摘　　要：为探讨不同基质和生长调节剂对山茶扦插生根的作用,本试验以山茶品种‘金盘荔枝’嫩枝为插穗,分别研究3种不同基质类型(河沙、珍珠岩以及园土+河沙)和3种生长调节剂处理(NAA、IBA和ABT-1号)对山茶扦插生根的影响。结果表明,园土+河沙作为基质的山茶扦插生根率最高,珍珠岩作为基质的山茶扦插生根率最低;3种基质下的山茶插穗生根指数和根系生物量干质量均表现为园土+河沙>河沙>珍珠岩。3种生长调节剂处理下,IBA处理下不定根数量最多,NAA处理下不定根数量最少,IBA处理下插穗的平均根长最长,ABT-1号处理下插穗的最长根长最长,各处理对山茶扦插的生根指数和根系生物量干质量表现一致,均为ABT-1号>IBA>NAA>CK。In order to probe the different substrates and growth regulators on cutting propagation of Camellia japonica,the effects of 3 different types substrates(river sand,perlite,garden soil+river sand)and 3 different types growth regulators(NAA,IBA,ABT-1)on cutting propagation were investigated with the tender branches of C.japonica‘Jinpanlizhi’.Results showed that the rooting rates of the cuttings with the substrate of garden soil+river sand were the highest,while the rooting rates of the cuttings with the substrate of perlite were the lowest.The order of rooting index and root biomass of C.japonica with 3 different types substrates was garden soil+river sand>river sand>perlite.IBA treatment had the highest amount of rooting.NAA treatment had the lowest amount of rooting.IBA treatment had the longest average root length of cuttings.ABT-1 treatment had the longest root length of cuttings.The rooting index and root biomass of C.japonica cuttings were all consistent,the order of rooting index and root biomass of C.japonica cuttings with 3 differen types growth regulators was ABT-1>IBA>NAA>CK.
