What are the methods of testing the viability of a seed?
Dish method...rag-doll method..Seed-Box Method..
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.
What are the methods for testing seeds for germination?
Generally seed require a few things in order to germinate:Water/ moistureSoil (or a growing medium)Heat/ warmthDarkness or in the case of some seed lightGeneral guide is that the seed should be covered to double the diameter of the seed itself. In the case of many small or fine seed varieties it is best to leave them uncovered with soil.Keep the soil moist during germination, but not too wet as this can cause fungal problems.It is always best to research the seed variety you are germinating if you are not sure of the specifics - as different seeds have different germination periods.
Is sunlight needed in the germination of seed?
You need to put one seed in a pot of soil and place it in a room where there is no light and place another plant in a pot without soil and under a window as there are a lot of light. After a few days, you will see that the seed in the soil pot light will germinate, and you can conclude that a seed does not need light to germinate but need soil.
Increases bone strength and viability by pulling action?

What is viability?
The viability of a seed is the chance that an individual seed will germinate. Viability means its chance of success.
Which seed has retained viability for thousands of years?
rice

Is a combination of germination percentage germination rate seed viability and strength shown by seedlings?
VIGOR
What happens to a seed if it does not get the things it needs to grow?
Its viability is lost in due course of time and deteriorates.
Why doesnt all seeds grow into a new plant?
Due to dormancy and various levels of seed viability
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.
