Orthodox seed

Orthodox seeds are seeds which will survive drying and/or freezing during ex-situ conservation. According to information from the U.S. Department of Agriculture there is variation in the ability of orthodox seeds to withstand drying and storage with some seeds being more sensitive than others. Thus some seeds are considered intermediate in their storage capability while others are fully orthodox.[2] One notable example of a long-lived orthodox seed which survived accidental storage followed by controlled germination is the case of the 2,000 year old Judean date palm (cultivar of Phoenix dactylifera) seed which successfully sprouted in 2005.[3] This particular seed was reputed to be the oldest viable seed until the sprouting of Silene stenophylla seeds more than 30,000 years old, but the upper survival time limit of properly stored seeds remains unknown.[4]
