摘　　要：用GGR6号浸泡荷兰菊幼嫩插穗基部1h、2h和4h,浸泡浓度分别为0mg·L-1、10mg·L-1、20mg·L-1和30mg·L-1。结果表明:GGR6号浸泡荷兰菊嫩枝幼嫩插穗,可显著增加幼嫩插穗的侧根数、侧根长度、茎粗,其中以浸泡浓度20mg·L-1、浸泡2h效果最好,浓度超过20mg·L-1、浸泡2h会产生抑制作用。The bottom of the stem of Aster is soaked in GGR6 plant growth regulator solution.The soaking periods are 1 h,2 h and 4 h respectively,the soaking concentrations of GGR6 are 10 mg·L^(-1),20 mg·L^(-1) and 30 mg·L^(-1).The result shows that the root numbers,stem height and diameter of stem all increast obviously.Especially a combination of 2 h soaking period and 20 mg·L^(-1) concentration brings the best (effect).When the concentration of GGR6 exceeds 20 mg·L^(-1) and the soaking period exceeds 2 h,inhibition appear in the experiment.
