- 摘要:
- 以长白山区野生地椒百里香为试材，研究了不同浓度、不同生长调节剂、不同时间处理对地椒百里香嫩枝扦插繁殖的影响。结果表明：植物生长调节剂对平均生根率的影响为ABT>NAA>IBA，分别为94.22%、90.69%、81.33%。但是嫩枝扦插后根部长势最好在NAA 1 000 mg/L(1 s)。因此，长白山区野生地椒百里香嫩枝扦插时，建议选择ABT生根剂。选用ABT生根剂时，处理浓度间差异不大，但浓度500 mg/L(2 min)时优于其它处理组。当选用NAA溶液时，处理浓度间差异较大，且随着处理浓度的增加效果更佳，最佳处理为1 000 mg/L(1 s)。当选用IBA溶液时，随着浓度增加，生根率及根部长势越差，50 mg/L(12 h)为最佳处理。
- Abstract:
- The effect of different phytohormones and concentration and treatment time on cutting propagation was analyzed using wild Thymus quinquecostatus in Changbai Mt.The results showed that the effect of plant growth regulators on average rooting rate was ABT>NAA>IBA，each was 94.22%,90.69%,81.33%.But the best rooting growth was NAA 1 000 mg/L(1 s) treatment.ABT solution was suggested when cutting wild Thymus quinquecostatus in Changbai Mt.area.Selecting ABT solution was little difference in treatment concentration，but the best was 500 mg/L(2 min).When we selected NAA solution there were differences among treatments，with the increase concentration，the effect was better，the best treatment was 1 000 mg/L(1 s).For IBA solution there were differences among treatments，with the increase of concentration，the rooting rate and rooting growth were worse，the best treatment was 50 mg/L(12 h).
