摘要： 为解决目前国内美国红枫扦插育苗难度较大、苗木稀缺的问题，以红花槭‘夕阳红’新梢为试材，研究了不同激素种类对其扦插生根、发芽、生长和幼苗期光合作用的影响。结果表明，在相同浓度(500 mg/L)、不同植物生长调节剂种类（ABT1#、吲哚丁酸、萘乙酸、吲哚乙酸+萘乙酸）处理下，‘夕阳红’槭扦插的生根、发芽、枝叶生长和光合指标均好于对照，如生根率分别比对照高53.5%、50.1%、41.3%和51.1%，成活率分别比对照高53.5%、49.8%、41.3%和51.2%，新梢长度分别比对照高37.9%、23.4%、16.8%和31.1%，幼苗期叶片净光合速率分别比对照高43.32%、26.87%、24.38%和42.14%。其中以ABT1# 500 mg/L和吲哚乙酸+萘乙酸500 mg/L对‘夕阳红’槭扦插繁殖的生根、发芽、生长和光合作用的效果较好。

Abstract: In order to solve that the cutting seedling was difficulty and was short of the seedlings of American red maple at current domestic, Acer rubrum‘Red Sunset’was used to study the effects of different plant growth regulator treatments on its cutting rooting, sprout, growing and leaf photosynthesis. The results showed that, at the same concentration (500 mg/L), different types of plant growth regulator under processing (ABT1#, IBA, NAA, IAA+NAA), the rooting, sprout, growing and leaf photosynthesis of Acer rubrum‘Red Sunset’were better than CK. For example, the rooting rate was higher 53.5% , 50.1% , 41.3% and 51.1% than CK respectively, the survival rate was higher 53.5%, 49.8%, 41.3% and 51.2% than CK respectively, the branch length was higher 37.9%, 23.4%, 16.8% and 31.1% than CK respectively, Pn was higher 43.32%, 26.87%, 24.38% and 42.14% than CK respectively. The ABT1# 500 mg/L and IAA+NAA 500 mg/L were the best plant growth regulator for Acer rubrum‘Red Sunset’in all the treatments.
