摘要：In this paper, to identify a utilization direction for the processing waste of dracaena sanderiana and improve the rooting rate of myrtle cuttings, with rooting rate, average number of roots and average root length as rooting indicators, we discussed the effects of D. sanderiana extract, different concentrations, IAA and other factors on the rooting of myrtle cuttings. The results showed that D. sanderiana aqueous extract had a comparable rooting-promoting effect to that of IAA and suggested that a rooting-promoting substance existed in D. sanderiana extract, which can provide an experimental technical support for a cheap, non-toxic and effective specialized rooting agent for myrtle, as well as the cutting breeding of myrtle.
