The freeze injury of Nerium indicum 'Variegatum'leaves at the low temperature was studied in Cixi areas.The results showed that the freeze injury occurred in the leaves near the top of branch of Nerium indicum 'Variegatum' at-5.5℃ in Cixi,but no plants were frozen to death.New buds could sprout near the parts of freeze injury(including 4 joints of branches or 12 leaves) and grow normally.In comparison with Nerium indicum,the freeze injury degrees of leaves of Nerium indicum 'Variegatum' was more serious.The freeze injury degrees of leaves in the windward were more serious than that in the leeward and the leaves near top branch were easier to be damaged.
