Abstract: The tomato seedlings, of which the seeds were treated by magnetic field, at both cotyledon and euphylla stage exposed under the same lower temperature with different time durations.The result showed that when the seedlings were treated by magnetic field the activity of SOD and CAT as well as the content of GSH and soluble protein in cotyledon seedling were higher than the control.Therefore, the chilling injury symptoms of treated seedlings were alleviated.

Key words: Tomato seedling, Magnetic field, Chilling stress, Protective enzyme.
