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.

A method and a device for propagating plants, by which the propagation rate or growth rate of the plants can be increased. This is achieved in that at least one plant is recorded at least in regions by an image recognition device and plant-specific features of the at least one plant are recognized by a control unit on the basis of the items of information obtained by the image recognition device. In dependence on the recognized features, at least one component of the plant is then automatically severed from the plant by a cutting means for propagation. A type and/or physical properties of the cutting means to increase a propagation rate of the plants are selected in accordance with the recognized plant-specific features of the plant.

The application provides a method for improving nutrient supply of female floral branches of Populus deltoides artificial hybridization. According to the technical links of the hybridization operation, the method separately integrates and improves the cultivation of female floral branch nutrient-supply seedlings (i.e., grafting rootstocks of floral branches), the pre-management of female floral branch nutrient-supply seedlings, the hydroponic management of floral branches, the Marching between female floral branches and rootstocks, the management of female floral branch nutrient-supply seedlings and the hydroponic management of female floral branches, so the goal of improving the seed-setting rate and quality of poplar hybrid seeds which came from the floral branches cultured in water has been achieved. Compared with the conventional method, the method of the invention not only can realize good seed quality, but also improve the seed-setting rate, and has a remarkable effect when applied to Populus deltoides artificial hybridization.

The present invention is a single blade clone cutter. The single blade clone cutter comprises a u-shaped housing with a single removable blade. The blade is locked into the u-shaped housing to secure the blade from moving during the process of cutting. It is important to have a single blade that cuts onto a flat surface so there is no damage being done to the fibers at the end of a cutting.
