林业公益性行业科研专项经费“金银花、凹叶厚朴新品种创制及利用技术研究”（201104023）；

本校为第一机构

为了探索凹叶厚朴扦插生根的方法及其生根机理,促进凹叶厚朴优良无性系的快速推广栽培。以半木质化枝条为插条,依据单因素试验结果,设计L_9(3~4)正交试验,优化扦插生根配方;定期采集插条下段,测定其韧皮部内的营养物质的含量及氧化酶的活性变化;定期采集插穗下部制作石蜡切片,观察生根部位及发生过程。凹叶厚朴的最佳扦插生根配方为:以泥炭土:珍珠岩:黄沙(1:1:1)为基质,用KIB A1000mg/L浸泡30min,生根率可达94.4%;生根过程中,用KIBA浸泡的插条与对照相比,其内的营养物质含量及PPO及POD活性的变化规律相同,但试验组各项峰值到达的时间比要对照早10天,对应的生根时间也早10天;PPO及POD活性最高值达...

The aims were to explore the cutting rooting method and rooting mechanism of Magnolia offieinalischanges of oxidase activity in the phloem; produced the cuttings paraffin sections to observe the rooting location and process. The best rooting formula of M. officinalis subsp. Biloba was as follows： matrix of peat soil：perlite：sand （1：1：1） processed with KIBA 1000 mg/L for 30 min, the rooting rate was up to 94.4%; compared the cuttings immersed with KIBA with the control, the variation regularity of nutrient contents and the activity of PPO...
