The invention discloses an open-type cold region Chinese rose
tissue culture seedling propagation method, which is characterized in that parachlorometaxylenol and
miconazole nitrate are used as bacteriostatic agents and are respectively applied to
tissue culture links such as explant earlier-stage treatment, appliance sterilization, culture medium preparation, explant disinfection,
tissue culture seedling transplanting and the like, so that the propagation process of the cold region Chinese rose tissue culture
seedling gets rid of environmental limitation. Explant disinfection does not need a strict
sterile environment, a high-pressure sterilization pot and an ultra-clean
workbench are not used, and rapid breeding of Chinese rose tissue culture seedlings is achieved. Compared with a conventional sterilization method, the induction rate of the cluster buds is remarkably improved, and the
pollution rate, the
vitrification rate and the
browning rate are remarkably reduced. The growth vigor of the tissue culture seedlings after rooting is obviously improved; and particularly, the effects of Hanjin No.1 and Changbai Mountain
vine roses are prominent.
