Seed viability is the embryo’s capacity to germinate and is regulated by a variety of environmental factors (or) Seed viability refers to the capacity of a plant structure (seed, cuttings, etc.) to exhibit life characteristics, such as germination and growth.
What is the definition of seed viability?
Germination refers to whether or not a seed can germinate. viability refers to whether or not a seed is alive. The discrepancy between the quantity of viable seeds in a collection and the number of seeds that can germinate is that some seeds are immature or latent (‘sleeping’).
After accordance with the usual germination period indicated on the seed packaging, examine the seeds in a few days to see how many have sprouted. If you are unaware of the usual germination rate, examine the seeds in 7 to 10 days. They could be visible through the paper towel.
Usually, the roots develop first. Once they have begun to germinate, remove the paper towel-wrapped seeds carefully from the bag. Unroll the paper to determine how many seeds have germinated. The germination test will reveal what proportion of the seeds are still alive. If just fifty percent of the seeds germinated in the paper towel, it is probable that only fifty percent will grow in your garden.
If the germination rate is between 70 and 90 percent, you should spread the seeds a bit more densely than usual. If less than 70 percent of the seeds germinate, it may be best to purchase new seed. The sprouting seeds can be planted in the ground or in a container.
Given that the root typically develops into the paper towel, cut or rip around the seeds and then plant them with the towel. The water technique can also be used to test larger seeds. Put peas, beans, and maize in water in a dish. If they sink, it is acceptable. If the object floats, toss it. Seeds have a longer shelf life when kept in a cold, dry environment.
In the winter, a basement or garage that is cool and does not freeze is useful. A cold room or refrigerator will maintain them at the ideal temperature and humidity level during the summer.

What are viability and vigor of seeds?
Distinction Between Seed Viability and Seed Vitality A viable seed is one that is capable of germination. However, not all viable seeds possess the vitality to germinate and mature into beautiful, robust plants. Seeds are nature’s method for preserving life for future generations, although some seeds are more resilient than others.
- Read this article to learn what seed viability and vigor represent and how to distinguish between the two.
- Viability A viable seed is one that is capable of germination under appropriate conditions.
- It is the capacity of plant structures (seeds, cuttings, etc.) to exhibit life characteristics such as germination and growth.
It is essential to comprehend that seeds stored in a gene bank will grow into plants. Therefore, they must be extremely viable initially and during storage. Given the climatic conditions, the storage life of an accession will be determined by the viability of the seeds at the start of storage.
Vigor According to a commonly accepted definition, vigor is “the sum of those properties of the seed that affect the potential level of activity and performance of the seed during germination and seedling emergence.” When cultivated under optimal conditions, seeds from a variety of sources can achieve comparable germination rates.
Due to variations in vigor, these same seeds may have drastically varied abilities to produce plants in the field’s harsher conditions. Difference Between Seed Efficacy and Efficacy
|Seed Viability||Seed Vigor|
|Seed viability refers to a seed’s capacity to germinate and produce a healthy seedling.||Seed vigor refers to how quickly seeds germinate.|
|The viability test is used to determine if a seed sample contains alive or dead seeds.||The seed vigor test distinguishes between high and low vigor seeds.|
|Seed viability tests include ‘The Germination Test’, Quick Viability Test or TZ test, etc.||Seed vigor tests include Accelerated Aging Test, Cold Test, etc.|
|The viability of a seed decreases when it reaches physiological maturity.||Various seeds have different levels of vigor.|
|Viability test can be conducted using a single variety of seeds.||A minimum of two different species of seeds are required for seed vigor testing.|
|Seed viability can be measured in percentages.||Seed vigor is merely a comparison of the resilience of one seed species over the other.|
Conclusion Seed vigor is a more complex trait than seed viability, since it is determined at several stages of the mother plant and seed’s development, as well as by the surrounding environment. In addition, its effects are environment-dependent and occur from seed germination to seedling emergence.
- Seed vigor and viability tests are essential to agriculture and the seed business, yet they remain poorly understood and understudied in academic study.
- With a growing human population and rapid climatic change, seed vigor and viability testing is gaining in significance.
- We hope this article has illuminated what is known about seed vigor, viability, and their impact on crop output.
Future food security requires more research into these confusing and intricate characteristics, as well as the development of innovative tools for comprehending them.
