Given below are two statements about vernalization. Statement I - Generally vernalization is effective at seed stage in annual plants. Statement II - The site of vernalization is believed to be shoot apical meristem. In the light of above statements, select the correct option given below:

Step-by-step solution

Vernalization is the process of inducing early flowering in plants by exposing them to low temperatures. Statement I is correct because in annual plants (such as winter varieties of wheat, barley, and rye), the cold treatment is typically effective at the germinating seed stage or seedling stage. Statement II is correct because the site of perception of the cold stimulus for vernalization is the highly dividing meristematic cells, primarily the shoot apical meristem or the embryo tip. Therefore, both Statement I an
