What is seed banks? »Its definition and meaning

Anonim

It is called a seed bank to the collection of a variety of seeds that are accumulated in special environments to certify their maintenance for a long period of time. You can find many seed banks throughout the world, and they are of great importance for the conservation of species and to maintain the health of the different ecosystems that we inhabit. Some scientists consider that we are facing an era of mass extinction, since it is estimated that more than 30 thousand species disappear annually.

The advantages of a seed bank for the conservation of species is undoubtedly that they occupy very little space, compared to the area that would be needed for their conservation in the form of live plants. Each one of the seed has a different genetic formation and for this reason a single sample of seeds can save the diversity and the extension of the genetic belonging of each species.

Most of the seeds are not profitable, or they have been banished from their ecosystem by effusion and contamination or by their disappearance. Although we have to thank the diversity that the earth and the human being, who have advanced to their current state, thanks to that, the planet is a niche of life.

The seed banks certify that we have enough biodiversity to face a future that we do not know, however, we deduce it. The advantages we have to own seed banks is that we can maintain the variety of plant species for cultivation, as well as providing genetic diversity to achieve development of other species and to replenish the seeds necessary if the same are 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, the transitory and the persistent, the transitory refers to the seeds sown at about 5 centromeres from the surface and these sprout in a period of less than a year. The persistent banks are planted deeper than 5 centimeters that the transients are buried, they remain there for many years without originating new seedlings.
