摘　　要：为缓解两面针茎枝叶多锐刺导致日常管理困难的问题,提高其药用部位产量,建立两面针栽培新模式,本研究采用不同浓度梯度的多效唑、烯效唑、矮壮素及缩节胺生长调节剂对两面针植株进行矮化试验,筛选出对两面针矮化效果最佳的处理方式,并对处理后的两面针叶片特征进行研究。结果表明,多效唑1000 mg/L和烯效唑200 mg/L处理对两面针的矮化效果较好且稳定;气孔对矮壮素800 mg/L、缩节胺400 mg/L处理较为敏感,明显变小;保卫细胞对4种生长调节剂处理均比较敏感。矮化研究可为两面针种植发展提供理论和技术支撑。In order to alleviate the problem of daily management difficulties caused by sharp thorns in the stems and leaves of Zanthoxylum nitidum,improve the yield of its medicinal parts,and establish a new cultivation mode for Zanthoxylum nitidum,this study conducted dwarfing experiments on Zanthoxylum nitidum plants by using different concentration gradients of growth regulators including paclobutrazol,uniconazole,chlorocholine chloride and mepiquat chloride.The best treatment method for dwarfing Zanthoxylum nitidum was selected,and the characteristics of the treated Zanthoxylum nitidum leaves were studied.The results showed that the dwarfing effects of paclobutrazol 1000 mg/L and uniconazole 200 mg/L were good and stable;the stomata were more sensitive to the treatment of chlorocholine chloride 800 mg/L and mepiquat chloride 400 mg/L,and the stomata became significantly smaller;guard cells were sensitive to all four growth regulators.Dwarfing research can provide theoretical and technical support for the development of Zanthoxylum nitidum planting.
