不同生长调节剂对盆栽美人蕉矮化效应研究

Dwarfing Effects of Different Growth Regulators on Potted Canna indica L.

[目的]研究矮壮素(CCC)、比久(B9)和多效唑(PP333)对盆栽美人蕉的矮化效应。[方法]以美人蕉"红色渐变"幼苗为对象,研究不同浓度的CCC、B9、PP333在不同施药方法下对美人蕉的矮化效应。[结果]叶面喷施80 mg/L PP333和盆内土施2 000 mg/L CCC均为抑制美人蕉"红色渐变"株高的理想措施。[结论]该研究可为有效控制盆栽美人蕉株高,提高其观赏价值提供理论依据。

[Objective]To study the dwarfing effect of CCC,B9 and PP 333 on potted Canna indica.[Method]The dwarfing effects of CCC,B9 and PP 333 with different concentrations,different application methods on the growth periods of C.indica‘Gradual Red’were investigated.[Result]The best way to restrain the height of‘Gradual Red’was spraying the leaves with 80 mg/L PP 333 or irrigating the soil with 2 000 mg/L CCC.[Conclusion]The study provided theoretical basis for controlling the height and enhancing the ornamental value of C.indica.
