Embodiment

[0028] 5000 ml of normal sea water (34 psu) was filter sterilized. Randomly select 1000 eelgrass seeds, put them into jars filled with sterilized seawater with a salinity of 34 psu, seal them, and place them at a temperature of 0°C. Carry out once a week iso-salinity sterilized seawater replacement, check the condition of seeds every 2 months, count the germinated seeds, and randomly select ungerminated eelgrass seeds for seed activity test (germination test), the duration is 13 months moon. Table 1 shows the records of eelgrass seed retention rate and seedling establishment rate under the conditions of salinity value 34psu and temperature 0°C.

Abstract

The invention relates to a preservation method of seeds, in particular to a method for prolonging the preservation time of eelgrass seeds. The method comprises the following steps: filtering common natural seawater, and then sterilizing the seawater; directly putting the washed eelgrass seeds into a sealed container with the sterilized seawater; keeping the temperature of the seawater in which the eelgrass seeds are soaked at -0.2 to 0.2 DEG C; in the preservation process of the seeds, regularly exchanging water. According to the method for prolonging the preservation time of the eelgrass seeds, the retention rate in the preservation period of the eelgrass seeds can be increased, and the preservation time of the seeds is prolonged; meanwhile, relatively high vitality and quality of the seeds can be maintained; furthermore, the survival rate of eelgrass seedlings is increased; by the combination of the simple and effective eelgrass seed preservation method, high-quality eelgrass seeds and healthy seedlings can be provided for manual sowing, recovery or reconstruction of an eelgrass sea grass bed is facilitated, and a foundation support is supplied to quick recovery of a good ocean ecological environment; moreover, by the use of the sterilized common seawater for preservation, the method is convenient, simple, practical and cost-saving.

Description

technical field [0001] The invention relates to a seed preservation method, in particular to a method for prolonging the preservation time of eelgrass seeds. Background technique [0002] Seagrass meadows ecosystem, mangrove forest and coral reef ecosystem are considered to be three typical offshore marine ecosystems. And international research results show that the ecological service value of seagrass fields is significantly higher than that of mangroves and coral reefs. The "seaweed" mentioned here refers to the only angiosperm submerged in shallow sea water, which differentiates into organs such as roots, stems, leaves, flowers and seeds, and "seaweed" as lower plants (such as kelp, enteromorpha, etc.) very different. [0003] Lush seagrass fields are like forests on land, an important symbol of a healthy marine environment, and are precious "undersea grasslands" or "undersea forests". Seagrass fields are high-productivity areas that can provide good habitats, nursery ...
