Germination of seedlings raised from seeds of eucalyptus after three days of sowing. In agriculture and gardening, the germination rate describes how many seeds of a particular plant species, variety or seedlot are likely to germinate over a given period. It is a measure of germination time course and is usually expressed as a percentage, e.g ...
Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth. In the field of nutrition, the term signifies the practice of germinating seeds (for example, mung beans or sunflower seeds ) to be eaten raw or cooked ...
The germination percentage is simply the proportion of seeds that germinate from all seeds subject to the right conditions for growth. The germination rate is the length of time it takes for the seeds to germinate. Germination percentages and rates are affected by seed viability, dormancy and environmental effects that impact on the seed and ...

The second oldest viable seed recorded is a 1,300-year-old sacred lotus (Nelumbo nucifera) recovered from a dry lake bed in northeastern China in 1995. [ 7 ] [ 8 ] A previously unknown species of Commiphora , possibly the source of the biblical medicinal extract tsori , was successfully germinated from a single seed in 2010 and carbon-dated to ...
Seed enhancement is a range of treatments of seeds that improves their performance after harvesting and conditioned, but before they are sown. They include priming, steeping, hardening, pregermination, pelleting, encrusting, film-coating, tagging and others, but excludes treatments for control of seed born pathogens.
This cold moist period triggers the seed's embryo; its growth and subsequent expansion eventually break through the softened seed coat in its search for sun and nutrients. [ citation needed ] Cold stratification simulates the natural process by subjecting seed to a cool (ideally +1 to +3 °C [34 to 37 degrees Fahrenheit]) moist environment for ...
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.
