznego wynik był zerowy. W przypadku nasion poddanych starzeniu przez 48 godzin efekt stymulacji magnetycznej był negatywny, powodując spadek końcowego wskaźnika kiełkowania o 45,83% w porównaniu do wariantu bez pola magnetycznego. Dla nasion niepoddawanych starzeniu wpływ działania VMF był zerowy. Wpływ działania zmiennego pola magnetycznego na nasiona był uzależniony od czasu starzenia nasion, powodując pozytywne, negatywne lub zerowe zmiany w wartościach wskaźników ich wigoru.
