| 摘 要： | 以100、200、300mg·L^-1的KT溶液浸泡油茶芽苗砧接穗，以清水处理为空白对照，研究KT处理后的油茶芽苗砧接穗对其嵌合体发育的影响．结果表明，经KT处理后的嵌合体成活率明显高于对照，其中100和200mg·L^-1浓度的KT溶液处理效果较好．嵌合体成活率与PPO活性呈极显著正相关，与POD活性呈显著负相关．接穗经低浓度KT浸泡后再进行嫁接，有利于嵌合体的愈合及成活率的提高．

| Abstract: | By comparing the scions of Camelia oleifera soaking in the KT concentration of 100,200 and 300 mg·L^-1with those in the pure water as control treatment （CK）, the result showed that the grafted union of C. oleifera nurse seed soaking with KT had higher survival rates, and the treatment of KT concentration of 100 and 200mg·L^-1had better efficiency. There was a highly sig- nificant correlation between survival rate and PPO activity, and there was a significant negative correlation between survival rate and POD activity. The scions soaking with low concentration KT, had a better healing and higher survival rate. |
