Abstract: Soilless cuttage rooting is accelerated under the conditions of temperature and humidity automatically controlling in silkworm egg incubation room with the cuttings that had been cut from the annual branches of 4 mulberry varieties, cold stored for 20 days and treated with ABT rooting powder and indole acetic acid solution. The rooting rate and root number per cutting of all the varieties is more than 80% and 25, although there is significant difference among the mulberry varieties and treatment reagents. Most of the rooted cuttings survived after transplanting in nursery as the new roots broke out from the cortices.
