Abstract:: Currently，SH40 is the major application of apple dwarfing rootstocks in North China.During the production，SH40 interstocks segment apple seedling temporary planted would have the phenomena that loss water and occurs wrinkles at interstocks segment first and then even expand to the whole plant after the spring thaw soil，which is prejudicial to the production extremely.In this study，annual winter hibernation Fuji/SH40/Robusta was used as material and the reasons that the temporary planting SH40 interstocks apple seedling loss water in interstocks first during dormancy were studied.The results showed that,the reason that temporary planting SH40 interstocks seedling loss water at interstocks first during the dormancy period had not much relations to its varietal characteristics；the transpiration of roots system was a major reason that cause the interstocks segment loss water and occurs wrinkles first，and when the root lack water as well as the transpiration was large，there was a water potential difference in the conduit，which forced the migration in interstocks move to the roots reversely.Meanwhile，the larger root system was，the faster water loss rate was and the dehydration wrinkle was much more serious as well；the threshold that the interstocks and scion could rehydration successful was 20% of water loss rate，and the seedling cannot survive beyond the threshold.
