Gilbert White used hot beds warmed by manure to germinate melon seeds in England. [1] A seed germinator is a device for germinating seeds. Typically, these create an environment in which light, humidity and temperature are controlled to provide optimum conditions for the germination of seeds. One type of germinator is the Copenhagen or Jacobsen ...
Some seeds germinate when the soil is cool 28–40 F (-2 - 4 C), and some when the soil is warm 76-90 F (24–32 C). Some seeds require exposure to cold temperatures (vernalization) to break dormancy. Some seeds in a dormant state will not germinate even if conditions are favorable.
There have been several seeds known at different times as the oldest viable seed. Dormancy allows seeds to survive for extended periods, which can aid in seed dispersal and spread out the growth and establishment of seedlings , increasing the likelihood that some of the next generations survive if conditions are not suitable for seedling ...
Lilies seed germination is classified as either epigeal or hypogeal. These classifications may be further refined as immediate or delayed. Whether a lily is epigeal or hypogeal may be related to survival strategies developed according to the climate where the lily originated. Epigeal lilies evolved in moderate climates.

While too high nitrogen levels could lead to a quality and quantity decline of the oil content in the seeds, moderate nitrogen levels lead to increased seed quality and quantity. [21] Because the evening primrose is a light-dependent germinator, it is important that the seeds are not planted too deep into the soil, about 0.5–1.0 centimetre (0 ...
"EMLA" designates East Malling / Long Ashton research stations who took the "M" stocks and developed virus free versions. For example., EMLA 7 is M 7 with a guaranteed virus-free stock. [3] EMLA characteristics are often different from the parent "M" rootstock. Note that nearly all the apple rootstocks in the industry are now virus free. [1]
