为了探明吲哚丁酸（Indole-3-butyric acid，IBA）对辣椒（Capsicum annuum L.）下胚轴不定根发生的诱导机制，采用IBA浸蘸后扦插的方法，研究了外源IBA处理后辣椒下胚轴不定根发生进程、糖类物质转化与不定根发生相关基因表达情况。结果表明：外源IBA诱导辣椒下胚轴不定根发生具有浓度依存效应，150 μmol ? L-1 IBA处理后不定根发生区段长度、不定根数及平均...
IBA对芍药扦插生根的影响及生根过程中相关酶活性的变化
芍药 扦插 生根 酶活性
2009/8/6
以芍药‘大富贵’品种为材料, 用1 000、2 000和3 000 mg·L-1 3个浓度的IBA处理进行扦插对比试验, 研究其生根过程中过氧化物酶( POD) 、多酚氧化酶( PPO) 、吲哚乙酸氧化酶( IAAO) 活性的动态变化。结果表明: IBA处理极显著地提高了插穗的生根率、根数和总根长, 其中以2 000 mg·L -1为IBA最佳生根浓度, 将生根周期缩短18 d, 并明显提高了生根...
不同浓度IBA处理对菊花水插生长的影响
观赏菊 水插 吲哚丁酸
2009/6/22
［目的］ 为菊花简便繁殖提供参考。 ［方法］ 取菊花不同生长时期的健壮枝条，插穗用高锰酸钾溶液消毒及吲哚3丁酸处理后进行水插培养，研究处理后插穗的生长情况。［结果］ 4月20日扦插比4月9日扦插的整体成活率高61%。经过消毒处理的插穗比未经消毒处理的插穗成活率高30%，4月9日经过200 mg/L IBA处理12 h的插穗全部死亡，100 mg/L IBA处理12 h的插穗成活率也偏低，4月...
