| 摘 要： | 【目的】为提高忍冬科(Lonicera)植物在兰州地区的扦插成活率,缩短其生根时间和育苗周期.【方法】以3种忍冬科植物为材料,研究不同质量浓度(50、100 mg/L)下3种植物生长调节剂吲哚乙酸(IAA)、吲哚丁酸(IBA)和萘乙酸(NAA)在不同处理时间(30、60min)对其扦插生根的影响.【结果】IAA和IBA对天目琼花生根率的影响最大,对金叶接骨木生根数量的促进作用最大,对天目琼花和蓝叶忍冬根的伸长具有抑制作用.NAA对金叶接骨木、天目琼花、蓝叶忍冬的生根率的促进作用不显著(P0.05),对金叶接骨木和蓝叶忍冬根伸长的促进作用不显著(P0.05),但对天目琼花根的伸长具有显著的促进作用(P0.05).在进行苗木扦插繁殖时,为获得较理想的扦插效果,要根据所采集母条的生长特性在特定的时间采集半木质化的嫩枝,同时选用适当的植物生长调节剂和质量浓度,以提高扦插的成活率.【结论】3种植物生长调节剂对3种忍冬科植物的生根率、生根数量及根长的影响存在差异.

| Abstract: | Objective] To improve cutting survival rate of three Caprifoliaceae plants in Lanzhou region,shorten the rooting time and seedling period.Method] Three Caprifoliaceae plants were chosen as materials to study the influence of three kinds of plant growth regulators (IAA、IBA、IBA) on cutting rooting under different concentrations (50 mg/L,100 mg/L) and treated time (30 min,60 min).Result] Effect of IAA and IBA on rooting rate of Viburnum opulus was the greatest,and the promotion on rooting number of S.canadensis 'Aurea' was the maximum,but they inhibited root extension of Viburnum opulus and Lonicera korolkowii.The promotion of NAA on rooting rate of S.canadensis 'Aurea',Viburnum opulus and Lonicera korolkowii were not significant (P>0.05) and it was also not significant on root elongation of S.canadensis 'Aurea' and Lonicera korolkowii but promoted root elongation of Viburnum opulus significantly (P<0.05).In order to get better cutting effect,it should collect half-lignified twigs within specific time according to the growth characteristics of original twigs and choose proper plant growth regulators and concentration to improve cutting survival rate.Conclusion] Three plant growth regulators had different effects on rooting rate,rooting number and root length of three Caprifoliaceae plants. |
