摘要
以牡丹品种‘冠群芳’为试材,分别在促成栽培的萌动期、小风铃期、撒飘期采用多效唑(PP333)、丁酰肼(B9)、正丁醇和TIBA等4种植物生长延缓剂进行处理,研究其对牡丹生长及开花的影响。结果表明:3个时期比较,小风铃期施用生长延缓剂矮化效果优于混合芽萌动期,而撒飘期施用则易发生药害。4种延缓剂相比,正丁醇效果比PP333和B9好,尤其是25mg/kg正丁醇处理,花期提前2d,成花率高达100%,成花质量最好,花径达17.2cm,新枝、叶、叶柄的生长也受到明显抑制;施用TIBA对植株影响显著,但易发生药害。
Potted tree peony ‘Guan Qun Fang’ was used to study effects of Paclobutrazol （PP333）, Daminozide （B9）, N-butanol and 2,3,5-triiodoberzoic（TIBA） in the stage of bud swelling, Leaf unfolding and Leaflet extending in green house. The results show that： compared to bud swelling stage, retardants treatment in Leaf unfolding stage is recommended,while it is prone to have a harmful effects in Leaflet extending stage. N-butanol can enhance the blossom rate, advance flower time of 2 days and inhibit the growth of plant. Following is Paclobu-trazol and Daminozide. The suitable concentrations of N-butanol is under 25mg/kg. 2,3,5-triiodoberzoic has a significantly influence on the growth and the flowering, and it is apt to led to Poisonous effect on the plant.
