摘　　要：为了培育观赏价值更高的梅花(Prunus mume Siebold & Zucc.)盆栽产品,探究不同浓度烯效唑对盆栽梅花幼苗生长和株型的影响。试验选取6个梅花品种盆栽幼苗作为研究对象,采用3种不同浓度烯效唑叶面喷施处理,并以清水处理为对照。结果表明,叶面喷施100~300 mg/L烯效唑显著降低了不同品种盆栽梅花幼苗株高和冠幅的增长量,且烯效唑浓度越高抑制作用越强。烯效唑浓度为300 mg/L时,6个梅花品种幼苗株高和冠幅的增长量可分别降低27.50%~80.05%和39.45%~83.93%。3种浓度烯效唑对不同品种盆栽梅花幼苗侧芽萌发均有促进作用,对基径和分枝茎粗增长、分枝长和节间距生长存在抑制作用,并随着烯效唑浓度的升高,分枝长和节间距越短。从盆栽梅花幼苗株型调控整体效果来看,叶面喷施300 mg/L烯效唑是较优的选择,使得盆栽梅花株型紧凑饱满,观赏效果最佳。The aim of this study was to investigate the effects of different concentrations of uniconazole on growth and plant type regula⁃tion of potted Prunus mume seedlings,and hence to cultivate more potted Prunus mume products with higher ornamental value.Six cul⁃tivars of potted Prunus mume seedlings were selected as the research objects,and three different concentrations of uniconazole were used for foliar spraying treatment,with water treatment as the control.The results were as follows,foliar spraying of 100~300 mg/L uni⁃conazole decreased the growth of plant height and crown width of different cultivars of potted Prunus mume seedlings significantly,and the increase in the concentration of uniconazole could evidently enhance the inhibitory effect.Additionally,at the concentration of 300 mg/L of uniconazole,the growth of plant height and crown width of potted Prunus mume seedlings in six cultivars could be declined by 27.50%~80.05%and 39.45%~83.93%,respectively.Three different concentrations of uniconazole could improve the lateral bud ger⁃mination in diverse potted Prunus mume seedlings,but inhibit the growth of basal diameter,branch stem thickness,branch length and internode length.Furthermore,the rise in the concentration of uniconazole could shorten the branch length and internode length.In summary,the study results suggest that from the perspective of the overall effect on regulating the plant type of potted Prunus mume seedlings,foliar spraying of 300 mg/L uniconazole was the optimal choice,which could make potted Prunus mume compact and fullcrowned,with the best ornamental effect.
