Seed dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival. [1] Dormant seeds do not germinate in a specified period of time under a combination of environmental factors that are normally conducive to the germination ...
Seed dispersal is likely to have several benefits for different plant species. Seed survival is often higher away from the parent plant. This higher survival may result from the actions of density-dependent seed and seedling predators and pathogens, which often target the high concentrations of seeds beneath adults. [4]
Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores ( seed predators) feed on the seeds of plants as a main or exclusive food source, [ 1] in many cases leaving the seeds damaged and not viable. Granivores are found across many families of vertebrates (especially mammals and birds) as well ...
Carbon-dated. The oldest viable seed that has grown into a full plant was an about 2,000 years old Judean date palm seed, recovered from excavations at Herod the Great 's palace on Masada in Israel. It had been preserved in a cool, dry place, not by freezing. It was germinated in 2005. [ 3][ 4][ 5][ 6]

The Svalbard Global Seed Vault ( Norwegian: Svalbard globale frøhvelv) is a secure backup facility for the world's crop diversity on the Norwegian island of Spitsbergen in the remote Arctic Svalbard archipelago. [ 5] The Seed Vault provides long-term storage of duplicates of seeds conserved in genebanks around the world.
Vincetoxicum rossicum reproduces by spreading its seeds through wind dispersal and through vegetative production. Since it is multiembryonic, it allows the seeds to cover more ground and allows the pale swallowwort to have a high reproductive rate. [1] Intermediate light is the best light source for the pale swallowwort to reproduce and grow. [1]
Clark's nutcrackers store seeds, usually in the ground for later consumption, in caches of 1–15 seeds (average of 3–4 seeds). [6] Depending on the cone crop as well as the tree species, a single Clark's nutcracker can cache as many as 98,000 seeds per season. [ 7 ]
