There is a great relationship between the germination rate of vegetables and their years of preservation. Different types of vegetables have different storage ages. Here are some of the dates for the preservation of commonly used vegetable seeds:
Tomato seeds can generally be stored for 3 to 4 years and not longer than 4 years, otherwise it will reduce the germination rate. There are many small hairs on the new seeds, and there is tomato flavor; the Chen seeds have less velvet or shedding, and the smell is also small.
The cucumber seeds are stored for a maximum of 2 to 3 years. The germination rate is generally reduced by 20% to 30% beyond this period. Even if some of them can emerge, they often have no true leaves after emergence and are not easy to survive.
Eggplant seeds can be stored for a longer period of time. Seeds within 6 years are generally available. The new seed has a glossy skin, but the gloss fades as the shelf life increases.
The pepper seeds can not be stored for more than 3 years, otherwise the germination rate will decrease. According to the test, the germination rate of new seeds was over 89%, and the germination rate was about 79.8% after 2 years of storage. The germination rate for storage for 3 years would be reduced by about 47%. The color is golden yellow for the new seed, apricot yellow for Chen seeds.
In summer, the green onions must be used to harvest new seeds in the spring. If the seeds are used in the first year, they will grow seeds after they grow.
The coriander seeds must be stored for 1 year before they are used, but the storage time should not exceed 3 years. The new seeds have a strong odor of parsley, and the scent of the Chen seeds becomes lighter.
The leek seeds must use new seeds of the current year. If the seedling rate is greatly reduced every other year, even if the seedlings emerge, they will wither.
Cabbage seeds can be stored for 2 years. Seeds harvested that year can be planted in the same year. For more than 2 years, the emergence rate generally decreases by 20% to 27%, and the disease resistance becomes lower.
In actual production, the use of vegetable seeds every other year is safer. This is because some vegetable seeds are dormant and new seeds are prone to seedling emergence. Except for leek and onion seeds, most of the seeds have a useful life of 2 to 3 years or 4 to 5 years. For example, the third year old seeds of celery have a higher germination rate. In fact, the lifespan of seeds is very different depending on the storage conditions. The experiment showed that the radish seeds used in the radish could inhibit the growth of the underground and promote the development of the underground; the seeds of the mung bean had the effect of increasing yield.
