摘    要:对五叶地锦插穗采取不同浓度(100 mol/L、300 mol/L、500 mol/L)IAA溶液、不同时间(1h、2 h)处理,以探究不同浓度的吲哚乙酸和不同处理时间对五叶地锦扦插生根的影响,在通过测定插穗生根率、生根数量、根系生长量、根系长度、愈伤组织生根率、皮部生根率指标,分析不同处理对五叶地锦扦插生根的影响。试验结果显示:在不同处理时间和不同浓度的组合处理下,五叶地锦插穗生根率显著高于对照组,在处理时间为1 h时、IAA浓度为300 mol/L的处理条件下,植株长势最好,插穗生根率最高,研究结果可作为五叶地锦经吲哚乙酸处理后生根影响的借鉴和依据。

关 键 词:五叶地锦  植物激素  扦插  生根

Abstract:To investigate the effect of different concentrations and times on the rooting capacity of Parthenocissus thomsoni cuttings, they were treated by 100 mol/L, 300 mol/L, 500 mol/L IAA for 1 h or 2 h for measuring the rooting percentage of callus and cortex, the increment of root growth, the length of root, the amount of roots and survival rate of cutting. The results showed that the rooting rates of cutting treated by different concentration IAA for different time were higher than the control group, and P. thomsoni cuttings treated by 300 mol/L IAA for 1 h was the best treatment. In this condition, the survival rate of cutting was the highest and plant growth was the best. These results were available for reference as rooting of P. Thomsoni treated by indoleacetic acid.
Keywords:Parthenocissus thomsoni  plant hormone  cutting propagation  rooting
