Effects of exogenously foliar applied glycine betaine (GB) on the growth and contents of osmolyte in tomato seedling was investigated. Plants treated with exogenous glycine betaine induced better biomass production and plant height during chilling stress than the untreated plants. The total soluble sugar contents in GB foliar-applied plants lower than that of untreated plants 28 days after foliar application. Total water soluble protein contents in GB foliar-applied plants did not change 28 days after chilling stress. In untreated plant, it decreased rapidly in the beginning of chilling stress. Proline contents in untreated plants rapidly increased by the beginning of chilling stress, and then slightly decreased during the next 3 weeks. However proline contents in GB foliar-applied plants did not change during the 28 days chilling stress period. The results suggest that foliar application of GB is a effect methods to increase the chilling tolerance of tomato seedlings in protected cultivation system at low temperature season.
