摘　　要：以不同SH40实生后代为中间砧的"红富士"苹果为试材,研究了不同中间砧对"红富士"苹果树体生长以及过氧化物酶(POD)、超氧化物歧化酶(SOD)活性和总酚含量的影响。结果表明:不同中间砧对"红富士"苹果树体生长影响较大,其中以2号、6号作中间砧的果树矮化性状明显;秋季落叶前各试材叶片中POD活性差异较大且与"红富士"苹果树体的生长势呈负相关,各试材叶片中总酚含量与"红富士"苹果树体的生长势呈正相关。Taking ＇Red Fuji＇ apple trees that grafted onto SH40 seedling interstocks as materials,the effects of different seedling interstocks on the growth of tree,POD and SOD activity and total phenol content in leaves of ＇Red Fuji＇ apple were studied. The results showed that the effects of different interstocks on the growth of tree were obvious,and ＇Red Fuji＇ apple trees on No. 2 and No. 6 seedling interstocks showed a significant feature of dwarfing. Great differences of POD activities existed in leaves of different experimental materials and there was a significant negative correlation between POD activities and the growth potential of ＇Red Fuji＇ apple trees grafted onto SH40 seedling interstocks before leaf abscission in fall, and there was a significant positive correlation between total phenol content and the potential of ＇Red Fuji＇ apple trees.
