Abstract: Taking Huahong navel orange/three kinds of interstock/Poncirus trifoliate as materials, the field experiment is conducted to study the double effects of different kinds of interstock on the content of carbohydrates in scion's leaves and rootstock's roots. The results indicated that three kinds of interstock had no effects on the tendencies of the annual changes in total soluble sugars in scion's leaves and in the contents of starch and total carbohydrates in rootstock's leaves. With the respect of annual changes, three kinds of interstock varied in early tendency of starch content and in late tendency of total carbohydrates in scion's leaves and in tendency of total soluble sugars in rootstock's roots. The carbohydrate contents in most of different periods had significant difference among three kinds of interstock.
