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.
