Toxin-free seedling production method suitable for fast propagation of submerged plants

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...

Problems solved by technology

[0005] CN102204484A discloses a method for propagating and cultivating submerged plants, which adopts the method of directly cultivating submerged plants in large-scale devices in the field, and the survival rate is not mentioned;

Therefore, it is necessary to find a new path to avoid the disadvantages of the quality reduction of non-virus-free cuttings, the high cost of single-species culture methods, and the transplantation damage of tissue-cultured aseptic seedlings.
