云南红豆杉扦插繁殖技术研究

Cutting Propagation Technology of Taxus yunnanensis

对云南红豆杉进行扦插繁殖试验研究,结果表明:云南红豆杉扦插育苗应选择半木质化的当年新枝作为插条生根率最高;在丽江市境内适宜云南红豆杉扦插的时间较宽,其中最佳扦插时间为7月和8月;用生根促进剂ABT2号生根粉进行插条处理的最佳浓度为200 mg/L;ABT2号生根粉是云南红豆杉扦插的最佳生根促进剂。

Cutting propagation technology of Taxus yunnanensis was conducted. The results showed that current year shoot of semi-lignified cuttings had highest rooted ratio. Suitable cutting time for Taxus yunnanensis was wide in Lijing, and the most suitable time were in July and August. The optimum concentration of ABT NO2 to deal with cuttings was 200 mg/L, and ABT No2 was the best rooting accelerating agent for Taxus yunnanensis.
