Tetrazolium test (TZ test) that was developed in Germany in the early 1940s by Professor Georg Lakon who had been trying to distinguish between live and dead seeds by exposing them to selenium salts. then he tried tetrazolium salts and found them more effective.

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.
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.
What is viability?
Viability refers to the ability of something to survive, grow, and develop under certain conditions. In a biological context, viability often relates to the ability of organisms to maintain life and functionality. It can also be used in other fields to assess the likelihood of success or effectiveness.
Do good seeds always sink in water?
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 protective covering around the seed of a angiosperm is called the?
The protective covering around the seed of an angiosperm is called the seed coat. It helps to protect the seed from damage and drying out, ensuring its viability during dormancy.
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.
Is a combination of germination percentage germination rate seed viability and strength shown by seedlings?
VIGOR
Why doesnt all seeds grow into a new plant?
Due to dormancy and various levels of seed viability
Will a cracked avocado seed still grow?
Yes, a cracked avocado seed can still grow as long as the crack does not affect the viability of the seed inside. It may take longer to sprout or have a lower chance of success compared to an intact seed.
Which seed has retained viability for thousands of years?
The oldest viable seed is approximately 32,000 years old and belongs to the Arctic flower Silene stenophylla. This seed was discovered in Siberia and successfully germinated in a lab.
How should I store seed potatoes in the refrigerator to ensure their freshness and viability for planting?
Store seed potatoes in a paper bag or cardboard box in the refrigerator to maintain freshness and viability for planting. Keep them away from light and moisture to prevent sprouting. Check regularly for any signs of rot or decay.
