    杀菌剂和生长调节剂对九重葛插穗生长和生化指标的影响

    Effects of Fungicides and Growth Regulators on Growth and Biochemical Characteristics of Bougainvillea spectabilis Softwood Cutting

    • 摘要: 用多菌灵 福美双和NAA IBA对九重葛Bougainvillea spectabilis插穗浸泡处理后扦插,测定了插穗的形态生长指标、内源性激素IAA、ABA和可溶性糖含量的动态变化.结果表明:NAA IBA和适宜的多菌灵 福美双均可提高插穗的生根,促进根的生长,成活率显著地高于对照(P<0.01);533 mg·L-1多菌灵 福美双和200 mg·L-1 NAA IBA 处理都提高了插穗叶和插穗基端的IAA和可溶性糖含量,ABA的含量下降.用533 mg·L-1多菌灵 福美双和200 mg·L-1 NAA IBA 分别浸泡插穗1.5 h,成活率达到95.6%,比单独用200 mg·L-1NAA IBA处理的成活率提高了6.67%;NAA IBA对插穗体内物质的运输不利,多菌灵 福美双可促进插穗的物质运输.
