红叶石楠“鲁宾斯”扦插育苗技术初探

Studies on Cuttage Propagation of Photinia glabra 'Rubens'

以当年生红叶石楠“鲁宾斯”半木质化枝条为扦插材料，进行4因素3水平正交试验，探明试验药剂浓度、插穗浸泡时间、插穗长度等因素对红叶石楠“鲁宾斯”的生根率、平均根数、平均根长的影响；以寻找各因素各水平之间的关系及最佳组合。结果表明：红叶石楠“鲁宾斯”的扦插育苗，以ABT生根粉浓度为100mg／L，插穗长度为10-15cm，插穗浸泡时间为2—3h，枝条部位取中部至基部为好。

Taking semi - lignified branches as cutting material, an orthogonal cuttage experiment of Photinia glabra ＂Rubens＂ was designed with four factors and three levels to determine the plant growth regulator concentration, the soaking time duration, the cuttage length and other technical parameters. The rooting rate, the mean root number and the mean length of the new roots were measured and the relations among the above factors as well as the optimal combination were studied. The results showed that the best combination for optimal P. glabra ＂ Rubens＂ cuttage propagation was taking 100 mg/L of ABT, 10 -15 cm long cuttings prepared with the middle to basal part of the semi - lignified branches and soaking the cuttings in the ABT solution for 2 - 3 h before operation.
