Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0054] In the present invention, the jointed stems, buds and rhizomes of submerged plants are used as explants, and through the rapid multiplication method of non-callus culture, the formula of the medium is adjusted for different species, and a variety of submerged plants are produced on a large scale. Plant detoxification high-quality seedlings, including the following steps: remove the apical advantage, explant cutting, explant disinfection, activation of lateral meristems, induction of complete seedlings, strong s...

Abstract

The invention discloses a toxin-free seedling production method suitable for fast propagation of submerged plants. The toxin-free seedling production method suitable for fast propagation of the submerged plants comprises the following steps: eliminating apical dominance; cutting explants; disinfecting the explants; activating lateral meristems; inducing complete seedlings; strengthening the seedlings; and packaging engineering seedlings. The toxin-free seedling production method suitable for fast propagation of the submerged plants is suitable for multiple kinds of submerged plants, with stemswith joints, bud segments and rhizomes of the submerged plants applied as the explants, through non-callus culture and fast propagation, the production cost is reduced, a culture medium formula is adjusted for different species, high-quality toxin-free seedlings of the multiple kinds of submerged plants are subjected to scale production, the requirements of diversity of species in an aquatic ecological environment are met, and the high-quality toxin-free seedlings of the multiple kinds of submerged plants have effects in the aspects of ecological environment construction, comprehensive treatment of water environments and wetland rejuvenation engineering.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to a method for producing detoxified seedlings suitable for rapid propagation of submerged plants, which meets the needs of wetland water environment control and water ecological restoration projects for high-quality seedlings of various submerged plants. need. Background technique [0002] Submerged plants refer to a type of large-scale aquatic plants that are submerged under the water surface. The common types of submerged plants include bitter grass, black algae, hypophyllum verticillium, eye vegetable, elodea, hornwort and foxtail algae. Wait. As the main primary producers, submerged plants are an important part of the food chain in the aquatic ecosystem and have important ecological functions. Submerged plants can fix the sediment, purify the water body, absorb suspended solids, reduce turbidity, and provide water for aquatic animals. Food and habitat, can also i...
