What is the purpose of seed bank?

A seed bank (also seedbank or seeds bank) stores seeds to preserve genetic diversity; hence it is a type of gene bank. There are many reasons to store seeds. The genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc. of crops. Can all seeds be banked?

What is the difference between a seed bank and gene bank?

A seed bank is a type of gene bank. A gene bank, sometimes called a gene library, is essentially a collection of genetic material. These banks can house up to hundreds of thousands of crop variety seeds, seedlings, even plant and animal tissue samples. Think of a seed bank as a safety warehouse for crop diversity.

Plus, it is easy, takes little space, and the seed can be stored season after season. Starting a seed bank as a home gardener involves little effort and may start with saving seed from home grown plants or sourcing regional and native seed.

How do seed banks store their seeds?

To reduce the moisture content of the seeds, collectors dry them in a temperature- and humidity-controlled room. Afterwards, they place the seeds in sealed, airtight containers. The final storage step is to freeze the seeds at minus 4 degrees Fahrenheit (minus 20 degrees Celsius).

Are seed banks worth it?

Seed banks protect and save plant genetic diversity, which is important for a number of reasons. These saved and viable seeds contain a treasure trove of useful genes that breeders can use for developing improved varieties of our major food crops.

What are the disadvantages of seed banks?

Why are seed banks important?

Conservation efforts such as seed banks are expected to play a greater role as climate change progresses. Seed banks offer communities a source of climate-resilient seeds to withstand changing local climates. As challenges arise from climate change, community based seed banks can improve access to a diverse selection of locally adapted crops while also enhancing indigenous understandings of plant management such as seed selection, treatment, storage, and distribution.

Collections must also be efficient and that means they mustn't duplicate materials already in collections. Keeping seeds alive for hundreds of years is ...

How to preserve seeds?

The document advocates drying seeds to about 20% relative humidity, sealing seeds in high quality moisture-proof containers, and storing seeds at −20 °C (−4 °F). These conditions are frequently referred to as 'conventional' storage protocols. Seeds from our most important species – corn, wheat, rice, soybean, pea, tomato, broccoli, melon, sunflower, etc. – can be stored in this way. However, there are many species that produce seeds that do not survive the drying or low temperature of conventional storage protocols. These species must be stored cryogenically. Seeds of citrus fruits, coffee, avocado, cocoa, coconut, papaya, oak, walnut and willow are a few examples of species that should be preserved cryogenically.

How to keep seeds alive?

Seeds are living plants and keeping them viable over the long term requires adjusting storage moisture and temperature appropriately. As they mature on the mother plant, many seeds attain an innate ability to survive drying. Survival of these so-called 'orthodox' seeds can be extended by dry, low temperature storage. The level of dryness and coldness depends mostly on the longevity that is required and the investment in infrastructure that is affordable. Practical guidelines from a US scientist in the 1950s and 1960s, James Harrington, are known as 'Thumb Rules'. The 'Hundreds Rule' guides that the sum of relative humidity and temperature (in Fahrenheit) should be less than 100 for the sample to survive five years. Another rule is that reduction of water content by 1% or temperature by 10 °F (5.6 °C) will double the seed life span. Research from the 1990s showed that there is a limit to the beneficial effect of drying or cooling, so it must not be overdone.

Why do we bank seeds?

Since we have been farming, we have been banking seeds. 12,000 years ago, when agriculture began in the Fertile Crescent, seed banking was necessary to protect seeds from weather and animals. One method of protecting seeds involved packing them alongside ashes inside of baskets and then burying the baskets ( Seabrook ).

The importance of preserving native and wild species of seeds has never been higher than in today’s world. Agricultural giants are expanding their proprietary varieties, which threaten to encompass original and heirloom species. Collecting and storing seed species provides a consistent source of plant populations that may be threatened by modified seed, loss of habitat and lack of diversity.

Why is seed saving important?

Additionally, seed saving can create opportunities for agriculturally challenged regions and poor farmers when excess seed is donated. Seed bank information can be found at the local, regional and even international level, as many countries are actively involved in preserving their native plants.

Where to store seeds in the National Seed Bank?

While the national seed bank has a concrete underground bunker for the complete collection, with climate control and extensive data bases, this is by no means the only way to store and collect seeds.

When did seed banking start?

Scientists believe agriculture began as far back as 8000 B.C., in the mountains of Mesopotamia, now present day Iraq. Even then, farmers realized their seeds needed protection in order to ensure the next year's harvest.

When were seed banks discovered?

In Iraq, scientists have discovered evidence of seed banks from as far back as 6750 B.C. [source: Seabrook ]. Back then, seed banks protected seeds from animals and extreme weather. Today, we store seeds for different reasons.

Why do we store seeds?

Back then, seed banks protected seeds from animals and extreme weather. Today, we store seeds for different reasons. The most essential reason is crop diversity. Just as humans have specific genetic traits, so do plants. And just as humans have evolved and adapted to specific conditions over time, so have plants.

Why do we need to preserve seeds?

Aside from crop diversity, there are many other reasons we need to store and preserve seeds: 1 Climate change: Scientists are concerned that climate change will cause extreme weather conditions and bring new pests into some environments. These events could cause certain species of plants to go extinct [source: Rosenthal ]. 2 Natural disasters: Natural disasters can wreak havoc on a region's ecosystem. After the 2004 tsunami destroyed rice paddies in Malaysia and Sri Lanka, international seed banks provided local farmers with varieties of rice to begin growing their crops again [source: Roug ]. 3 Disease: Disease quickly and easily wipes out crops. For example, a recent strain of disease called stem rust (Ug99) may have the capability to infect up to 25 percent of the world's wheat supply [source: Singh ]. 4 Man-made disaster: Man-made disasters can be as devastating to plant life as natural disasters. An obvious example would be war. In fact, one of Iraq's vital seed banks was looted during fighting [source: Pearce ]. 5 Research: Indigenous people have used plants to cure sickness for centuries. One in every six wild plants is used for medicinal purposes [source: Levine ]. Who knows what diseases the right plant or herb could eradicate?
