Stratification of seeds may affect the disappearance of inhibitors and the buildup of germination promoters such as the gibberellins and cytokinins. Natural stratification occurs when seeds shed in the fall are covered with cold soil, debris and snow. In artificial stratification, layers of seeds are alternated with layers of moistened Sphagnum sand or some other appropriate material and stored at low temperatures.

Assertion : Stratification of seeds may promote their germination.Reas...
Assertion-Reason Question Explanation:
Assertion:
- The assertion states that stratification of seeds may promote their germination.
Reason:
- The reason provided is that stratification is promoted by gibberellin and cytokinins.
Explanation:
- Stratification is a process in which seeds are exposed to cold and moist conditions to break dormancy before germination can occur. This process is essential for seeds of certain plant species to germinate successfully.
- Gibberellins and cytokinins are plant hormones that play a crucial role in seed germination. Gibberellins promote the growth of the embryo and seedling, while cytokinins regulate cell division and growth.
- When seeds undergo stratification, the cold and moist conditions trigger changes in hormone levels, including an increase in gibberellins and cytokinins. These hormones help in breaking seed dormancy and promoting germination.
- Therefore, the reason provided is correct in stating that gibberellin and cytokinins are involved in promoting stratification and subsequently germination of seeds.
- However, it should be noted that while the reason supports the assertion, it does not directly explain why stratification promotes germination. The correct explanation lies in the fact that stratification breaks seed dormancy, allowing the embryo to resume growth and ultimately leading to germination.
Therefore, option 'B' is the correct choice for this Assertion-Reason question.
