摘　　要：为获得月季扦插的最佳繁殖方法,以“阳光玫迪兰”“红色绝代佳人”“绒球门廊”“红五月”“仙境”5个耐寒月季品种为试材,进行扦插繁殖试验,探究不同扦插基质、不同植物生长调节剂和不同部位插穗对其生根率、生根数及根长的影响。结果表明:基质、植物生长调节剂、插穗部位对5种月季的生根率、生根数和根长均有影响。各基质处理间存在显著差异,混合基质(河沙∶蛭石∶羊粪=2∶1∶1)处理的生根率显著高于其它基质,以“绒球门廊”在混合基质上的生根率最高,为80.52%,“阳光玫迪兰”“红色绝代佳人”“红五月”的生根率分别为75.32%、65.73%和61.46%,“仙境”的生根率最低,为33.87%;从根长结果来看,“阳光玫迪兰”“绒球门廊”根长显著高于其他处理,“红色绝代佳人”“红五月”混合基质和泥炭土处理的根长是同效的,但显著高于其他3种基质处理;从根数来看,5个品种的混合基质处理也是显著高于其他处理。不同植物生长调节剂处理下,GGR处理的生根率显著高于其它植物生长调节剂,其中“绒球门廊”经GGR处理后生根率最高达95.62%;IBA处理能明显促进根长生长,与其他激素处理相比差异显著;GGR处理的生根数显著高于其它植物生长调节剂,其中“绒球门廊”生根数最多、达8.35条。不同部位插穗对扦插生根率也有影响,枝条中部作为插穗的扦插生根率、根数高于其他部位,但基部插穗更有利于根长的生长。综合三种因素考虑,认为5个月季品种扦插最佳组合为中部枝条+GRR150 mg·L^(-1)+复合基质。Using five cold resistant varieties of Rosa chinensis,including"Sunshine Midland""Red Unparalleled Beauty""Pony Ball Porch""Red May"and"Wonderland"as materials,conducted cutting propagation experiment,which aimed at the outcomes of the rooting agents,the rooting numbers and the root length under the different cutting propagation substrates,different plant growth regulators and different cutting slips.The results showed that there were differences in the rooting rate,the root number,and the root length among the five Rosa chinensis varieties on different substrates.The rooting rate on the mixed substrate(river sand∶vermiculite∶sheep dung=2∶1∶1)was significantly higher than that on other substrates.Among them,the rooting rates of the"Pony Ball Porch"on the mixed substrate was the highest,reaching 80.52%,while the rooting rates of"Sunshine Midland","Red Unparalleled Beauty",and"Red May"were 75.32%,65.73%,and 61.46%,respectively."Wonderland"was the lowest,only reaching for 33.87%.Besides,in terms of the root length,"Sunshine Midland","Pony Ball Porch"were better than other treatments;"Red Unparalleled Beauty"and"Red May"were the same outcomes under mixed substrates treatment and peat soil treatment,but significantly effective compared with the other three kinds of treatments.Lastly,in terms of the root number,the mixed substrate treatment of the five varieties was also significantly higher than the other treatments.Under treatments with different plant growth regulators in five R.chinensis varieties,the rooting rate of"Pony Ball Porch"on GGR is significantly higher than other rooting agents,with the highest rooting rate reaching 95.62%.IBA treatment can significantly promote root growth,compared with other plant growth regulator treatment.The number of roots treated by GGR was significantly higher than that of other plant growth regulators,with the largest number of"Pony Ball Porch"reaching 8.35 individuls;Different cutting slips also has an influence on the rooting rate.The rooting rate of the middle cutting
