摘　　要：【目的】降低盆栽无花果株高并提高其观赏性。【方法】以无花果波姬红为试材,萌芽展叶后根施不同浓度的多效唑、烯效唑和矮壮素溶液,研究不同处理对叶片生长、结果能力和嫩梢生长的影响。【结果】结果表明,根施3种植物生长调节剂后,均降低了盆栽无花果叶长、叶宽、株高和冠幅,提高了叶绿素含量、单株结果数、单果质量、可溶性固形物质量分数和新梢基部粗度。【结论】不同处理中萌芽展叶后根施浓度40 mg/L烯效唑的综合效果最佳,建议在无花果盆景制作中参考应用。【Objective】The aim was to reduce the plant height of potting fig and improve its ornamental value.【Methods】With fig Bojihong cultivar as test material,different concentrations of PP_(333),S_(3307),and CCC solution were applied to the roots after germination and leaf expansion.The effects of different treatments on leaf growth,fruiting ability and shoot growth were studied.【Results】The results showed that after root application of three plant growth regulators,the leaf length,leaf width,plant height and crown width of potting figs were reduced,and the chlorophyll content,fruit number per plant,single fruit weight,soluble solids content and new shoot base roughness were increased.【Conclusion】The comprehensive effect of root application of 40 mg/L S_(3307) after bud exhibition period was best in all treatments,which should been applied in bonsai making.
