What is germination ratio?
Germination ratio is the proportion or percentage of seeds that successfully sprout and begin to grow under ideal conditions. It is often used to assess the quality and viability of seeds for planting purposes.
When does germination in a plant begin?
Plant germination begins when the seed has all the required conditions ( like optimum temperature, pH, water etc. ) before losing it's viability.
What are the objective of seed viability?
The objectives of seed viability testing are to determine the germination potential of seeds, assess seed quality, predict seedling emergence rates, and ensure successful crop establishment and production. Testing seed viability helps growers to make informed decisions about seed storage, planting rates, and seed treatment strategies.
Does freezing affect seed germination?
Freezing can damage seed tissues and reduce viability, affecting the germination process. Ice crystals can form inside the cells and disrupt membranes, leading to cell death. It is generally recommended to store seeds in cool, dry conditions above freezing temperatures to maintain their viability.
What are the methods of testing the viability of a seed?
Common methods for testing seed viability include the tetrazolium test, germination test, and conductivity test. The tetrazolium test involves staining seeds to assess their internal structures, the germination test involves planting seeds and monitoring their sprouting, and the conductivity test measures the electrical conductivity of seed leachate to determine seed viability.
How seed are selected to germinated?
Seeds are selected for germination based on factors like seed size, weight, shape, color, and overall health. Additionally, seeds are tested for viability through methods such as the tetrazolium test, germination test, and cutting test. Only seeds that meet quality standards and have a high probability of germination are selected for planting.

How can you determine if cucumber seeds are good?
To determine if cucumber seeds are good, you can perform a germination test by placing a few seeds on a damp paper towel in a warm place. Good seeds will sprout within a few days, indicating their viability.
Does the age of a seed affect the rate of its germination if yes how?
yes. the seed is a living organism, although in an apparent state of suspended animation. while the seed lies dormant it still metabolises - that is it uses it reserves of stored energy (stored in the cotyledons) to stay alive. Some seeds metabolise at a very slow rate and such have a very long "storage life", others may metabolise at a faster rate or have smaller cotyledons - which then shortens their lifespan. Seed viability (rate of germination after storage) is pretty much constant for a particular kind of seed; this can vary from between a few months up to 20 years. The average though is in the region of 4 to 5 years, after this time the germination of the seed batch will have decreased to almost zero. there is an account however of a date palm seed being successfully germinated after almost 2000 years! after it was discovered at an archaeological site in the middle east. viability deteriorates on in a linear fashion per seed batch.
How many years are vegetable seeds good for?
It depends on the type of vegetable and the conditions in which they are kept. Percentage viability will always drop off over the years.
Can a seed be viable and dormant at the same time?
Yes, a seed can be viable (able to germinate) and dormant (not actively growing) at the same time. Viability refers to the seed's ability to germinate under favorable conditions, while dormancy is a period of arrested growth or development. Seeds can remain dormant for extended periods until conditions are suitable for germination.
