Why is Cryopreservation Important to Endangered Native Plants?

Cryopreservation, a method of storing tissues in liquid nitrogen, is becoming increasingly important to rare plant conservation. This is because many plant species, including large groups such as oaks, orchids, and bryophytes, are unable to be stored long term using more traditional seed banking methods. 使用超低温保存技术,研究人员能够保存更多的农作物[…]
