以三年生红富士（Mlaus domestica Borkh．cv．Red Fuji）/SH/八棱海棠（Malus micromalus Makino）为试材，研究不同短截程度对苹果树体内源激素含量变化的影响。结果表明，不同短截处理均降低了植株茎尖、细根内吲哚乙酸（IAA）含量。春梢开始生长期茎尖脱落酸（ABA）含量重短截＞中短截＞轻短截，分别为224.85、204.95和189.16 ng/g， FW，重短截与对照处理间差异不显著。春梢旺长期和春梢缓长期4个处理茎尖及细根ABA含量呈重短截＞中短截＞轻短截＞对照的趋势。不同处理间植株茎尖、细根中赤霉素（ GA）、玉米素核苷（ ZR）含量变化不显著。在整个春梢生长期，4个处理下茎尖和细根的（ IAA＋GA＋ZR）/ABA比值随短截程度加重而降低，短截处理降低了茎尖IAA、（ IAA＋GA＋ZR）/ABA，提高了ABA含量，一定程度上削弱了生长势，抑制了新梢生长。

Three-year-old apple trees(Mlaus domestica Borkh.cv.Red Fuji)/SH/Malus micromalus Makino were used to study effects of short-cutting on dynamic changes of endogenous hormones .The results show that the contents of endogenous IAA in shoot tips and fine roots are reduced under the treatments .At the early vigorous growing period of shoots , the contents of ABA in shoot tips are in the following order:heavy short-cutting >middle short-cutting >light short-cutting, which are 224.85, 204.95 and 189.16 ng/g, FW respectively, and the difference of the contents between the heavy short-cutting and the control is not significant .At the vigorous growing period and slow growth period of shoots , the contents of endogenous ABA in shoot tips and fine roots under the short-cutting are significantly higher than those of the control , while the changes of the contents of ZR and GA are not significant.The ratios of(IAA+GA+ZR)/ABA in shoot tips and fine roots are decreased with the increase of pruning length .The contents of IAA and the ratios of ( IAA+GA+ZR) to ABA under the short-cutting treatments are decreased , while the contents of ABA in shoot tips are increased , which weakens the new shoots and plant growth .
