- 摘要:
- 以1年生李杏砧木木质化枝条为试材，采用NAA和IBA激素3个浓度50、100、200 mg·L-1处理枝条1 h，研究了从欧洲引进的4个李杏砧木硬枝扦插成活情况。结果表明：供试李杏砧木插穗根系快速生长期在扦插后5~6周；激素处理可以不同程度提高4个砧木品种硬枝扦插成活率；4个品种硬枝扦插成活率存在显著差异，其中25-39、2-1、9-5品种经过适宜激素种类和浓度处理可以取得较高的成活率。
- Abstract:
- One-year-old lignified branches of plum and apricot rootstock were used as test materials，treated 1 hour with 50，100，200 mg·L-1 NAA and IBA，in order to research the survival rate of four varieties of plum and apricot rootstock from Europe.The results showed that the rapid rooting period of test materials was 5-6 weeks after cutting，the hardwood cuttage survival rate of four rootstocks was improved in different degrees after phytohormones treatment，25-39，2-1 and 9-5 were suited for hardwood cutting if they were treated with suitable kinds and phytohormone concentrations.
