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。
The IAA solution with different concentrations (100 mol / L, 300 mol / L, 500 mol / L) was treated with different concentrations of indole acetic acid and different treatment time The effects of rooting rate, rooting amount, root growth rate, root length, callus rooting rate and rooting rate of cuticle on the cuttage rooting rate of five leaves were analyzed. influences. The results showed that the rooting rate of cuttings from F. quinquefasciatus was significantly higher than that of the control under the treatments of different treatment time and different concentrations. Under the condition of IAA concentration of 300 mol / L and treatment time of 1 h, The best growth rate, the highest rooting rate of cuttings, the results can be used as the Rhizoma Dioscorea Indole acetic acid after treatment rooted influence and reference.
