摘　　要：用3000mg／L或5000mg／L的6-BA对德国鸢尾（Iris germanica）‘Lovely Again’进行单次喷施，可以促进根茎芽的萌发和根状茎的形成。在喷施后的30～90d，6-BA的促进作用在具有2个或4个起始根状茎的植株上表现得很显著，但对于只有1个起始根状茎的植株不显著。在喷施后的150d以及第2年，具有2个或4个起始根状茎的母株总体上比只具有1个起始根状茎的母株产生了更多的根状茎。而6-BA的喷施对母株的叶面积和叶片数、总叶面积以及总叶片数没有影响。A single foliar application of 6-BA at 3 000 or 5 000 mg/L stimulated axillary and rhizomic budbreak and rhizome formation in Iris germanica ‘Lovely Again＇. The effect of 6-BA application was more significant on plants with two or four initial rhizomes but not on those with one initial rhizome at 30 d （ days after treatment）, 60 d and 90 d. Stock plants with two or four initial rhizomes generally formed more rhizomes than stock plants with one initial thizome at 150 d and the next year. However, leaf area and changes in leaf number of stock plants, total leaf area and changes in total leaf number were not affected by 6-BA application.
