Agronomically, seed is not simply a germinating grain. It has in its bosom its identity, which is genetic purity, assuring all the agronomic qualities of the future plant, to which it will give rise. The seed has the physiological and sanitary qualities, which are the translation of its health, of its vigor, characteristics that are so important in the uniform and timely establishment of the new crop. The seed has its physical quality, which assures its users the integrity of not containing physical impurities and seeds of weeds, which can detract from its performance in the field, as these components can be carriers of undesirable diseases and weeds, which may jeopardize the production of the new crop.
Paraphrasing Professor Chotaro Shimoya (Federal University of Viçosa): "Seed is a wonderful case in whose bosom the future plant is in."
Botanically, seed is the ovum developed after fertilization, which contains embryo, nutritional reserves and integument. It represents a mean of survival of the plant species, since it resists the adverse conditions of desiccation, that would be fatal to the plants of these species, being able, therefore, to develop and to originate a new plant. It represents an efficient way of surviving and reproducing the various plant species through time and space, used by nature and man to distribute genetic improvements to successive generations.
Seed Quality Concepts: Greater germination and vigor, better sanity, guarantee of greater physical and varietal purity, free of invasive seeds.
With all these attributes, it brings in its range a number of benefits that contribute to the success of the crop.
The seed has a very special particularity because it is the messenger of the change in the culture environment. The seed was the basis of social organization in the early days of mankind.
Going back a bit in time, some paleontologists consider that the first hominids appeared about a million years ago in the North and East regions of Equatorial Africa. Since then, and until about 10 to 12 thousand years ago, man can be considered to have evolved very little, with only minor advances in his cultural aspects, creating tools, developing techniques of hunting and survival.
However, about 10 to 12 thousand years ago, in the regions of Asia of the Monsoons (South and Southeast Asia) and the Middle East, the man, who had hitherto lived in nomadic ways and who subsisted on hunting and extractivism, discovered the seeds of the wild plants he collected for food, falling to the soil, and finding suitable water and temperature conditions, germinating and producing new plants, which could be nourished and reproduced again. It is likely that this discovery was accidental. Man's behavior could then be radically modified, setting himself in desired places, cultivating his food and forming the first communities. Therefore, the realization of the seed-plant-seed relationship played a fundamental role in the development of agriculture and in the history of civilization.
The seed represents a means of survival of the plant species, since it resists the adverse conditions of desiccation, that would be fatal to the plants of these species, being able, therefore, to develop and to originate a new plant. It represents an efficient way of surviving and reproducing the various plant species through time and space, used by nature and man to distribute genetic improvements to successive generations.
To work with seeds is to have with us a sense of time mastery, because, as Professor Julio Marcos Filho (ESALQ / USP) has said, "seeds represent the connection between the past and the future. They contain the accumulated genetic experience in the past and the potential for perpetuation in the future. "
In addition, the seed has great economic importance as food, since it corresponds to 60% to 70% of the food consumed worldwide, being transformed by the agroindustry in a variety of products.
The man who works with seed has the noble mission of contributing to the survival of the species, whether vegetable or human. To produce seeds is to work with life. The life present in the act of its multiplication, the future life in the security of the feeding of humanity.
