- 摘要:
- 以“火焰”“兰贵人”“云之蝶”香石竹为试材，采用100 mg?L-1浓度的NAA、IAA 和IBA 3种生长调节剂对3个品种插穗进行扦插生根处理。结果表明：NAA处理对3种香石竹扦插的生根数、根长、根幅的影响均最好，IBA处理次之。NAA处理对“火焰”生根数、根长的生长有明显的促进作用，NAA、IAA 和IBA处理对“火焰”的根幅影响不明显；NAA处理对“云之蝶”生根数、根长和根幅均有明显的促进作用；IBA处理对“兰贵人”生根数、根幅的生长有明显的促进作用，NAA、IAA 和IBA处理对“兰贵人”扦插的根长影响不明显。“火焰”“云之蝶”插穗生根选用NAA处理较好，“兰贵人”插穗生根选用IBA较好。
- Abstract:
- Three carnation of ‘Flame’‘Rendes-vous’‘Cloud butterfly’ were used as materials，the influence of three growth regulator NAA，IAA，IBA in 100 mg?L-1 on the root growth of carnation cutting was studied.The results showed that NAA treatment was the best for root growth of three kinds of carnation cutting seedlings，which got the biggest root number，root length and root width，followed by IBA.NAA treatment significantly promoted the growth of ‘Flame’ root number and root length，and the root number，root length and root width of ‘Cloud butterfly’.The root number and root width of ‘Rendes-vous’ were significantly promoted by IBA，while both the width of ‘Flame’ root and the length of ‘Rendes-vous’ root had no obvious increase after all three kinds of growth regulator treatment.The results indicated that NAA treatment was the best for root growth of ‘Flame’ and ‘Cloud butterfly’，and IBA was better for ‘Rendes-vous’.
