A Seed Can Be Alive and Still Not Sprout

Viability concerns whether a seed has the living capacity needed for germination and development under an appropriate assessment. Dormancy can prevent a viable seed from germinating even when otherwise suitable external conditions are present. Unsuitable external conditions can also prevent germination without being the same thing as dormancy.

Draw three boxes: living capacity, internal restriction and current external conditions. The boxes organize different questions rather than supplying a diagnosis. A result of no observed germination could be consistent with more than one explanation. The observation alone does not tell you which box contains the relevant limitation.

An appropriate species-specific method helps distinguish the questions by defining the conditions and any supported pretreatment. It does not promise that every individual seed will develop. Identity, seed history and the period considered remain important. A seed that looks intact also cannot be certified viable solely by its appearance.

For a fictional packet, write the actual observation before choosing an explanation: no germination was recorded by the named point under these described conditions. Then list what is missing. Were the species and its requirements known? Was the period sufficient according to the applicable method? Was dormancy considered? Keep nonviability as one possible explanation rather than the automatic verdict. This guide teaches the biological categories and the limits of the inference. It does not turn an ordinary home observation into an official viability assessment or provide a universal test for every seed type.
