摘　　要：以鸡树条、台东荚蒾、蝴蝶戏珠花、金佛山荚蒾和日本珊瑚树当年生半木质化枝条作为试验材料,研究ABT1不同浓度和不同处理时间对其嫩枝扦插生根效果的影响。结果显示,鸡树条、台东荚蒾、蝴蝶戏珠花、金佛山荚蒾和日本珊瑚树5种植物生根能力有所差异,且不同树种的最适生长调节剂处理浓度和时间不同。其中,ABT1高浓度速蘸或低浓度浸泡均可有效促进鸡树条和日本珊瑚树生根,生根率高达90%以上。台东荚蒾插穗生根最适处理为ABT11000 mg/L速蘸30 s或100 mg/L浸泡2.0 h,生根率分别为95.96%、98.04%,不定根数量分别为25.27、21.47条,最长不定根长分别为7.51、8.37 cm。金佛山荚蒾插穗生根最适处理为1000 mg/L速蘸30 s,生根率达83.95%,不定根数量为26.13条,最长不定根长为8.19 cm。蝴蝶戏珠花插穗ABT1100 mg/L浸泡0.5 h处理下,整体生根效果最佳,生根率为31.86%,不定根数量为27.67条,最长不定根长为7.38 cm。由隶属函数综合评价结果可知,日本珊瑚树的平均隶属函数值最大(0.74),生根效果最好,其次依次是台东荚蒾(0.70)、金佛山荚蒾(0.42)和鸡树条(0.38),蝴蝶戏珠花均值最小(0.33),生根效果最差。The effects of different concentrations and different treatment time of ABT1 on the rooting of semi-lignified branches of V.opulus subsp.calvescens,V.taitoense,V.plicatum f.tomentosum,V.chinshanense and V.odoratissimum var.awabuki were studied.The results showed that there were differences in rooting capacity among the five plants,and the optimal growth regulator concentration and time were different among the species.ABT1 high-concentration rapid dipping for 30 s or low-concentration soaking can effectively promote the rooting of V.opulus subsp.calvescens and V.odoratissimum var.awabuki,and the rooting rate was as high as 90%.The optimum rooting treatment for V.taitoense cuttings was ABT11000 mg/L dipping for 30 s or 100 mg/L soaking for 2.0 h.The rooting rates were 95.96%and 98.04%,the number of adventitious roots was 25.27 and 21.47,and the longest adventitious root lengths were 7.51 cm and 8.37 cm,respectively.The optimal rooting treatment for V.chinshanense cuttings was 1000 mg/L rapid dipping for 30 s,while the rooting rate was 83.95%,the number of adventitious roots was 26.13,and the longest adventitious root length was 8.19 cm.The comprehensive rooting effect of V.odoratissimum var.awabuki was the best under the treatment of ABT1100 mg/L soaking for 0.5 h,with the rooting rate of 31.86%,the adventitious roots number of 27.67,and the longest adventitious root length of 7.38 cm.The rooting ability of V.opulus subsp.calvescens,V.taitoense,V.plicatum f.tomentosum,V.chinshanense and V.odoratissimum var.awabuki was evaluated by menmbership function method.The results showed that the average membership function value of V.odoratissimum var.awabuki was the highest(0.74),and the rooting effect was the best,followed by V.taitoense(0.70),V.chinshanense(0.42),and V.opulus subsp.calvescens(0.38),the mean value of V.plicatum f.tomentosum(0.33)was the lowest,and the rooting effect was the worst.
