摘　　要：全光喷雾条件下进行了不同基质、不同长度(下端节到剪口)、不同的剪口形状的菊花(Dendranthemamorifolium(Ramat)Tzvel.)扦插试验。结果表明,蛭石基质中菊花插穗的平均发根数极显著高于河沙和育苗土(P<0.01),河沙基质的插穗平均最长根长极显著高于育苗土(P<0.01),蛭石和育苗土的生根率极显著高于河沙(P<0.01)。不同的长度(下端节到剪口)插穗的平均发根数、平均最长根长和生根率均无显著差异(P>0.05):平口与斜口之间的最长根长有显著性差异(P<0.05)。插穗的根长和发根数存在着线性关系,其回归方程为y=5.516+0.208x。Under the condition of full—light spray,cutting experiment of Dendranthema morifolium was carried out with the different medium,different length of cuttings and the different cut shapes. Results showed that the average number of roots inVermiculite stroma is more than the roots in sand stroma and Nursery soil（P〈0.01）and average root length in sand stroma is significantly longer than that in Vermiculite and Nursery soil（P〈0.01） There is no difference of the average number of roots generated,average longest root length and average rooting among different cutting length（P〉0.05）. Transversely cut and slanting cut has remarkable effect on the root length.The root length and root number has linear relation and the regress equation is y = 5.516 ＋ 0.208x.
