The electric conductivity of root on shoots of cherry grafting seedlings (Zaohongbaoshi/Dawolouye) and culturing seedlings (Zaohongbaoshi) was measured, and the damage rates were counted. And combination with growth resuming method, the two seedling's hardness was appraised. The shoots of grafting seedling and culturing seedling achieved sub-lethal temperature about - 22℃, but the roots of grafting seedling and culturing seedling achieved sub-lethal temperature about - 9℃.Therefore, they were similar in hardness level. The culturing seedlings could be considered to apply in cultivating area of grafting seedling.
