| 摘 要： | 2004年在北京门头沟区科技开发实验基地研究了核桃子苗嫁接技术和核桃子苗砧嫁接过程中相关生理指标的变化.结果表明:2 000 mg·L-1GA3浸泡种子、摘心处理能显著提高砧木茎粗度;愈合环境温度控制在26 ℃,锯末含水量控制在410 g·kg-1,箱上打孔,嫁接成活率可达80%以上;子苗展真叶1 ～10片时,IAA、GA3、ZR含量与IAA/ABA值相对较高;砧穗愈合过程中,砧木的可溶性糖、蛋白质含量与IAA/ABA值先降后升再降,PPO活性呈相反趋势,IAA、GA3、ZR含量先降后升,ABA含量一直呈缓慢上升的趋势. |

| Abstract: | The integrated exper iment of young w alnut seed ling g raft ing w as carried out in greenhouse to study thetechniques and change of physiolog ical indexes on graft ing uniting process o f walnu.t The result show ed that thetreatm ents of 2 000mg L-1GA3 and p inching enhanced ev ident ly the diameter o f stem of the seedling, the g raftingsurv iva l rate w as above 80% w ith temperature at 26 andmed ia moisture at 410 g?? kg-1 in box with holes. Theyoung seedling had the higher hormones content of IAA, GA3, ZR and IAA /ABA value dur ing the leaves expanded 1~ 10. The physio log ical indexes of stock changed w ith t ime in the process of healing , the content of solub le sugar,pro tein and IAA /ABA value went down at earlier stage, went up in them idd le, then w en t dow n aga in at la te stage,the PPO activ ity had a tendency of opposite, the content of IAA, GA3, ZR dec lined at earlier stage, then went up afterw ards, ABA content rose stead ily in the whole process. |
