A method for disinfecting explants of Kadsura coccinea stems with buds and a method for directly inducing rapid proliferation of sterile buds by using the explants of Kadsura coccinea stems with buds involve processes such as selection, treatment and disinfection of explants, primary culture, subculture proliferation culture. The problem of difficulty in tissue culture and primary culture of Kadsura coccinea stems is solved, and the advantages include low contamination rate of explants, high propagation rate and robust proliferation of axillary buds. This allows obtaining sterile axillary buds of Kadsura coccinea through tissue culture, and provides support for tissue culture, rapid propagation and factory seedling of Kadsura coccinea in the future.

The present invention provides culture apparatus for a plant whole body and a method for culture of such a plant whole body, which allow liquid-phase roots and vapor-phase roots to separately appear in the root system without using soil. More specifically, a plant whole body is cultured by using culture apparatus for a plant whole body, which comprises a container constructed with a structure showing capillary force; and a basin holding liquid.

The present disclosure describes a method of culturing and harvesting plant shoot tips. The method includes providing a sterile vessel configured to hold at least one plant with one or more root masses and a first set of shoot tips, cutting across a base of the shoot tips with the one or more root masses held in the vessel to cut a first plurality of cut shoot tips at a first time; then growing a second set of shoot tips from the one or more root masses in the vessel; and then cutting across the one or more root masses held in the vessel to cut a second plurality of cut shoot tips. Plant tissue culture devices are also described.

The present description relates to a plant cutting device for cutting or cloning a plant, and housing the plant for growth. The plant cutting device generally comprises two compartments that are operatively connected together and displaceable from an open position to a closed position defining an enclosure, a cutter mounted within at least one of the compartments and configured to cut a plant part when the first and second compartments are displaced to the closed position, a cut end of the plant part being accommodated within the enclosure; and a growth medium disposed in the first compartment and/or the second compartment for contacting the cut end of the plant part allowing for the growth of the plant.
