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.

Key words: interstock, scion's leaf, rootstock's root, carbohydrate, annual change

摘要： 以华红脐橙/3种中间砧/枳为试材进行田间试验,研究不同中间砧对接穗叶片和基砧根系中碳水化合物含量的双重影响。结果表明,接穗叶片可溶性糖含量、基砧根系淀粉和总糖含量的年动态变化趋势基本相似,而在接穗叶片淀粉含量年动态变化的早期趋势和总糖含量年动态变化的后期趋势、基砧根系可溶性糖含量的年动态变化趋势上则有明显的差异。在一年中的绝大多数时期里,接穗叶片和基砧根系的3种碳水化合物含量在不同中间砧之间有明显的差异。
