Today’s preservation techniques has been developed on the base of natural occurring phenomenon’s like sporulation ,germination, hibernation, adaptation etc, that is found in different animals and in microorganisms. All above and many other sophisticated preservation techniques are today being used in giant projects that are going on. One of such project is Millennium Seed Bank Project. This project is an international conservation project which aim to preserve rare and endangered species of plant from around the globe. This project is coordinated by Royal Botanical Garden, Kew which is launched in year 2000.
As per the plan they will be collecting and preserving around 50,000 species of plants which fall under such categories. They also collect seeds from the entire native UK’s flora. Once such seeds are collected, they do research and develop new methods for their preservation as well as propagation in future. Each plant’s seed has its own protocol for germination and propagation in this bank. This way they will preserve all valuable flora form around the world.
The most important thing is that the rare species are being developed and propagated with these preserved seed using various techniques like tissue culture and other micro-propagation etc. This project is the largest and successful preservation of valuable seeds which can be used in future as and when required. These seeds are preserved in liquid nitrogen, or below temperature like -20 to -80 °C.
The collect seeds are billion in number and variety. By today, these stocks represents around 12-15 percent of total of globe. It means still there are many species which will be preserved and can be used in future depending upon their number in existence.
Such projects are not only a hope for plants under threat of extinction but also saves medicinal and other valuable plants on which we are dependent.
