探索了两种不同生长素萘乙酸(NAA)和吲哚丁酸(IBA)对含笑(Michelia figo)水中扦插插穗生根的影响。NAA和IBA各设置3个质量浓度梯度,即1、3、5 mg/L,以清水为对照;设置2、4、6 h 3个时间水平,对含笑插穗进行处理。结果表明:NAA和IBA均在质量浓度为3 mg/L时对插穗生根时间、生根率、生根数效果最好,而处理时间却影响不大。
The effects of NAA and IBA on the rooting of cutting cuttings in Michelia figo water were explored. NAA and IBA each set three mass concentration gradient, namely 1,3,5 mg / L, with water as a control; set 2,4,6 h three time levels, to deal with smiling cuttings. The results showed that both NAA and IBA had the best effect on the rooting time, rooting rate and rooting number of cuttings at the concentration of 3 mg / L, while the treatment time had no significant effect.
