用生根剂浸泡后,插穗掉叶相对集中于插后30天内;60天后开始形成愈伤组织和生根发芽,180天后根系已初步形成、芽叶迅速生长。对于12h 和6h 处理,生根剂浸泡五棱苦丁茶插穗的时间越长,对插穗叶的影响越大,却有利于插穗愈伤组织的形成和根系生长发育;就50mg/L(10g/L)、100mg/L(5g/L)两种浓度而言,前者的综合表现好于后者;在本试验所采用的5种生根荆中,ABT、BR、SY 三种生根剂处理的效果优于 IAA、NAA,但不如这几种生根剂的混合液。
After soaking with rooting agent, the cut leaves of the cuttings were relatively concentrated within 30 days after inoculation; the callus began to form after 60 days and the rooting occurred. After 180 days, the root system was initially formed and the shoots grew rapidly. For 12 h and 6 h treatments, the longer rhizome dipped the cuttings of G. pentaphyllum, the greater the effect on the cut leaves, but it was conducive to the callus formation and root growth of cuttings. For 50 mg / L (10 g / L ) And 100mg / L (5g / L), the comprehensive performance of the former is better than that of the latter. Among the five kinds of Radix et Rhizoma Zingiber officinale used in this experiment, the effects of three rooting agents ABT, BR and SY are excellent In IAA, NAA, but not as good as these kinds of rooting agent mixture.
