Each seed has its own ideal sprouting time. After three to five days the sprouts will have grown 5 to 8 centimetres (2 to 3 in) in length and will be suitable for consumption. If left longer they will begin to develop leaves, and are then known as baby greens. A popular baby green is a sunflower after 7–10 days.
Seed dormancy. 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 ...
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
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]
