摘要/Abstract

摘要： 采用L₉（3⁴）正交试验法,研究不同基质、生长素类型以及新梢枝段对亮叶忍冬（Lonicera nitida ‘Maigrun’）嫩枝扦插繁殖效果的影响。对扦插成活率、生根数、根系总长度、根鲜重、新梢数、新梢总长度、新梢鲜重等指标进行了测定分析,结果表明：以河沙或珍珠岩为扦插基质时,各测定指标均极显著高于草炭处理; 吲哚丁酸（IBA）或萘乙酸和吲哚丁酸等量混合液（N+I）处理的扦插成活率极显著高于萘乙酸（NAA）处理,其它各指标则均无显著差异;以新梢基部段位为插条时,生根数极显著高于其它枝段,基部和中部枝段为插条的新梢总长度和新梢鲜重极显著高于梢部,其余各测定指标在不同枝段间的差异不显著。综合各测定指标,进行亮叶忍冬嫩枝扦插繁殖时,以河沙或珍珠岩为扦插基质,采用亮叶忍冬新梢基部或中部段位作为插条,经浓度为1 000 mg•L^-1吲哚丁酸和萘乙酸等量混合液（N+I）或吲哚丁酸（IBA）处理,可获得较高成活率（70%以上）以及较高质量的扦插苗。

Abstract: ：The effects of different matrixes, auxin treatments and shoot sections on the softwood cutting propagation of Lonicera nitida ‘Maigrun’ were studied with the orthogonal design L₉（3⁴）. The indicators including the survival rate, root number, total root length, root fresh weight, shoot number, total shoot length and shoot fresh weight were determined in the experiment. The results show that all examined indicators by using sand or perlite as cutting media were significantly higher than that by using peat, the survival rate in the treatment with IBA or NAA+IBA behaved significantly higher than that with NAA in the all indicators measured, the rooting number produced from the basal section cuttings was significantly higher than that from other sections cuttings, the total shoot length and shoot fresh weight derived from basal and middle section cuttings showed significantly higher than those from the terminal section, and there was no significant difference between other indicators in the different shoot section treatments. According to the multiple analysis, higher cutting survival rate（above 70%）and high quality young cutting plants can be obtained in the cutting propagation of Lonicera nitidat ‘Maigrun’ by using the sand or perlite as cutting media, middle or basal shoot section as cuttings, and using equal mixture liquid of IBA and NAA in the concentration of 1 000 mg·L^-1to dip the cuttings.

Key words: Lonicera nitida ‘Maigrun’, softwood cutting, matrix, auxin, shoot section
