The germination rate of vegetable seeds has a great relationship with the age of storage. The variety of vegetables varies from year to year.
Tomato: It can be stored for 3-4 years, and the longest is no more than 4 years. Otherwise, the bud rate will be reduced. The method of identifying new and old seeds is that the new seeds have hairy hair and tomato flavor. The old seed coat has less hair or falls off.
Cucumber: It can be stored for up to 2-3 years. After this period, the germination rate is generally reduced by 20-30%. Even if it can be emerged, some often have no true leaves after emergence and are not easy to survive.
Eggplant: The seeds can be used for storage within 6 years. The new seed coat is shiny, and the old seeds are reduced in luster according to the storage period.
Pepper: Can not exceed 3 years, otherwise the bud rate is reduced, the bud rate stored for 2 years is reduced by about 10%, the storage is reduced by about 30% for three years, the new seed is golden yellow, and the young seed is apricot.
Onion seeds: In the summer, the onion must be used in the new seeds of the year. If the seeds are aged, the shallots will be sowed with seeds. The spring onions can be used to produce seeds from the first year.
Coriander: Must be stored for one year before use, but not for more than 3 years. Otherwise the fragrance becomes smaller.
Celery: can be stored for 3 years, the seeds of the year can not be used, must be stored after one year.
Amaranth: The new seed is good in the year, and the germination rate is greatly reduced if stored for two years.
Cabbage: It can be stored for two years. The seeds harvested in the same year can be sown in the same year, but if it is more than two years, the emergence rate is reduced by 20-30%, and the disease resistance is low.
