It is called a seed bank for the collection of a variety of seeds that accumulate in special environments to attest to their maintenance for a long period of time. You can find many seed banks all over the world, and they are of great importance for the conservation of species and for maintaining the health of the different ecosystems we inhabit. Some scientists consider that we are facing an era of mass extinction, as it is estimated that more than 30,000 species disappear annually.
The advantages of a seed bank for the conservation of species is, without a doubt, that they occupy very little space, compared to the area that would be necessary for their conservation in the form of live plants. Each of the seeds has a different genetic formation and therefore a single seed sample can save the diversity and extent of the genetic belonging of each species.
Most seeds are unprofitable, or have been banished from their ecosystem due to outpouring and contamination or because of their disappearance. Although we have to thank the diversity that the earth and the human being have, which have advanced to their current state, thanks to this, the planet is a niche of life.
Seed banks attest that we have enough biodiversity to face a future that we don’t know, but we deduce. The advantages that we have for the seed banks themselves are that we can maintain the variety of plant species for cultivation, as well as provide genetic diversity to achieve the development of other species and to replace the necessary seeds if the same are the losses during the sowing cause of a natural disaster. These seed banks are the insurance for the future of agriculture.
There are two classes of seed banks, transient and persistent; the transitory one refers to the seeds sown at about 5 centromeres from the surface and they sprout in a period of less than one year. Persistent banks are planted more than 5 centimeters before the transients are buried, they remain for many years without giving rise to new seedlings.
