摘要：

为了检测不同浓度的乙酰胆碱和吲哚乙酸在柽柳扦插和管花肉苁蓉接种中的作用，用不同浓度乙酰胆碱和吲哚乙酸处理扦插柽柳，计算柽柳的成活率、生根数、根长和管花肉苁蓉接种率。1.5 mmol/L乙酰胆碱和吲哚乙酸对扦插柽柳成活率、生根数、根长和管花肉苁蓉接种率促进效果显著，而3.5 mmol/L的乙酰胆碱和2.5 mmol/L吲哚乙酸抑制作用明显，并且两者有相互抑制现象。低浓度的乙酰胆碱和吲哚乙酸提高了扦插柽柳成活率、生根数、根长和管花肉苁蓉接种率，而高浓度的乙酰胆碱和吲哚乙酸起到抑制作用，并且两者有相互抑制现象，说明乙酰胆碱和吲哚乙酸在柽柳生根上的作用位点可能一致或靠近。

Abstract:

The role of Acetylcholine (ACh) and Indole Acetic Acid (IAA) in cutting Tamarix chinensis Lour and vaccination rate of Cistanche tubulosa (Schenk) Whigt were investigated. With different concentrations of acetylcholine and indole acetic acid treatment, the survival rate, root number, root length of cutting Tamarix chinensis Lour and vaccination rate of Cistanche tubulosa (Schenk) Whigt were calculated. 1.5 mmol/L ACh and 1.5 mmol/L IAA markedly enhanced the survival rate, root number, root length in cutting Tamarix chinensis Lour and vaccination rate of Cistanche tubulosa (Schenk) Whigt, but 3.5 mmol/L ACh and 2.5 mmol/L IAA inhibited its and both had mutual inhibition. The results indicated that ACh and IAA markedly enhanced the survival rate, root number, root length and vaccination rate of Cistanche tubulosa (Schenk) Whigt in low concentrations, but inhibited its in higher concentrations in Tamarix cuttings, and both had mutual inhibition. All of the results supported that the postulation that the action sites of ACh and IAA in the rooting of Tamarix cuttings might be the same or similar.
