1) Dish Method 2) Rag-Doll Method 3) Seed Box Method
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.
Wind is the best method of seed dispersal.
what is test-retest method
No, good seeds do not always sink in water. Some healthy seeds may float due to air pockets inside the seed coat. It is best to refer to specific instructions for each type of seed to determine the appropriate method for testing seed viability.
The rag doll method and the dish method
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.
