| 摘 要： | 楸树(Catalpa bungei)作为扦插难生根树种,普通扦插技术成活率一直很低,少见其扦插技术系统研究报道(郭从俭等,1993;梁明武,2002).近年来,豫楸1号(C.bungei cl.‘Yu-l')作为从楸树中选育的良种在全国范围内得到了大面积推广.但该品种主要通过嫁接繁殖,第1年培育砧木,第2年嫁接,繁育周期长、费用高,不利于良种迅速推广,制约这一优良品种的发展(王新建等,2005).

| Abstract: | The article investigated the changes of nutrients(total sugar,total nitrogen,total sugar/total N)and oxidases(IAAO,POD,PPO)of Catalpa bungei cl.'Yu-1' in the cutting rooting process.The results showed that:C.bungei cl.'Yu-1' cutting rooting initiated from the lenticel.The soluble protein in the forced-sprouting cuttings decreased dramatically in the early stage,and then the decrease tended to slow.The total sugar content slowly increased throughout.The total nitrogen had a little change.The total sugar/tota... |
