Seed definition
Commonly, the seed of a plant is called a seed. A bulb planted to produce a tulip is also a seed. A seed is a part of a seed product such as cereal, legume, tuber such as potato, root such as mint, ivy, rhizome or underground creeping stem such as lily, stolon or creeping stem above ground such as strawberry, leaf such as succulents, begonia, African violet, onion. Like hyacinths, tulips, pajush, like aloes and haworthias, are planted in the soil to sprout and form the base of the plant. The seed is a living relationship between the parents and the results, and it is the main factor in the propagation of the plant from one environment to another, which causes the continuity of generations. Biologically, the seed is a ripe and fertile egg that has the ability to grow and become a complete plant, but in terms of agriculture and seed cultivation, it has a wider meaning.
Access to seeds, improved varieties of agricultural and ornamental plants with high quality is one of the requirements for the development of the agricultural industry and as a result, export and proper growth. The seed industry plays a vital role in this industry by expanding production capacity, increasing efficiency, speed of production of new cultivars and maintaining the genetic purity of these cultivars. The mechanization of planting and harvesting with harvesting machines and the problem of combating pests and diseases and lack of water has prompted seed production companies to adapt their seeds to the demands of the new technology of seeds with characteristics of short legs, long legs, and low yield. Quality, full of low-quality products, resistant to diseases and pests, they produce different colors and tastes, and because of this, good seeds are a little expensive, but of course, the increase in yield and the high quality of the product compensates for the cost.
The characteristics of a good seed
▪️ The first signs of its value are determined by the mass of a thousand seeds, smell and color in the seed set. It should also be fully ripe and contain the necessary nutrients for the fetus. Other signs of good seed can be determined from subsequent tests. Among the factors of its quality is the power of seed germination, which is the percentage of seeds that germinate and turn green. Seed strength and seed germination rate can be determined by counting the percentage of sprouted seeds in a certain period of time, for example, 10 to 15 days. Determining the germination power is very simple, and with tools such as wet cloth, drying paper, etc., a certain number of seeds, for example 10 or 100, are greened at room temperature and their percentage is determined.
▪️ It should be of suitable cultivars or hybrids, and the growth period of the plant should be in accordance with the agricultural climate and cultivation systems of the place. ▪️ It must be pure (pure in terms of type or variety), have high agricultural quality (seeds that germinate early and produce strong seedlings in normal conditions), have good yield potential, have a uniform growth and ripening pattern, and the purpose of cultivation and fulfill the task. ▪️ be free from any diseases and physiological disorders caused by lack of food. ▪️ Each grain should be large, same size as others and uniform in terms of shape, color, composition and weight. ▪️ It should be clean and free of materials such as pebbles, soil granules, straw and sticky materials such as gum and fruit juice. It should be free of harmful seeds such as weed seeds. It should be free of insects, insect eggs, spores, etc. It must be whole, unbroken, uncrushed and with a healthy shell. ▪️ It should be as fresh as possible or of a suitable age (not old). ▪️ It should contain the right amount of moisture.
