- 摘要:
- 以秦岭野生美容杜鹃为试材，研究ABT-6（生根粉）与IBA(吲哚丁酸)不同浓度对美容杜鹃嫩枝扦插的影响，以及3种不同基质配方中扦插生根率的差异。结果表明：ABT-6的处理中，100 mg/L的插穗生根率最高，IBA的处理中，200 mg/L的插穗生根率最高；在草炭∶蛭石=1∶1的基质中美容杜鹃扦插生长速度最快、生根率最高，纯草炭的生根率最低。同时还得出插穗顶端叶芽与地下切面的生长变化过程为插穗顶端叶芽第15天长出叶尖，第30天叶片成熟；地下切面第20天长出愈伤组织，第30天长出小根。
- Abstract:
- Using Qinling wild Rhododendron calophytum as experiment material，the effect of different solution of ABT-6 and IBA and three matrixes on rooting rate in wild rhododendron calophytum of Qinling Rhododendron calophytum was studied.The results showed that,100 mg/L ABT-6 and 200 mg/L IBA induced greatest number of roots.The wild Rhododendron calophytum treated with grass carbon and commensurable vermiculite had the highest rate of rooting,the pure grass carbon was lowest inversely.And the growth process was also observed with the aboveground and unserground part,leaf apex was sprouted from the cutting slips in 15 days,and the leaf was matured in 30 days.In addition,callus in transverse section and roots with underground part was formed in 20 and 30 days,respectively.
