Embodiment 1
[0031] Use distilled water and seawater to prepare 2000 milliliters of artificial seawater with a salinity of 10, 20, 30, 40, 50 and 60 respectively. The prepared artificial seawater was sterilized and placed in 12 1000ml wide-mouth glass bottles respectively. Randomly select 12,000 R. sinensis seeds, put them equally into jars filled with the above-mentioned sterilized seawater with different salinities, seal them, and place them at 0 or 4°C respectively. The seeds can be stored for 9 months. During the period, the sterilized artificial seawater with equal salinity and corresponding temperature was replaced once a month (that is, the artificial seawater placed at 0°C was still at 0°C), and the status of the seeds was checked every 3 months, and the germinated seeds were counted and recorded. Randomly select the ungerminated seeds of G. siberiani for seed viability test (germination experiment: 150 seeds are randomly taken out from each preservation experiment group, divided ...
