摘　　要：为改善盆栽长寿花的观赏品质，笔者采用50-400mg／L不同浓度多效唑处理，探讨其对长寿花植株形态和开花的影响。结果表明：多效唑处理促使长寿花植株明显矮化并使花期提前，促进干物质向根、茎和花的分配比例。根据综合效果来看，多效唑最佳处理浓度为200mg／L。In order to create compact potted Kalanchoe blossfeldiana, effects of PP333 with different concentrations on the growth and florescence of Kalanchoe blossfeldiana were studied. The results showed that all the treatments shortened the plant height, advanced the blossom and increased the percent of dry matter partitioned to flower, root and stem. The optimal concentration of PP333 was 200mg/L.
