摘要
以“紫香1号”和“黄金果”为材料,以砂壤土、园土、营养土、清水等为扦插基质,以当年生茎的上段、中段、下段等为插条,以IBA和生根粉等生长调节剂处理插条,研究不同品种、不同基质、不同插条、生长调节剂对西番莲扦插生根率、生根质量的影响。结果表明,“紫香1号”与“黄金果”的扦插生根率均较高,但“紫香1号”根系生长情况明显优于“黄金果”,且成活率高;以园土为生根基质的生根率最高,达86.7%,以砂壤土为扦插基质时根系最发达;以中段作为插条时生根率最高,根系生长情况最好;以10 mg/L IBA浸泡处理插条55 min和生根粉处理35 min时,插条根系生长情况最优。
Effects of different varieties,substrates,cuttings and growth regulators on the rooting rate and rooting quality of Passiflora were studied by using‘Zixiang No.1’and‘Huangjinguo’as materials,sandy loam,garden soil,nutrient soils and water as cutting substrates,the upper,middle and lower segments of the current year’s stems as cuttings,IBA and rooting powder as growth regulators.The results showed that the rooting rate of‘Zixiang No.1’and‘Huangjinguo’was very high,however,the root growth of‘Zixiang No.1’was obviously better than that of‘Huangjinguo’and its survival rate was also higher.The rooting rate was the highest when the garden soils were used as cutting substrates,reaching 86.7%,yet the growth of roots was the best when the sandy loam was used as substrates.The rooting rate and root growth of the middle segment cuttings were better than that of upper and lower segment cuttings.The root growth was the best when the cuttings were soaked in 10 mg/L IBA for 55 min and treated with rooting powder for 35 min,respectively.
