摘要：Explore and obtain the effects of irradiated Ocimum basilicum seeds on the biological mechanisms of germination and seedling growth in the specified frequency bands. In the experiment, two influencing factors of the specified frequency band and irradiation time were set, and different gradients of irradiated seeds were set. Non-magnetized treatment was used as a blank control group (CK) to determine the changes in the main chemical components in seeds and seedlings, and explore the radiation breeding biology mechanism. The results showed that 90 kHz-100 kHz had a significant inhibitory effect on seed germination, and the 50 kHz-70 kHz band had a significant effect on the germination of Ocimum basilicum, with 50 ± 2.0 kHz being the best. In the time gradient exploration, the main chemical content of seeds was the highest when irradiated for 20 min, and the growth effect of seedlings was the best. The specified frequency band (EMF) has the effect of promoting and inhibiting the germination and growth of basil. It stimulates the internal chemical composition to break the dormancy period of the seed, accelerates the anabolism, and increases the molecular assimilation of the building.
