成年芳樟一叶一芽茎段扦插生根研究

Experiment on Rooting of Cinnamomum camphora var. linaloolifera Cuttings

  • 摘要: 以成年芳樟 Cinnamomum camphora var. linaloolifera当年生半木质化枝条为试验材料,修剪成一叶一芽茎段进行扦插,研究吲哚丁酸( IBA)、扦插基质和扦插时间对芳樟茎段扦插生根的影响。结果表明,采用成年芳樟一叶一芽茎段进行扦插,诱导生根快,生根率较高; IBA对芳樟茎段扦插生根具有显著促进作用,扦插后 35 d时出现不定根,以 3 000 mg·L-1 IBA处理芳樟茎段扦插生根效果昀好,其生根率达 67.67%;扦插基质对芳樟茎段扦插生根及扦插苗生长具有显著影响,红壤土 +草木灰=3∶1是芳樟茎段扦插生根适宜基质,扦插苗在该基质上生长昀好;扦插时间对芳樟茎段扦插生根具有显著影响,以 5月扦插生根效果昀好,其生根率为 63.33%,显著高于 8月和 9月扦插,以 9月扦插生根效果昀差,其生根率仅为 32.33%。

     

    Abstract: Current branches of adult Cinnamomum camphora var. linaloolifera were harvested in May 2018, in Nanchang, Jiangxi province for cuttings with one leaf and one bud. They were treated by different concentration of IBA, in different medium and different cutting time. 2 months later, investigations were conducted on rooting and growth of cuttings. The results showed that IBA could evidently improve rooting of cuttings, which had adventitious root 35 days after treatment, and the optimal concentration of IBA was 3 000 mg·L-1 with rooting rate of 67.67%. Cutting medium had significant effect on rooting and growth of C. camphora var. linaloolifera cuttings, the experiment demonstrated that red soil + plant ash=3:1 had the highest rooting rate and the best growth of cuttings. Cutting time had the best rooting effect in May; the rooting rate was 63.33%, significantly higher than that in August and September.
