Method for culturing submerged plant seeds

Abstract

The invention relates to a method for culturing submerged plant seeds. The method comprises the following steps: A, soaking the submerged plant seeds produced by apomixia in 0.01-1wt% of dimethoate or sodium hypochlorite solution for 1-6 hours, washing the soaked submerged plant seeds with clear water, naturally drying the soaked submerged plant seeds in the air; B, standing the submerged plant seeds at 20-25 DEG C for 1-3 days, storing at 1-5 DEG C for 1-2 days, and preserving at 30-40 DEG C for 12-36 hours; C, soaking the submerged plant seeds in solution containing plant hormone, trace elements and inorganic salt for 12-24 hours; and D, burying the submerged plant seeds in a matrix by a depth of 3-5cm, and then putting the matrix in which the submerged plant seeds are buried at the bottom of river or lake water. The matrix comprises humus, sediment at the bottom of river and lake, bank soil, clay and sand. The submerged plant seeds bred by the method have high germination rate and environmental adaptability.

Description

Technical field

[0001] The invention relates to a method for breeding submerged plants, in particular to a method for breeding apomictic seeds of submerged plants. Background technique

[0002] Submerged plants refer to large-shaped aquatic plants that live steadily under the water layer. Their roots are somewhat underdeveloped or degraded, and all parts of the plant can absorb water and nutrients, and the aeration tissues are particularly developed, which is conducive to gas exchange in the absence of air in the water. Most of the leaves of this kind of plants are ribbon-shaped or filamentous, such as bitter grass, hornwort, myriophyllum, black algae and so on.

[0003] Submerged plants are the main primary producers of aquatic ecosystems and occupy an important ecological position in the biological chain. Submerged plants provide more habitats and shelters for aquatic animals, expand the effective living space of aquatic animals, and the young parts of plants can be eaten by aq...
