Poor seed germination is a main hindrance to the commercial cultivation of Zinnia (Zinnia elegans Jacq.). Seed enhancement is a useful strategy to improve germination of major agronomic and horticultural crops. A lab study was conducted to investigate the potential of magnetic seed stimulation as a seed enhancement tool and its influence on germination and emergence capacity of zinnia. Magnetic seed treatment with 50, 100 and 150 mT strength each for 5, 10 and 15 min was compared with control (untreated). Magnetic seed stimulation reduced time to 50% germination and mean germination time and increased final germination percentage, germination energy and germination index. Root length, shoot length, seedling fresh and dry weight was also increased as a result of magnetic seed stimulation. Furthermore, magnetic field treatment also enhanced α-amylase activity, total soluble sugars and reducing sugars levels. Among all seed treatments, magnetic field with strength of 100 mT for 15 min was the most effective physical treatment for improving seed germination and seedling growth of zinnia.

Słabe kiełkowanie nasion jest główną przeszkodą w komercyjnej uprawie cynii (Zinnia elegans Jacq.). Wzmocnienie nasion jest użyteczną strategią w celu poprawienia kiełkowania głównych upraw rolniczych i ogrodniczych. Doświadczenie przeprowadzono w celu zbadania potencjału magnetycznej stymulacji nasion jako narzędzia wzmocnienia nasion i jej wpływu na kiełkowanie i zdolności wschodów cynii. Z kontrolą (bez zabiegów) porównano zabiegi działania magnetycznego na nasionach z siłą 50, 100 i 150 mT przez 5, 10 i 15 min. Magnetyczna stymulacja nasion zmniejszyła do 50% czas kiełkowania i średni czas kiełkowania oraz zwiększyła ostateczny procent kiełkowania, energię kiełkowania i wskaźnik kiełkowania. W rezultacie magnetycznej stymulacji nasion zwiększyła się też długość korzenia, długość łodygi oraz świeża i sucha masa. Ponadto zabieg pola magnetycznego wzmógł aktywność α-amylazy oraz poziom całkowitej zawartości cukrów rozpuszczalnych i cukrów redukujących. Wśród wszystkich zabiegów na nasionach, pole magnetyczne o sile 100 mT działające przez 15 min było najbardziej skutecznym zabiegiem poprawiającym kiełkowanie nasion i wzrost siewek cynii.
