Seeds are a very important part of plants or other organisms, which can be used to ensure the life energy and excellent characters of future generations. Seeds play an important role in modern agricultural production and scientific research because of their excellent durability and preservation.
1. Composition of seeds
Seeds are mainly composed of ovule, seed coat, endosperm, nutrients and other physiological and biochemical components; Their main function is to provide necessary conditions for germs, such as nutrition, moisture, oxygen and protection; The seed coat of a seed has the protection function of external interference and pathogen invasion, and there are also important nutrients and growth regulators on the seed coat.
2. Classification of seeds
Seeds can be classified according to cell structure, biological characteristics and morphological characteristics. At present, it is common to classify seeds according to their morphology, exercise mode and nutritional reserve. According to the morphology, it can be divided into gymnosperm seeds and angiosperm seeds;
The seeds of gymnosperms have simple ovule structure, and have not experienced gonad development and endosperm formation, and the seed coat is close to the ovule. Angiosperm seeds have stages of gonadal development and endosperm formation in the floral organs of angiosperms.
3. The importance of seeds
Seeds are extremely important in modern agricultural production, and they are the main means of reproduction for crops such as grain, oilseeds, vegetables and fruits. Seeds are also often used in scientific research, as important materials for genetics, physiology, molecular biology and other research;
In addition, seeds are also widely used in ecological restoration and other fields. Through the germination and growth of seeds, the land can be effectively restored and the ecological environment can be protected.
4. Preservation and transportation of seeds
In the process of seed preservation, attention should be paid to controlling the environmental temperature and humidity to keep it dry and cool; The storage time of seeds also varies with the variety, storage conditions and storage methods. Generally, under normal storage conditions, the germplasm characteristics of seeds can be preserved for more than ten years.
The transportation of seeds needs to take protective measures, such as packaging and processing, to reduce the probability of seeds being damaged by germs and insects.
To sum up, seeds are an important part of plants or other organisms, which can ensure the life energy and excellent characters of future generations.
Seeds play an important role in modern agricultural production and scientific research. It is of great significance for modern agricultural production and scientific research to deeply understand and master the composition, classification, importance, preservation and transportation of seeds.
