Seed quality refers to the extent to which seed quality and sowing quality meet requirements or potential needs. It requires a qualified inspection agency to test the judgement. This process requires manpower, material resources, and time. When the breeders are in urgent need of planting, they can also determine their own size based on certain methods. Here's how to easily determine seed quality based on seed gloss, plumpness, clarity, and odor.
1 gloss
The color of the seed epidermis varies, and generally good seeds have a glossy appearance. It is best to put the seeds on a black chassis to see the color, avoiding strong light or weak light. For example, pepper seeds are light yellow and eggplant seeds are yellow-brown. The gray color of the seeds is mostly seeds of seed or poorly preserved seeds. Seedlings that are too light in color are poorly matured. Seeds that are dark in color are those in diseased or rotten fruit.
2 fullness
Seed fullness is one of the characteristics of a good seed, resulting in late or poorly developed fruit seed with poor growth and poor plumpness. The fullness of the seed can be measured in terms of thousand grains. For example, common eggplant seeds have a grain weight of 4 to 5 g, and a grain weight of less than 3 g is mostly a seed of poor plumpness.
3 Clarity
The higher the seed's clarity, the better the quality. The clarity of the seed is generally expressed as a percentage of the total weight of the test seed after removing the trash and the spent seed. The clarity of good seeds should not be less than 98%. If there are large-scale hybrids or other large-scale crop seeds in a random grab of a seed, it can be judged that the seed quality is not high.
4 smell
The seeds can be placed on the hands and scented after being smelled with the nose, or the seeds can be covered and soaked in warm water of 60-70° C. for 2 to 3 minutes. The fresh and excellent seeds should have the unique fragrance of the seeds. If the pepper seeds are hot and spicy, cabbage seeds such as cruciferous seeds have a clear scent, celery seeds have a strong scent, and onion and garlic seeds have a wine or musty taste. If the seed is different
Odor, mildew or mild taste indicate poor seed quality.
5 purity
Seed purity refers to the degree of uniformity of the botany and biology typical traits of a variety. The higher the uniformity of the seed size and color, the better the purity of the seed. The mixed colors of the seeds indicate poor seed purity. Generally, the seed shape and organ position are observed and judged. For some seed seeds, such as hawthorn seedlings, water celery, etc., the size and color of the leaves and stems can be determined.
Determine the degree of uniformity.
