Abstract

The invention provides a seedling hardening method and a seedling transplanting method for a hybrid test-tube plantlet, and relates to the technical field of plant engineering. The seedling hardening method comprises:culturing a hybrid test-tube plantlet in an aseptic culture vessel until the test-tube plantlet grows to the height of 4-6 mm and grows at least three adventitious roots, breaking the aseptic environment of the culture vessel, enabling the test-tube plantlet to continue to grow until the surface of a culture medium in the culture vessel becomes turbid, and finishing seedlinghardening. The transplanting method comprises:taking out the hybrid test-tube plantlet from the culture vessel together with the culture medium, cleaning the culture medium at the root part with clean water, planting in a sterilized growth matrix, setting different conditions in a culture room according to different growth stages, and continuing to culture. The provided seedling hardening method and the seedling transplanting method for the hybrid test-tube plantlet effectively improve the survival rate of the hybrid test-tube plantlet, and save the time cost and the labor cost.

Description

technical field [0001] The invention relates to the technical field of plant engineering, in particular to a method for hardening and transplanting hybrid test-tube seedlings. Background technique [0002] Hybridization between different species, genus or species with more distant relationship in plant taxonomy is usually called distant hybridization. As a breeding method, distant hybridization breaks the boundaries between species, artificially promotes the exchange and combination of genetic material between different species, and combines the unique traits of different biological types into a common hybrid individual to varying degrees in order to create new species. Therefore, it plays an important role in the research of plant genetics and breeding, and has received long-term attention from genetic and breeding experts. Its application in breeding mainly includes the artificial creation of new species, the improvement of stress resistance of varieties, the creation of...
