| 摘 要： | 用5种生长调节剂处理唐古特白刺插条进行容器扦插育苗试验。结果表明:萘乙酸300 mg.kg-1对唐古特白刺生根数目以及新生枝数和新生枝生长量都有明显的促进作用;6号生根粉100 mg.kg-1对唐古特白刺根长生长有明显的促进作用;吲哚丁酸200 mg.kg-1对其新生枝数促进作用明显。综合分析表明,唐古特白刺扦插育苗最佳的生长调节剂为萘乙酸300 mg.kg-1。

| Abstract: | With five different somatomedins,N.tanguturum's branch were treated to conduct for cutting and seedling raising tests in container.The results showed: 300 mg·kg-1 of NAA had evident promoting effect on N.tanguturum rooting number,new branch number,and new branch growth.100 mg·kg-1 of ABT had evident promoting effect on N.tanguturum root growth.The promoting effect of 200 mg·kg-1 of IBA on its new branch number was evident.The integration analysis showed the best somatomedin for N.tanguturum cutting and seedling raising was 300 mg·kg-1 of GA3 |
