摘要/Abstract

摘要： 研究了牡丹矮生品种‘银粉金鳞’、‘蓝田玉’、‘金玉交章’、‘小胡红’和‘石原白’黄化嫩枝扦插繁殖的关键环节和影响因素。结果表明, 该5 个品种黄化嫩枝生根率依次为91.0%、80.9%、78.6%、40.6%、20.0%; 于10月中旬截取长4～6 cm、基部直径0.5 cm以上的黄化嫩枝, 将形态学下端浸泡在20～25℃的IBA 100 mg/L或‘ABT 2号’150 mg/L中16 h, 扦插于粒径3～4 mm的蛭石基质里,‘银粉金鳞’插穗的生根率最高, 达93% , 且不定根健壮、上盆栽培生长良好。

Abstract: This paper is of propagation of etiolated softwood cuttings from five cultivars of dwarf Chinese tree peony, ‘Yinfen Jinlin’, ‘Lantianyu’, ‘Jinyu Jiaozhang’, ‘Xiaohuhong’, and ‘Shiyuanbai’, respectively. As the results, rooting rates of five cultivars mentioned above are 91.0% , 80.9% , 78.6% ,40.6% , 20.0% , respectively. The etiolated softwood cuttings with 4 - 6 cm length and 0.5 cm thicker in diameterwere taken in the middle of October, emerged their bases in the rooting promoter solution, IBA 100 mg/L or‘ABT 2’150 mg/L for 16 h at 20 - 25 ℃, inserted into the cutting bed of vermiculate with particle of 3 - 4 mm in diameter. The highest rooting rate of 93% was achieved for the cultivar‘Yinfen Jinlin’. Adventitious roots occurred were strong and young plants grew well after transp lanted them into pots.
